Tourist Minesweeper is a twist on the classic puzzle game, using a gridded map of real locations to highlight the spread of Airbnb in popular Spanish tourist destinations. If you’ve ever played Minesweeper (and who hasn’t?), you’ll recognize the rules - but here, instead of dodging bombs, you’re “sweeping” for zones of tourist pressure.Currently you can play Tourist Minesweeper on gridded maps
New code will probably have some errors, the compiler finds some of them and
refuses to produce the final program. So far so good. But code also contains
lots of issues that are not outright errors, they just look “suspicious” to the
compiler in one way or another. Some of them turn out to be actual errors, but
sometimes the code is totally okay in the specific context. The compiler can’t
tell for sure, so it emits a warning and keeps going. Different compilers and
different versions of those compilers print different warnings.
And then there are things that are not problems by themselves, they just make
the code harder to read, possibly leading to more problems down the line. Or
sometimes a tool can detect that you are using an “old-fashioned” way of doing
things and there is a better, more modern or more efficient way, to achieve the
same thing. Some of these issues are also detected by the compiler, but for
most programming languages there are extra tools, so called...

Vector Tile styles require icons are served in a sprite sheet. This contains all of the icons in one file. Years ago there were a few options for these, none of them great. These days, there are three common options: spreet, @basemaps/sprites, and sprite-one. The first is written in Rust while the other two are written in Javascript.
All have the same basic functionality of turning a folder of SVGs into a json+png spritesheet, and doing so at multiple resolutions. Spreet has the additional option of de-duplicating icons. If two icons are identical it will only put one copy in the PNG and reference the same image twice.
I benchmarked all three options with two sets of sprites: all the SVGs from OpenStreetMap Carto, and the OpenStreetMap Americana icons. The former is 973 icons and the latter is 248 icons. These are larger than a typical set of icons but are a good test.

One of my favorite recent side-projects has been Meet Cute, a playful web map that generates tiny “micro-romance” stories whenever you click on a location. The conceit is simple: click on a map, and out comes a love story set in the nearest town.
But behind that simple experience was a not-so-romantic technical problem: finding the name of the nearest town.

I’m importing boundaries in Croatia, and I’m almost done. So I wanted to describe my process so that someone else maybe doesn’t have to rediscover this process. Maybe there is a better one, but I didn’t find it.
Croatia in OpenStreetMap had admin_level=7 borders imported, but the borders were not precise. So my job was to import admin_level=8 into these. I had the data in .osm format, and a license that is compatible. I wanted to keep the history of the old boundaries, so deleting everything and just copying inside wasn’t a choice.
First we need JOSM, and some experience with it. We turn on the Expert Mode in View. We need to install the plugin “utilsplugin2”. Then we go to Map Paint Styles in Preferences, and turn on the “Admin Boundaries” style.
So the process goes like this. In JOSM I open the .osm file with all the admin_level=8 boundaries. Then I download the area where I intend to work, but I use “Download from Overpass API” feature. In it I add the next Overpass...

When using OSM’s iD editor in New South Wales, Australia, there are multiple background layers you can enable that show aerial/satellite imagery. Different imagery sources can vary greatly in terms of how recent and/or blurry they are. Here I’ll discuss my experience using them.
DCS NSW Imagery
This is my preferred imagery source, primarily because it’s very clear even at high zoom levels. You can see lots of detail which makes it great for mapping.
Unfortunately it’s also the oldest of the imagery sources for NSW. In Armidale it’s dated 2018, but other towns can be as old as 2009! You can enable the “DCS NSW Imagery Dates” overlay to see what date the imagery for a given area was taken.
Esri World Imagery
This is my second preference for mapping. When DCS proves to be too old and doesn’t show recent changes to the map, Esri does. It’s the most recent of the imagery sources, dated around 2023. You can see the date for a particular area by enabling the “Background Panel” -...

Hello,
I would like to ask if in your country there are officially designated areas designated by local authorities (such as municipalities, civil protection agencies, emergency services, etc.) for:
Short-term population management (assembly points, waiting areas, temporary gathering places after an event).
Long-term population management (tent camps, temporary housing sites, large shelters).
Management of external rescue operations in response to the call (logistics bases, areas dedicated to external rescuers arriving from elsewhere, equipment sorting areas).
These areas would be part of civil protection / emergency management planning, mapped and designated in advance, not improvised during the event.
Do such areas exist in your country? And if so, are they publicly available (e.g., through official maps, open data, local plans)?
Thanks in advance for your feedback!

OpenStreetMap (OSM) adalah basis data spasial yang Open Source. Data data pada OSM merupakan hasil dari kolaborasi dan kontribusi terbuka oleh kontributor dari komunitas sukarelawan. Namun mendengar kata kontribusi data untuk OSM, mungkin membuat sebagian besar masyarakat membayangkan proses yang sangat rumit, mulai dari harus menggunakan laptop, citra satelit, dan lain lain. Tapi ada loh cara yang yang sederhana untuk memberikan kontribusi, bahkan terasa seperti bermain game di smartphone. Caranya adalah dengan menggunakan aplikasi StreetComplete.
StreetComplete merupakan aplikasi yang memudahkan siapa saja untuk berkontribusi ke OSM tanpa harus jadi “ahli pemetaan” dulu. Alih-alih harus menggambar peta dari nol, aplikasi ini menyajikan misi-misi kecil berupa pertanyaan tentang lingkungan sekitar. Misalnya:
Apakah jalan ini memiliki trotoar?
Apa jam buka warung ini?
Apakah bangunan ini punya atap datar atau miring?
Tugas-tugas kecil tersebut muncul dalam bentuk ikon di...

I had the privilege of presenting about weeklyOSM at COSCUP 2025, Taiwan’s largest open source conference, held on August 9–10, 2025, at the National Taiwan University of Science and Technology (NTUST) in Taipei. This year also marked COSCUP’s 20th anniversary, making it an especially meaningful event to join in celebrating open source.
About My Presentation
My talk, titled “Behind the Scenes of weeklyOSM: How We Share OSM News Every Week,” focused on the inner workings of our community-driven newsletter.
For those unfamiliar, weeklyOSM is an independent, multilingual publication that has summarized developments in the OpenStreetMap (OSM) world every week for more than a decade—now surpassing 780 editions.
Key Topics
During the session, I highlighted:
weeklyOSM’s Mission – Connecting mappers worldwide by bringing local stories to a global audience. We aim to be the heartbeat of the OSM community, delivering the pulse of mapping activities around the globe.

Background
I’ve mapped in OSM for many years now, but more of my work and been Bike-Pedestrian related, and I’ve only just come back around to mapping streets their widths and their number of lanes as a means to start evaluating crossings in our area. This means, despite my many years of mapping, I’m pretty terrible at getting the number of lanes forward/backward/both_ways and the corresponding turns associated with them correct. It’s just not that intuitive, although I can’t think of a better option.
My solution
A while back I discovered the JOSM ‘map paint styles’ specifically the lanes and enhances lane styles and combined with some tagging presets I’ve gotten acceptable at mapping major roads and the ability to visualize if I’m doing things right is a huge benefit.
The 12m (39’) of road that once visualized, haunts me.
When mapping with visualizations, I ran across a short middle lane that is marked as not for use in either direction. Without visualizations, this section...

5 anni fa ho iniziato a mappare su osm e devo dire che non ho mai avuto problemi con la mia community italiana, sopratutto perché le opinioni si esprimono in maniera dettagliata e cordiale, nonostante possano essere diverse.
Da quando ho scoperto che ci fossero linee guida consigliate nella wiki per gestire le bbox, ho cercato di ricordarlo a tutti gli utenti (alle prime armi o esperienziati) per semplificare le operazioni di noi locals nella verifica delle modifiche.
Purtroppo ho incontrato utenti non italiani che hanno espresso, attraverso ogni mezzo, il loro disappunto con prese in giro, umiliazioni e tutto ciò che ha a che fare con il bullismo.
Questa differenza tra la community italiana (dove si ragiona con serietà) e la parte rumorosa della communitiy internazionale (dove si risponde a suon di provocazioni) mi ha colpito a fondo rendendomi triste e ferito.

Five years ago, I started mapping on OpenStreetMap, and I have to say that I have never had problems with my Italian community, especially because opinions are expressed in a detailed and cordial manner, even when they differ.
Since I discovered that there were recommended guidelines in the wiki for managing bounding boxes, I have tried to remind all users—whether beginners or experienced—about them, to make it easier for us locals to verify edits.
Unfortunately, I have encountered non-Italian users who have expressed their disapproval through teasing, humiliation, and everything associated with bullying.
This contrast between the Italian community (where people reason seriously) and the noisy part of the international community (where responses come in the form of provocations) has struck me deeply, leaving me sad and hurt.
At this point, I asked myself whether it really makes sense to continue improving the mapping of the territory where I live if I am surrounded by users...

As a passenger in a moving car, I like to do OSM field mapping, constantly scanning the view outside and noting every detail I can spot. The catch is, I need to do it fast. Too fast to worry about proper tagging or structured data entry. What I really want is an app that shows my current location on a basemap, lets me tap anywhere on it to drop a point, and attach a rough plaintext note. Later, once I’m back home, I could export all those coordinates and notes as a GeoJSON file, import it into iD Editor or JOSM, and take the time to think about proper tags.
A few weeks ago, while traveling to Bandung, I tried doing “quick, live mapping on the road” with Vespucci. It turned out to be a bit of a nightmare. Each time I spotted something, I had to stop the GPS autofollow, download OSM data, add a node, pick a tagging preset, fill out the details, upload, and then repeat the whole cycle. By the time I was done with one object, I’d already missed several others. That constant...

Saya memulai sebagai mapper sejak tahun 2012 dan mengenal OSM di medio 2015. Memperoleh data spasial dalam tugas kuliah di tahun 2015 masih sulit dan terbatas. Saat itu untuk mendapatkan data vektor spasial, harus digitasi peta raster Rupa Bumi Indonesia atau digitasi dari google earth. Setelah mengulik di peramban web, saya menemukan bahwa tersedia data spasial indonesia secara free melalui geofabrik. Ini adalah anugrah Tuhan yang luar biasa. Setelah saya telusuri, ternyata sumber data ini dari komunitas openstreetmap. saya mempelajari bagaimana data itu tersedia secara free, dan ternyata berasal dari sumber terbuka. Dan saya tertarik bagaimana menjadi kontributor. Tahun 2018 saya mengikuti lomba pemetaan bencana yang diadakan oleh BNPB menggunakan JOSM/ device input data openstreetmap, yang datanya dapat dimanfaatkan untuk penanggulangan bencana. Ini hal yang luar biasa untuk pemanfaatan data spasial dari sumber terbuka.

Good afternoon from sunny, hot, and muggy northeast Florida!
I am still learning OSM, who is not, and having a blast doing it. It is increadibly fun and incredibly fascinating. Always see and find something new every single day! Love it!
Right now I decided to make the jump to JOSM. I know it is a little or a lot complicated. Best way to learn is jump and start going. When I downloaded it the current version, 19423, was not active I down loaded a earlier version and needed to update. I was literally looking at help files, Googling it, asking questions, a lot. But, and don’t ask me how, I eventually landed the current version, 19423, on my computer. It was one of those moments that you have no clue how you did something but who cares its finally done.
To get started I did the LearnOSM again. I sometimes have to do it over and over to get the idea. Its a good refresher as well. For someone like me who has multiple challenges the fact OSM allows for going back and being able to...

I noticed that on OpenStreetMap we were missing types of surfaces for many important roads in Kosovo.
Car navigators use surfaces when routing and calculating travel times.
So entering this information became a goal, a time bound mission I could do on my own within a short period of time and see the results, which is just what I like.
The roads in OpenStreetMap are largely classified as primary (highways), secondary (regional roads), tertiary (local roads) and residential.
I decided to work on the first three and smaller sections connecting these classified as primary_link, secondary_link and tertiary_link. The first three for the most part are asphalt in Kosovo, and it’s easy to guess when this may not be the case. Being larger, it’s also easier to confirm on aerial photography that they are indeed paved in asphalt.
First, getting a view of the situation. Here, Overpass turbo is great.

Another year has passed since my last entry, and it’s about two years ago that I resided in Bonaire for half a year. I want to visit again, but there’s that man on the side of my shoulder whispering things about a sustainable world :) (Meaning I can’t simply visit for a couple of weeks, but should stay for a longer period of time.)
Last year (2024), the Dutch government made high resolution aerial photos of Bonaire. I’ve already updated and mapped several areas based on this. As this information is both high resolution and recent it is very useful for mapping. You can find more information about this on https://www.beeldmateriaal.nl/dataroom-caribisch-nederland

Resilience planning relies on accurate, current field data that reflects real-world conditions. Structured, location-aware workflows make that data reliable, easy to use, and ready for action. When the right information flows quickly from field to office, infrastructure resilience stops being theory and becomes something teams can build and maintain.

Hi there, and thanks a lot for your contribution! 🌟
Just a little tip for future edits: keeping changesets small and local can make things smoother for everyone.
It helps prevent conflicts, makes it easier for fellow mappers to review, and keeps the map even more accurate.
A few friendly suggestions:
• Focus edits within a small geographical area (like a single city, district, or province)
• Try not to mix far-apart locations in one changeset
• Save/upload before starting work in a totally different area
If you’re curious, the wiki explains more here:
osm.wiki/Changeset#Geographical_size_of_changesets
Thanks again for your mapping energy, and happy mapping! 🗺️
Why is it important to remind both new and experienced users to keep changesets limited to a specific area?
First of all, not all editors can handle loading large amounts of data, as happens with iD (link).
More importantly, a large bounding box (covering, for example, half the world or all of Northern Italy)...
Paper checklists may be familiar, but they fall apart fast, especially when you need clean data, real-time visibility, or a process crews will actually follow. Mobile workflows with Fulcrum bring structure, accountability, and speed to inspections, powered by an intuitive mobile app that streamlines business processes and supports workflow automation from the field to the office.

A Journey of Growth: NLT’s Evolving Role at TUgis
New Light Technologies (NLT) is proud to have served as the Platinum Sponsor of the 2025 Maryland GIS Conference (TUgis 2025). Our journey with TUgis has been one of significant growth and deepening commitment. Over the years, we have evolved from presenters and lower-tier sponsors to becoming a leading sponsor in 2025. This progression underscores our dedication to the geospatial community and our continuous efforts to advance geospatial solutions.
If you have recently visited the
download site for Photon dump files
you may have noticed the new site layout. The site has received a complete overhaul
with new types of dumps, new options for extracts and a nicer presentation.
Read here what has changed.
Region extracts replace country extracts
The old site used to host one large planet dump and then country extracts in the
extracts/by-country-code/ directory. The new layout rearranges how you can
find extracts: they are now organised by continent with each continent giving
you a list of available country extracts. For you as a user that means that
all file locations and names have changed.
Some of the country extracts were really tiny and didn’t make much sense to
have on their own. They have been merged to subregions like the
Caribbean islands.
If you need a single country from that subregion, download the JSON dump and
create a Photon database with a country filter. The section on JSON dumps
below explains how this...

Introduction
Humanitarian Openstreetmap Team (HOT) is an international team dedicated to humanitarian action and community development through open mapping.
Accurate and up-to-date data is essential for effective humanitarian response. Validators use tools such as JOSM and the HOT Tasking Manager to identify and flag errors and mistakes. From experience, i know that this is a complex and time-consuming endeavor.
One tool to save time and enhance the validation process is OSMCha.
The funding for OSMCha is currently at risk, which could lead to the degradation of this invaluable tool. In this diary, i want to highlight the essential role OSMCha plays in my own (and other’s) validation and quality maintenance workflow.
What is OSMCha
OpenStreetMap Changeset Analyzer (OSMCha) is a tool designed to monitor and analyze changes made to OpenStreetMap data. It enables data validators to quickly identify potential issues, track changes, and ensure data quality.

Every couple of years, sales organizations brace for the big territory
reorganization: costly consultants, months of meetings, anxious reps, and a
shiny “new map” that’s already ageing when it launches.
At Mapidea, we’ve seen this across industries—and we know there’s a better
way. Continuous Sales Territory Optimization uses a geospatial intelligence
system to track territory performance in real time, assess the impact of
changes, and make small, frequent adjustments collaboratively with the
people who know the field best.
It’s faster, less expensive, and far more effective. Why wait years for the

In collaboration with a local team in Grünstadt, Mannheimer Mapathons e.V. completed the mapping of the historic Jewish cemetery in early 2024 after five months of data collection. The cemetery was used by the important Jewish community from around 1700 to around 1937 and comprises 464 gravestones that are still visible. A high-precision Sparkfun RTK Facet GPS receiver was used for the survey. A map has been available online since May 2024. In recent weeks, with the support of the Heidelberg University of Jewish Studies, the names and dates of many of the oldest purely Hebrew gravestones have been catalogued and integrated into the map data. The translation work will continue with the aim of supporting both descendants and historical research.

While parks and public spaces are vital to public health, environmental resilience, and city infrastructure, many park systems still rely on outdated tools and informal routines that limit visibility, delay maintenance, and waste resources. With structured field data, consistent inspections, and spatial context, cities can manage park infrastructure assets more effectively, improve reporting, and extend the life of public spaces. By combining parks management software with mobile tools available on any mobile device, field crews can capture real-time data feeds, streamline maintenance tasks, and tackle backlogged tasks before they escalate.

Running together at CNG Conference 2025
On the last day of CNG Conference, we held a facilitated discussion to identify what our community needs to thrive.
As Chris Holmes noted in his opening keynote, the geospatial field has reached a pivotal moment. We have more data, better tools, and greater computational power than ever before. The question now is how we use these resources to address real-world challenges. The six themes below emerged from our discussions and will shape our collective work in the coming year.
These challenges are deeply interconnected. Progress in one area often enables progress in others. And with AI rapidly changing the landscape, we need to stay adaptable and collaborative. We invite governments, funders, educators, enterprises, and entrepreneurs to join our community in this ongoing effort.

In the past we have written about how one can study urban shrinkage with a specific emphasis on Detroit from both an agent-based modeling perspective and also from analyzing newspapers through natural language processing Keeping with the theme of Detroit and urban shrinkage we (Xiaoliang Meng, Yichun Xie, Junyi Wu, Heather Khan Welsh, Shi Zeng and myself) have a new paper entitled "Examining spatial expansion and stemming strategies of urban shrinkage: evidence from Detroit, USA" which was recently published in npj Urban Sustainability. In this paper we introduce a method for studying urban shrinkage by constructing multi-scale spatial structures based on urban network connectivity which we call gravity-networked spatial interaction zones-based spatial panel modeling or GSIZs-Spanel for short. We demonstrate this method by exploring the spatial processes and scopes of past urban shrinkage in Detroit between 2000 and 2020. If this sounds of interest, below you can read the abstract...

Recently the European Space Agency’s (ESA) Living Planet Symposium (LPS) was held in Vienna, Austria.
This was likely the world’s largest gathering of the Earth Observation community. The LPS website claims there there were 6500+ registered participants and 4200+ presentations & posters in 250+ sessions, but those are conservative numbers… I counted 4428 presentations & posters in 453 sessions.
Also it says there were 2300 “Children at the School Activities”, and I can confirm there were lots of kids at the conference (and on the metro). Awesome to see!
I attended LPS on behalf of Radiant Earth and the Cloud-Native Geospatial (CNG) Forum.
I was there to learn how CNG specs and tools are being adopted by the Earth observation community and to help build awareness. Given the size of the conference (it had 30 separate content tracks!), my first challenge was to determine what content would be presented where and...

In the current issue of Environment and Planning B, we (Boyu Wang, Na Jiang and myself) have a new editorial entitled "Generative AI and Urban Modeling". The premise of this editorial is that Generative AI (GenAI) is impacting all aspects of our daily lives and as such has we were wondering how will it impact urban modeling? For example, in the editorial we discuss how GenAI could speed up the overall urban modeling process. To demonstrate this we show how ChatGPT (and its built-in coding interface Canvas) can take published papers and build agent-based models from them (one being of an abstract space and another being spatially explicit). However, while model building is time consuming task, another challenge modelers face is how to incorporate decision making within them. To this end we also discuss how large language models (LLMs) have the potential to help with agent-decision making in the form of generating agent-personas or scheduling agent activities. We conclude the...

Terradepth, led by CTO Andrew Lunstead, focuses on helping people make
better decisions about the ocean, an environment less understood than the
surface of Mars due to data collection challenges. Their approach involves
both developing high-endurance autonomous underwater vehicles (AUVs) for
massive data gathering and the sensor-agnostic Absolute Ocean data platform
. This platform, built on CesiumJS, provides an intuitive, world-view
interface for managing and visualizing current and historical undersea
surveys. Terradepth supports critical sectors like offshore energy,
resource management, and defense. While accommodating data from any source,
Terradepth has consolidated its cloud operations within AWS, including
GovCloud for enhanced security. A significant innovation is leveraging
edge computing with Absolute Ocean to drastically reduce the "scan to
decision" time from months to mere hours, greatly enhancing the speed of
critical operations

The first paper was with Qingqing Chen and Linda See and was entitled "Using New Sources of Data for Urban Climate Modeling Generated through MLLMs on Street View Imagery. "As the title might suggest, this paper was about how one can leverage multi-modal large language models (MLLMs) to extract information on building height, age and function from street level photographs. We demonstrate this using street view images from Mapillary and than ask ChatGPT to estimate the building height, age and function and compare the results to authoritative data sources.

The way we observe our planet from orbit is undergoing a seismic shift,
moving beyond the limitations of traditional satellite tasking to embrace a
future of intelligent, interconnected Earth observation. This revolution is
powered by the synergy of "virtual constellations" – diverse networks of
coordinated sensors – and sophisticated "tipping and cueing" workflows,
where broad-area monitoring by some assets automatically directs
high-resolution satellites to points of critical interest. Underpinning
this entire evolution is the transformative power of Artificial
Intelligence, which not only automates the detection of subtle changes and
orchestrates complex tasking but also distills vast streams of imagery into
actionable insights, promising a more transparent, responsive, and
understandable world.
Interoperability isn’t about perfection—it’s about progress. Learn how incremental, machine-readable standards unlock real ROI and reduce integration costs.

Artificial intelligence is rapidly redrawing the boundaries of the
geospatial industry, unlocking powerful new insights and efficiencies at an
unprecedented scale. Yet, beneath the veneer of technological marvel and
the often-touted narrative of 'AI augmentation,' a more profound and
unsettling transformation is underway for its workforce. This investigation
delves into the stark realities of how AI and machine learning are not just
reshaping, but in many cases, actively replacing traditional geospatial
roles, forcing a critical reevaluation of skills, careers, and the very
future of human expertise in mapping and understanding our world. As the AI
wave crests, the line between assistant and successor is becoming
increasingly, and for some, alarmingly, clear.

One of our goals at CNG is to create a larger and more diverse community of geospatial data practitioners. While tremendous progress is being made to make geospatial data easier to access and use in the cloud, we know that there are many people in need of training and educational opportunities to benefit from this progress.
To this end, we are starting to experiment with issuing badges to recognize individuals who have completed cloud-native geospatial trainings. We have started by partnering with thriveGEO, a training and technical consulting company based in Germany. In April 2025, thriveGEO gave its first Cloud-Native Geospatial 101 training course and we have issued CNG Badges to course participants.
CNG Badges use the Open Badges Specification which allows us to give people a verifiable digital credential that asserts they have completed a CNG-approved training course. By maintaining a vendor-neutral view of the geospatial technology landscape, we seek to...
In the past we have explored how social media can be used to delineate earthquakes, study human-wildlife interactions, understand urban morphology, urban smells or locating wildfires among many other things. Keeping with the last topic (i.e., locating things), in a new paper published in GeoJournal entitled "Crowdsourcing dust storms in the United States utilizing social media data," Stuart Evans, Festus Adegbola and myself explore how we can use X (formerly Twitter) and Flickr to source observations of windblown dust. As such the paper demonstrates how social media data can act as supplementary source for dust events monitoring and captures the seasonal trends of such events. Furthermore, the paper highlights the potential of using crowdsourced data for the often overlooked field of dust monitoring that has substantial health and economic impacts. If this sounds of interest, below we provide the abstract to the paper along with some figures which showcase our methodology and...

A stark vision for America's fiscal future now casts an ominous shadow, as
the proposed Fiscal Year 2026 budget threatens a veritable demolition of
non-defense federal capabilities, launching an unprecedented assault on the
agencies underpinning our nation's world-leading geospatial infrastructure

spending . This plan strikes at the heart of essential government
functions, and even as it calls for "unprecedented increases for defense" ,
the National Geospatial-Intelligence Agency (NGA) faces a deep paradox: its
direct appropriations may rise, but devastating cuts to civilian partners
like NOAA, NASA, and USGS threaten to hamstring its operational
effectiveness, potentially forcing NGA to divert its own increased budget

critically weakened foundational support system. The reverberations are

The high cost of commercial remote sensing data is a major obstacle to
widespread adoption. As Keith Barber notes, 'Right now, the price point is
such that it's still cheaper to go hire 150 guys to walk that field than it
is to use the technology.' By refactoring the executability of the
commercial and government markets from a macro-economic perspective and
moving to a Defense-wide budget, the price per image or access would
decline, amortizing the value and creating a price point where commercial
adoption would rapidly increase, essentially baselining the cost.

Last year we put out a call for abstracts for presentations for our sessions Geosimulations for Addressing Societal Challenges.

These need to be directly fed into policy. We, as a Geosimulation community, have the skills and knowledge to use the latest theory, models and evidence to make a positive and disruptive impact. These include agent-based modeling, microsimulation and increasingly, machine learning methods. However, there are several key questions that we need to address which we seek to cover in this session.

How can we make sure they are robust enough to be used in decision making? How can...

A few weeks ago, I posed a simple yet thought-provoking question to the geospatial community on LinkedIn, one that many found difficult to answer, including myself:
In the past I have blogged about disasters, but mainly from a social media or agent-based modeling perspective. However, after the devastating wildfires that impacted parts of Los Angeles County earlier this year led me to wonder how resilient are cities to such events? Or more generally, what role could urban analytics play on the various stages of disaster management (i.e., preparation, response, recovery, and mitigation), or how can data, models, and methods at the disposal of researchers be leveraged to better prepare us for future disasters and be linked to policy?If these questions sound of interest, I encourage you to go and read a short editorial that I recently published in Environment and Planning B entitled "Cities and Disasters: What can Urban Analytics Do?"Full referece: Crooks, A.T.

OK, it has been a while since the last time I published this data, but I have a valid excuse.
The most striking feature of the 2024 chart is the zero’ing out of IBM’s piece of the pie. Big Blue, which once billed the government $107M in a year, has been reduced to a billing rate of less than $5M per year over the last two years.
Everything else feels more or less the same. After seven years of NDP government, the overall trajectory of outsourcing growth has beeen flattened, but in no way reversed. It is a smaller proportion of overall spend, but the substantial change wrought by the Campbell Liberal government starting around 2005 has been durable – BC IT has a huge outsourced component still.
The initial surge in smaller local companies after 2017 stalled out by 2021 and had been flat since.
The most consistent grower is now CGI, which entered the Victoria market around 2005 and has grown to $60M/year in billings with consistent year-over-year increases.

I recently “celebrated” my “cancerversary”, the one-year mark since my GI doctor phoned me up and said the fateful words – “you have cancer”.
At that moment, my universe shrank down immensely. All the external stuff, job, professional relationships, volunteerism, just kind of fell away, I had no mental space for it. It was just me and my immediate family and the many, many unknowns.
My experience since then has included two major physical insults. The “curative” surgery that removed most of my rectum, and the associated c.difficle infection that brutally wrecked my GI tract.
The insults really knocked me back. Moving around the house involved effort. Meals would lead to stomach pain and long sessions on the toilet. Runs were replaced with walks and then shorter walks. A trip to the cafe became my gold standard for “getting out”.

Every year, around 1.3 billion tons of food – nearly a third of total global food production – goes to waste (FAO). At the same time, 733 million people faced hunger in 2023, with one in five affected in Africa (WHO). It’s a painful paradox: tons of food are thrown away while millions go without.

We are delighted to announce a special track on “Integrating Large-Language Models and Geospatial Foundation Models to Enhance Spatial Reasoning in ABMs” as part of the Social Simulation Conference 2025, 25th to 29th August 2025 at Delft University of Technology, the Netherlands. Full conference details can be found at the end of this email.Abstract for the Special Track: Recent developments in the use of large language models (LLMs) offer exciting opportunities to control agent behaviour in potentially more realistic and nuanced ways than has previously been possible. However, an LLM-backed agent can only interface with their surroundings through text prompts, which is severely limiting. The integration of large language models (LLMs) and geospatial foundation models (GFMs) presents an exciting opportunity to use AI techniques to advance agent-based modelling for spatial applications, potentially allowing for agents with more comprehensive behavioural realism, as well as an improved...

A funny thing happened when I wrote up my 2025 book list – a lot of the books were parts of pairings. And I started wondering what other pairings I had read that were memorable.
So here’s another list!
Wicked, Gregory Maguire and The Wonderful Wizard of Oz, L. Frank Baum
You wouldn’t know it to look at me (or would you?) but I am a person who has read all 14 books of the original L. Frank Baum Oz series. From “The Wonderful Wizard of Oz” to “Glinda of Oz” and all in between.
As… that kind of person, I was truly tickled to pick up “Wicked” a couple years ago and take in not only the invented back-story of the Wicked Witch of the West (Elphaba), but also all the references to the Oz world that Maguire builds into his narrative. “Wicked” is the best kind of reimagining, one that manages a completely fresh story, but without tearing down the original source material on the way. Maguire clearly is also… that kind of person, and he treats Oz with respect while building a totally fresh...

Seven months ago, we issued A Call to Action for the Data Community to break down geospatial data silos and make GIS a core part of analytics. Today, we’re thrilled to announce two major developments that bring this vision closer to reality:
The Parquet specification has officially adopted geospatial guidance, enabling native storage of GEOMETRY and GEOGRAPHY types
Iceberg 3 now includes GEOMETRY and GEOGRAPHY as part of its official specification
Now both Parquet and Iceberg support columns of type GEOMETRY or GEOGRAPHY just like INT32, INT64, FLOAT32, etc. columns! Yay! This is a landmark achievement for geospatial data! 🎉

For PostGIS Day this year I researched a little into one of my favourite topics, the history of relational databases. I feel like in general we do not pay a lot of attention to history in software development. To quote Yoda, “All his life has he looked away… to the future, to the horizon. Never his mind on where he was. Hmm? What he was doing.”
Anyways, this year I took on the topic of the early history of spatial databases in particular. There was a lot going on in the ’90s in the field, and in many ways PostGIS was a late entrant, even though it gobbled up a lot of the user base eventually.
This blog post was first published on Chris’ personal blog on February 9, 2025 and is being cross posted here.

In previous posts we have noted how one can explore urban issues through newspapers, while at the same time we have used social media to explore trends in vaccinations. In a recently published paper in PLOS Digital Health entitled "From print to perspective: A mixed-method analysis of the convergence and divergence of COVID-19 topics in newspapers and interviews" with Qingqing Chen, Adam Sullivan, Jennifer Surtees, Laurene Tumiel-Berhalter and myself, we thought we would explore how COVID-19 was reported in newspapers and how this varied from interviews. The rationale behind this was that the COVID-19 pandemic has led to diverse experiences influenced by public health measures like lockdowns and social distancing. To explore these dynamics, we introduce a novel ’big-thick’ data approach that integrates extensive U.S. newspaper data with detailed interviews. By employing natural language processing (NLP) and geoparsing techniques, we identify key topics related to the pandemic and...
Cloud-Native Geospatial represents a significant shift in how geospatial data is processed, stored, and analyzed. This approach offers GIS Professionals greater scalability, allowing them to handle massive datasets without relying on traditional and often limited on-premise infrastructure. Additionally, the cloud-native approach enhances collaboration by enabling multiple users to access and work on shared datasets in real-time, regardless of their physical location, helping to eliminate data silos. This level of accessibility and flexibility empowers GIS professionals to deliver faster results, streamline workflows, and adapt to the growing demands of modern geospatial applications.
What is Cloud-Native Geospatial?
Cloud-native geospatial refers to the practice of leveraging cloud-based technologies and architectures to handle geospatial data in the cloud, ideally without migrating it between heavy/purpose-built storage and file formats. This approach focuses on...
Following up on my last post, I wanted to share some more details about the experience of using AI tools to code a plugin for QGIS, one that has seen some reasonable success, with over 2000 downloads in the past couple of months. My hope is to inspire others to make their own QGIS plugins and other geospatial tools, as I think more people doing AI-assisted coding has the potential to accelerate the momentum of the open source ecosystem.

You can code a QGIS plug-in even if you’re not a software developer. I’m sure you’ve seen the videos of people building cool things with AI tools, but it can still be hard to actually dive into it. For me the most important thing is to have a real problem you’re...

I have been watching the codification of spatial data types into GeoParquet and now GeoIceberg with some interest, since the work is near and dear to my heart.
Writing a disk serialization for PostGIS is basically an act of format standardization – albeit a standard with only one consumer – and many of the same issues that the Parquet and Iceberg implementations are thinking about are ones I dealt with too.
Here is an easy one: if you are going to use well-known binary for your serialiation (as GeoPackage, and GeoParquet do) you have to wrestle with the fact that the ISO/OGC standard for WKB does not describe a standard way to represent empty geometries.
Empty geometries come up frequently in the OGC/ISO standards, and they are simple to generate in real operations – just subtract a big thing from a small thing.

Last month I released my first QGIS plug-in, and promised I’d write an in-depth post about it. I’ll give an overview and dig into some of the motivations, and then I’ll put the details of my experience of coding with AI in its own follow up post.
Background
I’ve been a long time QGIS user, though am very far from an expert — I mostly open different files and visualize them. I’ve never been able to afford an Esri license, so it’s QGIS all the way for me. And I’ve always loved the plugin ecosystem: the fact that many people worldwide are adding all kinds of functionality so that anyone can customize it to their needs is just awesome, and a testament to the power of open source. There’s still things Esri can do better, but we’re now at the point where there’s a lot of things QGIS can do better.

In previous posts, we have written how large language models (LLMs) like ChatGPT can be used in various urban analytical applications. We have kept exploring this potential especially with respect to citizen science applications. To this end we have just published a new paper in iScience, entitled "New Directions in Mapping the Earth’s Surface with Citizen Science and Generative AI". In the paper, lead by Linda See, we discuss how multi-modal LLMs (MLLMs) which are like LMMs but can take different forms of inputs (e.g., text, images, video) and output multi-modal information (e.g., take an image and output a description) could be leveraged to enhance citizen science land cover/land use mapping campaigns.

A goal for me this year is to ‘ship more’, so in the spirit of releasing early and often I wanted to share a little new project I got going this past weekend. See https://github.com/cholmes/geoparquet-tools.
It’s a collection of utilities for things I often want to do but that aren’t trivial out of the box with DuckDB. It started focused on just checking GeoParquet files for ‘best practices’, which I’ve been working on writing up in this pull request, as I realized that lots of people are publishing awesome data as GeoParquet but don’t always pick the best options (and the tools don’t always set the best defaults). So it can check compression, if there’s a bbox column, and row group size. It also attempts to check if a file is spatially ordered, but I’m not sure if it works across different types of approaches. It does seem to work with Hilbert curves generated from DuckDB.
I do need to refine the row group...
DuckDB continues to be my go to tool for geospatial processing, after I discovered it over a year ago. Since that time its functionality has continued to expand, and as of version 1.1 it reads and writes GeoParquet natively, as long as you have the spatial extension installed.
LOAD spatial; CREATE TABLE fields AS (SELECT * from 'https://data.source.coop/kerner-lab/fields-of-the-world-cambodia/boundaries_cambodia_2021.parquet'); COPY fields TO 'cambodia-fields.parquet';
Be sure to always run LOAD spatial; or the table won’t get a geometry column, it will just create blobs. If you see errors or your output data is just Parquet and not GeoParquet that’s likely the source of your problems. I often forget to add it at the beginning of my sessions — perhaps there is some nice way to configure DuckDB to always load it, but I don’t know it (yet).
I also do recommend that you always use zstd compression, as it generally results in at least 20% smaller files, and its speed is...

I did a lot of reading last year, a lot, perhaps because I had a lot of down time. I tend to read before going to sleep, and recovery from surgery and other things means I go to bed early and then fill the time between bed and sleep with books. Books, books, and more books.
To be totally precise, I read books on a Kindle, which allows me to read in the middle of the night in the dark with the back light. Also to read from any position, since all books are the same, light weight when consumed via an e-reader. I am a full e-reader convert.
Anyway, I’ve had means, motive and opportunity, and I read a tonne. Some of it was bad, some of it was good, some of it was memorable, some not. Of the 50 or so books I read last year, here are ten that made me go “yes, that was good and memorable”.

As the holiday season wraps us in its warm embrace, we at T-Kartor can't help but reflect on a year filled with challenges, triumphs, and moments that made our hearts grow.
This past week we attended the American Geophysical Union (AGU) Fall Meeting in Washington DC. At the AGU we presented two abstracts. The first follows on our work with respect to using synthetic populations within agent-based models. This work was with Na Jiang, Fuzhen Yin and Boyu Wang and entitled "A Framework for Populating Urban Digital Twins with Agents." Or more specially why digital twins need agents. Below you can see our abstract and a couple of figures showing our synthetic population workflow and how we integrate these into agent-based models. Abstract:Over the last few years, considerable efforts have been placed in creating digital twins from diverse fields ranging from engineering to urban planning and many things in-between. These digital twins have benefited from the growth and availability of computational power and data. For example, in urban planning the growth of computational resources and the explosion of spatial data sources(e.g. remote sensing) has lead to...

You’ve spent years figuring out how to visualize large geospatial datasets in web browsers. Can you tell us a bit about your background and what initially drew you to this area?
I have a bit of a nontraditional background; I have virtually no official training in geography or computer science.

In numerous posts, we have been discussing synthetic populations and their use in agent-based modeling. But there are many modeling styles that also utilize synthetic populations. In our own work we often spend significant amounts of time creating such synthetic populations, especially those grounded with data, due to the time needed to collect, preprocess and generate the final synthetic population. To alleviate this, we (Na (Richard) Jiang, Fuzhen Yin, Boyu Wang and myself) have a new paper published in Scientific Data, entitled "A Large-Scale Geographically Explicit Synthetic Population with Social Networks for the United States." Our aim of this paper is to build and provide a geographically explicit synthetic population along with its social networks using open data including that from the latest 2020 U.S. Census which can be used in a variety of geo-simulation models.Summary of the Resulting Datasets.Specially, in the paper we outline how we created the a synthetic population...

While in the past we have written about how we can use agent-based models to capture basic patterns of life, and even developed a simulations, but until now we have never really demonstrated how we go about this. However, at the SIGSPATIAL 2024 conference we (Hossein Amiri, Will Kohn, Shiyang Ruan, Joon-Seok Kim, Hamdi Kavak, Dieter Pfoser, Carola Wenk, Andreas Zufle and myslf) have a demonstration paper entitled "The Pattern of Life Human Mobility Simulation." in which we show: How to run the Patterns of Life Simulation with the graphical user interface (GUI) to visually explore the mobility patterns of a region.How to run the Patterns of Life Simulation headless (without GUI) for large-scale data generation.How to adapt the simulation to any region in the world using OpenStreetMap data,Showcase how recent scalability improvements allow us to simulate hundreds of thousands of agents.If this sounds of interest, below we show the GUI to the model, along with the steps to generate a...

In the past we have written about the use of synthetic populations and their use in agent-based models. We are finding such synthetic populations to be extremely useful in the creation or initialization of agent-based models. To give you a sense of how we are utilizing such synthetic populations at the 7th ACM SIGSPATIAL International Workshop on Geospatial Simulation (GeoSim 2024), Na (Richard) Jiang and myself have a new paper entitled "Studying Contagious Disease Spread Utilizing Synthetic Populations Inspired by COVID-19: An Agent-based Modeling Framework." In the paper we show how we can we utilize a method to create the geographically-explicit synthetic population along with capturing their social networks and how this can be used to study contagious disease spread (and various lineages of the disease) in Western New York.

In the past we have explored how agent-based modeling can be used to study vaccine uptake and what is the mechanism underlying the diffusion of different vaccine opinions in hybrid spaces (e.g., physical, relational and cyber) can affect individuals’ vaccination decisions. But this prior work was limited to just one small area. However, we know that urban and rural communities have different levels of digital connectivity and we were wondering if our initial findings are applicable to other counties which are more urban or to a larger study area. To explore this, at the 7th ACM SIGSPATIAL International Workshop on Geospatial Simulation (GeoSim 2024) we (Fuzhen Yin, Na Jiang, Lucie Laurian and myself) have a paper entitled "Agent-based Modeling of COVID-19 Vaccine uptake in New York State: Information Diffusion in Hybrid Spaces". This paper significantly extends our previous work in a number of ways. First we move from a single rural county to the entire state of New York which has...

The effects of educational attainment on individuals and society have been the subject of much research. However, there is still a need to study what factors matter the most, and what is worth investing more time and resources into, and how new methods of analysis can provide additional ways of looking into some of the challenges faced by higher education. To this end at the 2024 International Conference of the Computational Social Science Society of the Americas (CSSSA), Amira Al-Khulaidy Stine and myself had a paper entitled "Retention in Higher Education: An Agent-Based Model of Social Interactions and Motivated Agent Behavior." In the paper we introduce an agent-based model which explores retention where we focus on students and their levels of motivation (i.e., "grit"), their immediate connections (i.e., sense of belonging) and institutional support. At the same time we capture institutional locales (i.e., urban and rural) and their selectivity. Taken all together the model...

I was glancing at the New York Times and saw that Catherine, the Princess of Wales, had released an update on her treatment. And I thought, “wow, I hope she’s doing well”. And then I thought, “wow, I bet she gets a lot of positive affirmation and support from all kinds of people”.
I mean, she’s a princess.
Even us non-princesses, we need support too, and I have to say that I have been blown away by how kind the people around me in my life have been. And also how kind the other folks who I have never really talked with before have been.
I try to thank my wife as often as I can. It is hard not to feel like a burden when I am, objectively, a burden, no matter how much she avers I am not.

What happened there, I didn’t write for three months! Two words: “complications”, and “recovery”.
In a terrifying medical specialty like cancer treatment, one of the painful ironies is that patients spend a lot of time suffering from complications and side effects of the treatments, rather than the cancer. In my case and many others, the existence of the cancer isn’t even noticable without fancy diagnostic machines. The treatments on the other hand… those are very noticable!
A lot of this comes with the territory of major surgery and dangerous chemicals. My surgery included specific possible complications including, but not limited to: incontinence, sexual disfunction, urinary disfunction, and sepsis.
Fortunately, I avoided all the complications specific to my surgery.
What I did not avoid was a surprisingly common complication of spending some time in a hospital while taking broad spectrum antibiotics–I contracted the “superbug” clostridioides difficile, aka...

We are proud to announce the final release of STAC 1.1.0.
The focus has been the addition of a common band construct to unify the fields eo:bands and raster:bands. Additionally, Item Asset Definition (field item_assets) - formerly a popular STAC extension - is now part of the core specification. Various additional fields have been made available via the common metadata mechanism, e.g. keywords, roles, data_type and unit. We collaborated closely with the editors of OGC API - Records to align better with STAC, which resulted, for example, in a change to the license field. The link object was extended to support additional HTTP mechanisms such as HTTP methods other than GET and HTTP headers. The best practices have evolved and various minor changes and clarifications were integrated throughout the specification.

This post introduces STAC GeoParquet, a specification and library for storing and serving SpatioTemporal Asset Catalogs (STAC) metadata as GeoParquet. By building on GeoParquet, STAC GeoParquet makes it easy to store, transmit, and analyze large collections of STAC items. It makes for a nice complement to a STAC API.
STAC Background
STAC makes geospatial data queryable, especially “semi-structured” geospatial data like a collection of cloud-optimized GeotTIFFs (COGs) from a satellite. I can’t imagine trying to work with this type of data without a STAC API.
Concretely, STAC metadata consists of JSON documents describing the actual assets. STAC metadata can typically be accessed in two ways:
Through a static STAC catalog, which is just a JSON document linking to other JSON documents (STAC Collections and / or STAC Items, which include the links to the assets)
Through a STAC API, which also enables things like search.
In practice, I haven’t encountered much data...
