OpenStreetMap Blogs - Customizing MapLibre Navigation Control for Different Devices and Screen Sizes
You can find a German version of this article here: Navigation Control oder Zoom Control in MapLibre
In this post, I’m considering how to customize the Navigation Control and Zoom Control in MapLibre for different scenarios—such as depending on whether a pointer is available or the size of the screen. I’m also wondering whether CSS or JavaScript would be the better approach.
My goal is to display the Navigation Control only on devices where it makes sense and provides a good user experience. Since I’m new to this topic, I welcome any thoughts, feedback, or suggestions for improvement.
Navigation Control or Zoom Control in MapLibre
I’ll start with a simple example:

Long time OSM user and occasional contributor, I recently found out that I can import bus stops from the operator* data for the area of Grenoble, France. For the moment I just want to import stop points which don’t exists in OSM.
I described all the process in this wiki page and, as it seems that mass imports are not always a good idea, I’d be happy to read any comment or tips ! I am currently discussing with locals contributors and doing some tests import on the dev server

About us
The OpenStreetMap (OSM) ecosystem is very vast, making it complicated to investigate user preferences for OSM-related software or topics. A Keynote will be presented by Raquel Dezidério Souto at the State of the Map 2025, in English, showing the development of a study on the publication profile of the weeklyOSM, analyzing the content of the issues published on the last ten years (numbers 272 to 768), since it began to be organized with the OpenStreetMap Blog Collector (OSMBC), created by TheFive. The self-organized session is scheduled to Saturday, October 4th, 2025, 10:30 – Manila Time (UTC+8). This research was previously noticed by us in the numbers #783 and #769.

Altweibersommer bezeichnet eine meteorologische Singularität Ende September
oder Anfang Oktober, die durch ein warmes Ausklingen des Sommers
gekennzeichnet ist. So legten wir das FOSSGIS-OSM-Communitytreffen Nr. 24
auf das vorletzte Septemberwochenende (19.-21.09.2025) und wurden
mit zwei wunderbaren Spätsommertagen belohnt. Wegen der zeitlichen Nähe zu
anderen Veranstaltungen wie der FOSSGIS-Jubiläumsfeier fand das Treffen diesmal
in kleinerem Kreis mit 13 Übernachtungs- und vier Tagesgästen statt.
Nichtsdestrotrotz war auch dieses Treffen wieder sehr produktiv. Die diskutierten
Themen reichten von der Langzeitarchivierung von OSM-Daten durch Bibliotheken
über OpenStreetMap bei Jugend Hackt, der Nutzung freier OpenSourceSoftware
ohne Wartungsvertrag, dem Mapping von Schulen bis hin zum Kartendruck aus
OpenStreetMap-Daten. Auch FOSSGIS-Vereinsthemen wie die Vorbereitung
der FOSSGIS-Konferenz 2026 und Presse- und Öffentlichkeitsarbeit kamen nicht zu kurz.

In the English Channel, technically outside of the UK, there are the Crown Dependencies of Jersey and Guernsey. Aside from the main island of Guernsey there are three related islands: Alderney, Herm, and Sark. I visited the latter two by ferry earlier this month.
You can find plenty of travel photos of these places, so I will try to focus on the niche topics of mapping and car-free communities.
Herm is the smaller island with ~60 permanent residents. They have even banned bicycles? I had two hours and mapped a newer business and a sculpture near the quay. There is a one-person hut with a sign saying it’s their jail/gaol - I wasn’t sure if it was a joke?
One of the boat landing sites was a bit precarious:
Sark has a larger area and population (~500), and still operates without cars. Tractors meet the boat. One pulls a streetcar ‘Tractor Bus’ up the hill. Any visit by a politician, celebrity, or royal will be sure to mention how they get from the harbor into town.

Tokyo’s train stations are famous for their departure melodies - short musical jingles that play when a train leaves a station. Each station on the city’s extensive rail network has its own distinctive tune, creating a unique soundscape that signals the start of a journey. These melodies are designed to soothe passengers, catch attention, and add a touch of local character to the daily commute.

Our OpenStreetMap interview series continues, this time we again learn about a regional OpenStreetMap community.
It was my pleasure to speak with Thibaut Maïto, an active member of the community in Lyon, France, a group that s very active on mastodon as @osm_lyon, which is how we came into contact.
1. Who are you and what do you do? What got you into OpenStreetMap?
Hi, I’m Thibaut MAÏTO, alias Thibtib51 on OpenStreetMap. I’m an electronic technician, and I discovered OSM during an electronic job involving geospatial equipment (working for one of the bigger instrument builder with a T in the trademark) in 2018. So I came to the project a bit later than others. In the beginning I used OSM data on the data collectors of the geospatial’s equipment. The detail was great, and I learned of this “map” around me and saw the power of details in comparison with another map (starts by G).
After a while I started to improve the map around me, for a lot of topics: road, building,...

I’ve been a geography nerd for my entire life. Recently, I’ve gotten into OSM as part of my need to map bike lanes for an advocacy article on bike lanes.
Initially, I mapped manually using Mapbox studio. Yes, it was tedious.
A bit more research led to OSM. I checked ways to pull down bike lane tags.
That led me to the world of OverpassQL, with Overpass Turbo and the Overpass API. Along the way, I also got a taste of tagging with the need to find bike related infrastructure. Apparently, all the tags here apply:
bike=
cycleway=
cycleway_left=
cycleway_right=
cycleway_both=
Quite fun.
I managed to put my query together. Google Gemini search AI tried to be helpful with query suggestions. It was of limited accuracy.
After realizing that some infrastructure was missing, I had to consider maintenance of my underlying data. With OSM being an open source project, I decided to become a contributor.

A successful crop forecast is fundamentally dependent on the quality of the agriculture data used to build it, from geospatial data and crop imagery to agricultural statistics. High-quality data must be structured, timely, and comprehensive, integrating multiple sources like soil conditions, weather, and crop health metrics. Ultimately, leveraging this high-quality data allows farm managers and agronomists to make sharper, more profitable operational decisions and achieve a new level of control.

There are a number of ongoing discussions about the geocoder on osm.org (Nominatim) in the forum at the moment. These include spelling tolerance, how it might work with data that does not exist in OSM yet and what it actually returns.
Sometimes the results of the last of those can be a bit odd. Here for example is a post office not far from me. The returned data (“Stillington Post Office & Stores, Main Street, Stillington, York, North Yorkshire, York and North Yorkshire, England, YO61 1JS, United Kingdom”) has three things that could plausibly be a county in there - York itself, North Yorkshire, and York and North Yorkshire. In OSM these are respectively a nearby place=city node, and encompassing admin_level=6 and admin_level=5 relations.
The problem here is, like in the case of the Northern Irish super-councils mentioned in the forum, the data returned by Nominatim does match administrative areas but doesn’t entirely match places that people associate themselves with. ...

If there’s one thing people who know me will say, it’s that I’m a proud Lokeraar through and through. The history of Lokeren, and the way the city keeps changing, has always fascinated me.
It all started in 2019 when I began editing Lokeren’s Wikipedia page. I wanted it to be more than just a dry article—I wanted it to reflect the city’s character with accurate and engaging information. After two years of expanding and polishing, I felt I had done my part there, and I started looking for other ways to put Lokeren on the map.
That’s when I discovered OpenStreetMap in 2021. My first edit was just a tiny stream in Lokeren. But from that small start, it turned into a real passion. Before long, I was mapping everything: trees, bike paths, parking lots, even new buildings as they appeared.
Now, four years later, I can proudly say the mission has been a success so far. But it doesn’t stop here—Lokeren keeps growing, and so does my map. And honestly, that’s the best part: there’s...

This is the story of how I mapped the islands off the west coast of the Korean Peninsula. The story began on July 24th (two months ago). I thought long and hard about what mark I should leave on cartography, what was within my capabilities? And the task that seemed feasible to me was to map the islands of South Korea. TTheir number is limited, and the territory between them is much smaller than on the mainland. So, I realized it was a realistic task. All that remained was to find a way to start. I needed not the smallest, but not the largest island either, something that would be a great start. And so I selected the islands of the 영흥면: 영흥도, 선재도, 측도, 부도 and about a dozen more less significant ones.
I did all the work using an ID editor. My skills at the beginning were extremely mediocre, but I learned a lot along the way.

Unfortunately, when I started working on the islands, I didn’t realize I’d have to write a report in the future. So I didn’t think to save an...

Background
In 2023, New Brunswick (Canada) underwent a province-wide restructuring of their municipal boundaries. This consisted of 77 Incorporated Municipalities and 12 Unincorporated Rural Districts. Between 2023 and 2025, only a small handful of these boundaries were actually imported into OSM. Thus, I took it upon myself to begin what was my largest project ever, a full import of the updated boundaries across the province.
I saw it fit to write up a post summarizing the work that was done, along with some of the rationales for certain tagging methods used in this project, in order to maintain consistency both now and into the future. It should be noted that this was not an automated import, every kilometer of boundary was manually reviewed. The data used was from GeoNB, under the Open Government License – New Brunswick.

When I started this project, New Brunswick’s existing boundary data was a complete mess, some larger cities had...

As I’m interested in pedestrian infrastructure, I asked myself what percentage of all sidewalks in Germany has already been mapped.
It is difficult to answer this question because I do not know the total number of sidewalks in Germany. However, it is possible to change the question slightly to make it easier to answer: How many streets in Germany contain information about the presence of sidewalks?
This is easier to answer, because we can assume that all streets of Germany have already been mapped. Therefore, to answer the question, we just have to count the streets that contain the desired information.
Sidewalk tags
Currently, four tags are in use for mapping sidewalks: sidewalk, sidewalk:left, sidewalk:right and sidewalk:both. The tag sidewalk was introduced around 2010 and is still widespread, accounting for around 80% of all sidewalk tags:
The other three tags were added in January 2021. Normally sidewalk:left and sidewalk:right should be used together to provide a...

Piloting technology is the smartest way to approach construction technology adoption. By using a construction reporting app to capture accurate construction data and streamline every construction field report, teams can test workflows, validate integrations, and build trust with crews before scaling. The result is adoption that feels controlled, measurable, and repeatable across projects while reducing risk, saving costs, and proving ROI in construction technology adoption.

In our ongoing series on geospatial raster data formats, Julia
Signell and I have been exploring the
finer points of array data storage. Throughout our research, we’ve found that
chunking – breaking a large dataset down into smaller pieces for individual
storage and retrieval – is universally relevant regardless of data format.
Chunking, as we’ve seen, is an absolutely necessary strategy for making large
datasets usable, but in the cloud era, it has become something
tyrannical,
making data access efficiency strictly tied to chunk alignment.
Diverging from an access pattern aligning with the dataset’s chunking scheme and
compounding inefficiencies will cripple data access at scale. Pretend, for

This afternoon, while pondering and daydreaming about seriously quitting OSM for real, I ventured into the land of Wikimapia.
Then I stumbled upon a conversation between high-ranking admins over there.
“Why did you delete a number of TNB sub-stations from the map? Don’t you think those tags were useful, to some people at least? I think the user(s) who initially created those tags put a lot of effort in detailing the model nos., etc. for some of the sub-stations. Thanks.”
“The TNB sub stations is not a place. It just an OBJECT just like small bridges, security guard post, small jetty etc. Different with a PLACE such as Pulau Pinang Bridge or any big bridges, police station or a port such as Port Kelang. As you can see there are few users that like to tag a small roadside stall and a small public toilet. That also is in the list for deletion. You must know to differentiate what can be tag and what can’t.”

One of the trickiest challenges in OSM is when a river (or any linear water feature) doubles as a regional or administrative boundary.
Rivers shift course over time; floods, erosion, and meanders, while boundaries often remain legally fixed. The result? Misalignments, overlapping lines, or confusing gaps on our maps.
For many contributors, editing such overlaps is daunting. Boundaries are sensitive, technically complex, and mistakes can cause big issues. Yet, leaving them mismatched affects disaster planning, legal clarity, and overall map quality.
My Question to Experienced Mappers 🙏
How do you decide whether to follow the legal boundary or the current river course?
Rivers don’t wait. Boundaries don’t move. But as mappers, we can bridge the gap. I’d love to hear your experiences and solutions!

While working on an OSM-related statistics project that I need to present in the next few months, I stumbled across some ‘conversations of the past,’ scattered in changeset comments and block reports.
Some of those conversations triggered a strong emotional response in me—so much that I had to pause for a quick breather. I think I’ve just been exposed to a serious infohazard.
Then I remembered “that page” on Wikimedia Meta-Wiki.
Wikistress is stress caused by activity on a wiki like Wikipedia such as conflict, vandals, trolls, edit wars, and incivility.
I’ve suffered this kind of stress several times on Wikipedia, and now—since OSM is by nature quite similar to Wikipedia—I’ve relapsed again.
By the way, on that page, there are several tips for dealing with personal wikistress. I think we can adapt those tips to the OpenStreetMap context.

Land subsidence threatens safety, compliance, and productivity across mining operations. Reliable GIS field data in mining ensures that every observation, from surface cracks to elevation shifts, flows into models that guide risk detection and response. Structured field measurements provide the foundation, while remote sensing, satellite imagery, and digital elevation models (DEMs) add the broader context needed to keep subsidence models accurate. Digital platforms tie these inputs together in real time, turning raw field observations into actionable strategies for safer, more resilient operations.

the brutal life of a survey party, and the elegant science of triangulation

Reliable GIS starts with field mapping workflows designed for accuracy from the outset. These workflows keep field data and real-time data in sync with web maps and feature layers so spatial data stays trustworthy from collection to decision. By combining automatic GPS tagging, in-field validation, and mobile tools that streamline data capture, teams produce consistent data that drives dependable maps and actionable insights. With better data capture and digital workflows, projects stay accurate without wasted effort in the field.

Fulcrum - Data-driven resilience planning: Why better field workflows lead to smarter infrastructure
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.

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.

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...

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

I have just gotten back from attending the 19th International Conference on Computational Urban Planning and Urban Management (CUPUM) in London and thought I would share the two papers we presented at the conference. 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. If this sounds of interest, below you can see the abstract to the paper, some if the figures (i.e., the work flow and prompts) while the results can be seen in the attached paper (see the link below).

Join us at ESA Living Planet Symposium 2025 to build, explore, and reimagine EO workflows together.
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.

Last week, Switzerland’s Birchgletscher collapsed and caused a major rock avalanches, altering the landscape and burying the village of Blatten. With the data of the federal Rapid Mapping service and the help of individual experts, a first open post-event elevation model was made available. I used the model to create pre- and post-event visualizations and prints at a local scale.
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...

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

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.

First up (in order in which they were presented) was "Utilizing Streetview Images for Mapping Building Attributes with ChatGPT" with Qingqing Chen and Linda See. In this talk we discussed how multimodal Large Language Models are giving us a new way to study cities, in the sense, lowering the boundary for information extraction. Using ChatGPT and street view images from Mapillary as an example, we showed how one can extract building age, usage (e.g., commercial, mixed use, residential) and estimate building height which could all be used to inform urban climate models which...

Last year we put out a call for abstracts for presentations for our sessions Geosimulations for Addressing Societal Challenges. The session description is as follows: There is an urgent need for research that promotes sustainability in an era of societal challenges ranging from climate change, population growth, aging and wellbeing to that of pandemics. 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. For example, What do we need to be able to contribute to policy in a more direct and timely manner? What new or existing research approaches are needed? How can we make sure they are robust enough to be used in decision making? How can...

Geospatial technology is the modern expression of geography, encompassing geographic information systems, remote sensing, and surveying technology. “Geospatial technology” is a convenient catch-all term for anything with a location component. The problem is that geography is quite literally everywhere, and modern geospatial technology is, in fact, changing everything.

Cloud-Native Geospatial is quietly revolutionizing geospatial data
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:
Sorry, this entry is only available in French.
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.

Simple facts about the new Cloud-Native Geospatial hype.
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”.
Now, I am immensely “better” than I was this summer. But I am still a very long way from the physical condition I was before (which was...

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...

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...

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.

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.

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.

When maps understand what you mean, not just what you click
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...
The post Tech Fellow Update: Exploring Field Boundary Data with LLMs appeared first on Taylor Geospatial Engine.
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 college, I was interested in urban and environmental economics, trying to understand how policies shape cities and the environment. I planned to pursue a PhD in economics and after college worked for a health economics professor at MIT for two years.
In that time I learned data analysis skills, but more importantly, I learned that I preferred data analysis and coding to academic research. I decided not to pursue a PhD and left that job to hike the Pacific Crest Trail, a 2,650-mile hiking trail from Mexico to Canada through California, Oregon, and Washington. Over five months...

Keeping geospatial professionals informed on the legal and policy issues that will impact GeoAI.
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...

These systems are not just about understanding our present but about anticipating our future—guiding us safely and sustainably through the challenges ahead.
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. If this sounds of interest, below you can read the abstract from the paper, see some of the results and find the full reference and the link to the paper....

Just a quick post, In recently released Encyclopedia of Human Geography edited by Barney Warf we were asked to write a short chapter entitled "Agent-based Models and Geography" In the chapter we discuss how over the last several decades, agent-based modeling has gained widespread adoption in geography.and introduce the reader to what are agent-based models, how they have developed and types of geographical applications that can be explored with them, especially when linked to Geographical Information Systems (GIS). The chapter concludes with a brief summary along with a discussion of challenges and opportunities with agent-based modeling (ABM).

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...
