This is New Amsterdam in 1660, when Peter Stuyvesant was serving as the director-general of the colony of New Netherland. New Amsterdam, located on the southern tip of Manhattan Island, was the capital of New Netherland.One of my favorite interactive maps of all time is the Beyond Manhatta. This project visualizes Manhattan Island and its native wildlife, as it would have looked in 1609.

Imagery Offset Database Todo mapeador aficionado debería saber que todas las imágenes obtenidas de forma remota (por ejemplo, imágenes satelitales y fotografías aéreas) y otras fuentes, excepto las trazas GPS, suelen estar mal alineadas con respecto a la realidad. Como resultado, el cartógrafo debería poder alinear las imágenes en su editor preferido utilizando trazas GPS. El proceso lleva entre 5 y 10 minutos y, debido a la precisión del GPS, los resultados varían. No es tan malo si eres el único cartógrafo en cientos de kilómetros a lo largo de cientos de años, pero para la cartografía cooperativa, incluso una variación de un metro importa. Un análisis del problema reveló dos posibles soluciones, ambas igualmente efectivas. La base de datos de desplazamientos y el complemento de desplazamientos implementan ambas; no se excluyen, sino que se complementan entre sí, lo que permite al mapeador verificar los desplazamientos no solo con trazas GPS, sino utilizando un método de...

Some days ago, I searched online for a bus route that was supposed to be newly introduced to go from Kilkenny to New Ross. I didn’t find it, but I found another one which pleased me even more which goes from Kilkenny to Fiddown (ref=891). The reason it pleases me is that the other route is already partly covered by another bus company and I don’t really need it, and the 891 covers a route that goes past several historical sites and at least two hiking routes. Since I don’t drive, I will certainly avail of it myself. I don’t mind organizing myself lifts, and I enjoy the company of my “drivers”, but sometimes it’s good to be more independent. For context, the bus route started on January 20th 2025.

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.

About Me I have been a member of OpenStreetMap US for five years, engaged in fostering open data and community collaboration. My first experience with OpenStreetMap was while working in emergency management in 2010 when the Haiti earthquake occurred. As someone trained in disaster response, I watched the events in Haiti unfold and looked for ways to contribute. It was also my gateway into other open data & software communities, such as QGIS and OSGeo, which informed my educational approach during my time at the University of Arizona Libraries. I helped host the first MappingUSA virtual conference and, in 2022, hosted the State of the Map US conference at the University of Arizona in Tucson, marking the first in-person gathering post-COVID.

About Me Hey folks! I’m Gregory Power (they/them) and I’ve been a part of the map since November 2023. I am currently a Data Scientist (Contractor) for Cary, North Carolina—where I manage Cary’s Open Data Portal and other analytics infrastructure. In my spare time I enjoy learning about urban planning and equitable, multimodal infrastructure. I’m also involved with the Pedestrian Working Group, Government Working Group, and my community’s Strong Towns chapter. I enjoy contributing to the open source geospatial software community, with a soft spot for GDAL, QGIS, GRASS GIS, and DuckDB—so everyone can have the tools to understand the world around them. Even though there’s a great set of tools for us to use, it’s nothing without having an open ecosystem of data.

This was harder than I thought it would be. The lesson for re-drawing a road was drag-and-drop. I could not insert an extra node in the Administrative Boundary in order to truncate the triangle. I had to create a new Administrative Boundary and relate it to the existing boundary. Then delete the node at the top of the old boundary. Requested review as I’m not sure that is the correct or accurate way to perform the task.

We are happy to announce the release of Nominatim 5.0.0. This major release marks the end of a 4-year journey to modernize and modularize the Nominatim codebase in order to make it easier to use and maintain. This release finishes the mutation of Nominatim into a Python package. The PHP frontend, bundled osm2pgsql and cmake build scripts have now been removed for good. If you are still using one of these features, then you should update your software to Nominatim 4.5 and then move to the new Python frontend and pip installation. Once done, you can easily update to the latest version 5 release. Also in this release, the osm2pgsql import style configuration has been largely be rewritten. If you are using one of the built-in styles, this will not make much of a difference. If you are maintaining your own custom style, however, this should become much easier. Most notable, it is now possible to start with one of the existing styles and add your customizations on top. That should...

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...

Hello! I’ve just found out that ~2k out of ~13M relations have no type tag, ~220 of which have the type tag with lifecycle prefix or date namespace suffix, so I’ve decided to review them manually, with the ones with no tags containing the word “type” being the first, correct some mistakes (e.g. missing type=multipolygon) and delete the unnecessary relations (e.g. with duplicate tags). In case I make a mistake, please point it out on OSM Community topic or comment my changesets. Regards Kamil Kalata

In the February 2025 edition of our interview series with OpenStreetMap communities around the world, we speak with open source geospatial software and OpenStreetMap veteran Just van den Broecke about the OpenStreetMap Alpumapa Workshop. 1. Who are you and what do you do? What got you into OpenStreetMap? Just van den Broecke from The Netherlands, a long-time open source geospatial professional. I wrangle geospatial data, a.k.a. ETL, work on geospatial web services like OGC REST APIs, and make maps like map5topo.nl, a topographic map of The Netherlands. Registered my OSM account ‘justb’ in 2005. Was then mapping inline skate-routes and contributed to hiking for years. Though I was not a very active mapper, I recently revived, also through this project and joining OSM-ES. 2. What is “Mapas y Tapas” in Alpujarra and why did you create it? Who participates? “Mapas y Tapas” is a free Spanish translation of “Mapping Party”. We are a group, now mainly around Ugíjar, that started...

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...

I’m happy to announce that I have been selected for the one-year pilot of the Sovereign Tech Fellowship programme of the Sovereign Tech Agency. The fellowship programme will support maintenance of Nominatim, Photon, osm2pgsql and pyosmium over the next year. Participating in an open-source software project like Nominatim or Photon is not just about the implementation of fancy new features or clever algorithms to improve performance or the user experience. A lot of work happens quietly behind the scene: user questions need to be answered and bug reports followed up. Dependent software needs to be monitored and updated as necessary. The own code needs to be reviewed and polished regularly to prevent it from ageing and slowly falling apart. CI pipelines are a great tool for a maintainer but they do break with an astonishing regularity and therefore need regular attention. Not to mention that a CI is useless without a set of well-maintained tests. With its new Sovereign Tech...

Panoramax is a rising star at the moment, for OSM, but not only; while Mapillary goes down, sold to Facebook. In my old www.OSMgo.org, the key P showed a Mapillary picture near the actual position in the 3D rendered OSM world. As the API is gone, I replaced it with Panoramax. OSMgo was abandoned by me years ago but the server is still running. As I read more and more about Panoramax, I decided to dig out the old code and use it. First I asked in the Fediverse for help with the API and got a great and fast response, even a good example, thank you all!

 There are almost to much pages about it. The real API was a bit hidden but well documented at last. The Idea of decentralised servers but a central directory is great, the Web-UI to see all pictures to. And the API got me a json list of the closest pictures, including a link to the pictures.

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. Cursor & QGIS — awesome together :) Can you really code a QGIS plug-in just using AI tools? Before we dig in I want to give everyone who is not a coder some encouragement to jump in and try things out. The quick answer is yes! 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...

Using OpenStreetMap (OSM) and JOSM (Java OpenStreetMap Editor) has completely transformed my perspective on places in Ghana. What used to be just names on a map are now vibrant locations I explore, analyze, and contribute to in meaningful ways. With each mapping session, I am a digital explorer, uncovering hidden details about my country. While tracing highways, POIs, buildings, and rivers, to ensure that every corner of Ghana is well represented, I explore!. From the bustling streets of Accra to the serene landscapes of the Volta Region, my virtual travels take me everywhere without even leaving my seat. As I explore and see places, I contribute data to solve real-world problems. Through OSM, I have contributed to flood risk assessments, improved accessibility to schools, and even helped emergency responders find critical locations. It’s amazing to know that my little edits can make a big difference in someone’s life. Mapping is no longer just a hobby; it’s a passion, a...

Die Praxis der Sperren-Festsetzung ist eine Farce! Was an meinem Profil auffallen könnte, ist die Tatsache, dass ich schon mal gesperrt war. Der elektronische Pranger von OSM vergisst das nicht.

Die sprechen allen ansonsten hochgehaltenen Prinzipien wie Fairness, Transparenz, Teilhabe Hohn.

Another one got ignored today, another road left unmapped, another place erased because it wasn’t profitable enough to exist on a corporate map. No one noticed, because no one was supposed to. They don’t talk about the missing footpaths, the streets that don’t appear because they aren’t in a government database, the communities left invisible because they don’t generate ad revenue. They don’t talk about how your map—your view of the world—is decided not by truth, but by business interests. They call us idealists, hobbyists, dreamers. They say the world has already been mapped. But they are wrong. We are the ones who see the gaps. We are the ones who refuse to let our neighborhoods, our histories, our stories be erased. We are the ones who put the world on the map—not for profit, but for people. Yes, I am a mapper. My crime is that of curiosity. My crime is refusing to accept a world where only what is profitable is visible. My crime is knowing that no company, no...

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. SELECT ST_AsText(ST_Difference( 'POLYGON((0 0, 1 0, 1 1, 0 1, 0 0))', 'POLYGON((-1 -1, 3 -1, 3 3, -1 3, -1 -1))' )) If you have a data set and are running...

I’m back home! All the uploads done! Yeah! Street-level imagery As I had written about earlier, I was on tour with actually, to be precise, one of the bands I’m in under the title/ program “The Dubliners Experience” in the Netherlands from Jan 15th to Feb 1st. The GoPro Max was our constant companion on the roof of the tour bus. It covers mostly motorways and the areas around concert venues, of course. I also walked around the campsite we stayed at (band life isn’t as glamorous as they make it out to be in the movies after all) with it, but that imagery is not super useful, I’m afraid. How much can you map in a fen, when there are not even leaves on the trees to map species…But still, the area got covered. I was especially keen to upload to Panoramax, because the coverage was quite poor which does not mean to discredit the people who have already contributed, of course! I’ll give you some before and after screenshots, some of which I had already shared on Mastodon...

Hi OSM folks, Yesterday I finished mapping West Virginia’s forest landcover for OSM in 5 years! It was a big project and definitely the next one will be a bigger one but because of that I’m gonna do it in a pace that I can maintain. If I have to stop, then I stop. Well, it’s just a hobby for me. As I announced on Mapping USA, I’m mapping Pennsylvania from now on. I’m really interested in the history of that state, The Keystone State. And yes, I just wanted to try myself out how I could map forest landcover outside of Europe. It seems everyone seems hyped and I like this! I’m not a robot so I can’t work on it 24/7 due to my personal life and I know i’m not making a 100% accurate landcover, but hey, I learnt some tricks which I’m taking advantage of! Sometimes I also criticise the quality I do but well people usually improve as time flies.

Jak už jsem napsal dříve, tak k mapování mého města jsem se dostal z konkrétních důvodů. Online mapa OSM byla tenkrát nedostatečně zakreslená a mnoho informací bylo zastaralých nebo chybějících. Trápilo mne to. Druhý důvod byl, že jsem se opakovaně setkával s návštěvníky a turisty, kteří něco hledali a na jejich mapě to nemohli najít. Neuměl jsem jim to rychle ukázat. Bylo to pořád dokola. Jiné mapy tu existovaly, ale kromě komerční varianty tištěných map, nebo mapových cedulí místního mapového vydavatele, nenabízely turistům dostatečně přesné informace. A to jsem chtěl zlepšit. Rozhodl jsem se pro OSM. Teď po několika letech by bylo fajn napsat, co se podle mé zkušenosti u uživatelů map změnilo a co ne. Nakonec pár slov, co by se dalo vylepšit. Předně musím říci, že povědomí konkrétně o mapě OSM, je u bloudících turistů velmi slabé, protože znají a používají většinou jiné online mapy. Pokud je vůbec používají. Mají k tomu své důvody.

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. I also recently have ‘become a coder’ again, thanks to the power of AI tools.

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.

Kyle Barron, Cloud Engineer at Development Seed. 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...

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...

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.

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...

Back to entry 1 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. I am still not fully well (for reasons), and I really want to be the person she married, a helpful full partner. It is frustrating to still be taking more than I’m giving.

Back to entry 1 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...

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...

In the past we have wrote about using simulation to build synthetic datasets for trajectory analysis due to the limited availability of real world comprehensive datasets. In relation to this work we  (Andreas Züfle, Dieter Pfoser, Carola Wenk, Hamdi Kavak, Taylor Anderson, Joon-Seok Kim, Nathan Holt, Andrew DiAntonio and myself) have a new vision paper entitled "In Silico Human Mobility Data Science: Leveraging Massive Simulated Mobility Data" published in Transactions on Spatial Algorithms and Systems. In the paper we sketch out a framework  for in silico mobility data science. The rationale being in someway that mobility data alone does not tell us much about why people do what do and to quote from the paper "but imagine a world where we can go back in time to ask people about the purpose of their mobility to understand why an individual visited a place of interest." By building models (aka, agent-based models) we can do just that which therefore allows us to build in silico human...

Taylor Geospatial Engine and the core team of the Field Boundaries for Agriculture (fiboa) project are happy to share another technical update from Matthias Mohr and the Cloud-Native Geospatial Foundation on the continued development of open source tools to accelerate innovation in AI and computer vision models to extract field boundaries from earth observation imagery. The post Creating Interoperable Field Boundary Data with the fiboa Converter Tool | Cloud-Native Geospatial Foundation appeared first on Taylor Geospatial Engine.

The post describes the creation of an ArcGIS Dashboard in ArcGIS Enterprise to track data collection progress on field assets, including photo capturing. A dynamic query counts the number of attached photos and a map displays the results. The feature class is in an Enterprise Geodatabase on SQL Server with enabled attachments and versioning.

Automation is crucial in my work as a Geospatial Professional. I rely on three key types of automation: Dynamic, which reacts to user interaction; Scheduled, which runs tasks at set intervals; and Triggered, which responds to specific events. These methods streamline data management, map creation, and dashboard building for efficient projects.

It’s already been three years since the last release of the STAC specification and it’s time to improve the specification based on feedback from the STAC community that we received since the last release. After some intense time of discussions and document editing, we are proud to announce the release of STAC 1.1.0-beta.1. 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...

In May, we discussed Field Boundaries for Agriculture (fiboa) and the fiboa ecosystem and mentioned that there is a new converter tool, which can take non-fiboa datasets and help you turn it into fiboa datasets. Back then we had 5 very similar datasets converted. In the meantime, we’ve converted additional datasets and improved the converter tool. Today, we’d like to give an update on the status and show how easy it is for you to make your field boundaries more useful by converting and providing them in a “standardized” format. Seven people are currently working on creating more than 40 converters: ~20 converters are fully implemented and easily usable ~20 converters are currently in development and available in a draft version How does it work that we can convert so many datasets so easily? We have implemented the fiboa Command Line Interface (CLI), which is a program that offers various tools to work with field boundary data. One of them is a command to convert...

Over two years ago, the GeoParquet project brought together a diverse group of interests around a clear objective: standardizing how geospatial data is used within Parquet. The initial goal was modest: to ensure that any tool reading or writing spatially located geometries (points, lines and polygons) does so in a consistent and interoperable way. But the ultimate goal of the effort has been to make geospatial a primary data type within the broader data community, thereby breaking the ‘GIS’ data silo and enabling the seamless integration of geospatial data with all other data types. We envision a world where spatial data is simply another column in your dataset, not a special case requiring unique handling. This integration will unlock new insights, reduce the need for specialized tools, and make geospatial information accessible to a broader range of users and innovations. Without standardization, the current situation is that...

Accurate distance and angle measurements on Earth’s surface are the focus of land surveying, both an art and a science.

As Earth observation data becomes more abundant and diverse, the Earth Observation user community has spent considerable effort trying to find a common definition of “Analysis-Ready Data” (ARD). One of the most obvious reasons this is hard is that it relies on the assumption that we can predict what kind of analysis a user wants to perform. Certainly, someone using satellite imagery to analyze evapotranspiration is going to need something very different from someone trying to detect illegal mines. Despite this, we believe there is some degree of preprocessing, metadata provision, and harmonization that will be useful for most users to move more quickly. This blog post is an overview of our current thinking on ARD based on work we’ve been doing with NASA, the Committee on Earth Observation Satellites (CEOS) Systems Engineering Office, and others over the past year. STAC Some of the challenges of aligning around a definition of ARD has been solved by adoption of the...

In the past we have explored various ways to explore vaccine hesitancy and keeping with this theme we have a new paper published in PLOS ONE entitled "Understanding the determinants of vaccine hesitancy in the United States: A comparison of social surveys and social media" with Kuleen Sasse, Ron Mahabir, Olga Gkountouna and Arie Croitoru. In the paper we use social, demographic and economic (e.g., US Census) variables to predict COVID-19 vaccine hesitancy levels in the ten most populous US metropolitan statistical areas (MSAs). By using  machine learning algorithms (e.g., linear regression, random forest regression, and XGBoost regression) we compare a set of baseline models that contain only these variables with models that incorporate survey data and social media (i.e., Twitter) data separately. We find that different algorithms perform differently along with variations in influential variables such as age, ethnicity, occupation, and political inclination across the five hesitancy...

The fifth SatSummit kicks off on Thursday.

Understanding precedes innovative.

Following up on the importance of data schemas and ID’s blog post, I wanted to dig into the topic of data schemas. In the Cloud Native Spatial Data Infrastructure section, it posited that instead of a model like OpenStreetMap, where everyone contributes to a single database, a better inspiration might be open source software. This way of working wouldn’t require everyone to follow the same set of community and governance norms — it would encourage different approaches and more experimentation, and a wider variety of data types to collaborate around. That section closed with the thought: We … don’t envision a single data schema that everyone has to align to. Instead, there’s a way to start with a small, common core of information that gives data providers the flexibility to use the pieces that are relevant to them and easily add their own. I believe the foundation we’ve been laying with Cloud Native Geospatial formats has the potential to lead to much greater...

In past blog posts we have discussed how one can use social media to study vaccine discussions and even tried to build a very simple disease model where vaccination rates were a factor in the spread of an outbreak. However, when it comes to vaccinations, especially that of Covid-19 vaccine there has been intense discussions in the physical (e.g., family), hybrid (e.g., work, school) and cyber (e.g., social media) spaces we inhabit. One thing that is unclear is how do these discussions in these various hybrid spaces impact our decision to get vaccinated or not? To this end, in a new paper published in the International Journal of Geographical Information Science with Fuzhen Yin, Li Yin and myself, entitled “How information propagation in hybrid spaces affects decision-making: using ABM to simulate Covid-19 vaccine uptake” we explore this. More specially we explore how through opinion dynamics modeling, how agents can chose to vaccinate or not and how much emphasis they place on...

Back to entry 1 Scanxiety. This is where I am right now. Scanxiety. Each stage of the cancer experience is marked by a particular set of tests, of scans. I actually managed to get through my first set of scans surprisingly calmly. After getting diagnosed (“there’s some cancer in you”), they send you for “staging”, which is an MRI and CT scan. These scans both involve large, Star Trek seeming machines, which make amazing noises, and in the case of the CT machine I was put through was decorated with colorful LED lights by the manufacturer (because it didn’t look whizzy enough to start with?). I kind of internalized the initial “broad-brush” staging my GI gave me, which was that it was a tumor caught early so I would be early stage, so I didn’t worry. And it turned out, that was a good thing, since the scans didn’t contradict that story, and I didn’t worry. The CT scan, though, did turn up a spot on my hip bone. “Oh, that might be a bone cancer, but it’s probably not.” Might be...

When we speak about the geospatial industry, there’s much discussion on how many different areas of study can intersect with it.

Back to entry 1 I have a profoundly embarassing cancer. Say it with me “rectal cancer”. “Rectal cancer”. Why is it embarassing? Poop!?! Maybe we are all still six, somewhere deep inside. When Ryan Reynolds got a colonoscopy on camera, to raise awareness of colorectal cancer screening, part of the frisson of the whole thing was that yes, somehow having this procedure done is really embarassing. So, watch the video, it’s really nothing but an ordinary medical procedure that could very well save your life. And Ryan Reynolds is charming. Meanwhile, colo-rectal cancers remain tough to talk about, because frankly the colonoscopy is the least of it. Not having control of your bowels is, well, really embarassing in our culture.

When we can talk about our feelings, they become less overwhelming, less upsetting, and less scary. The people we trust with that important talk can help us know that we are not alone.”– Fred Rogers When I found out I had rectal cancer, I hit the internet hard and immediately found the ColonTown community of communities. It has turned out to be simultaneously the most reassuring and the most anxiety producing place on the internet for me. On the reassuring side, even though colorectal cancer is third most prevalent cancer world-wide, it is not widely talked about, so the community was reassuring: there are other people out there going through this; many are already through it. There are also a lot of aspects of the rectal cancer treatment process that the medical system seems ill-equiped to support. I was sent home from major surgery with very little guidance in hand...

The hidden element that underpins everything.

fiboa is a new collaborative project to improve farm field boundary data interoperability and other associated agriculture data, that we introduced a couple of weeks ago. This post complements our previous deep dive into the follow-up post core specification and its extensions. In that post, we mentioned that fiboa is not just a specification; it’s a complete system. It includes the entire ecosystem of data adhering to the specification, the discussions and conversations that evolve the specs, and of course, the community people who are building it all together. In this post, we introduce the initial tools, data, and community that form that ecosystem. Data The goal of fiboa isn’t to create a data schema - the schema is a means to get at the goal of more data and more open data about field boundaries and agriculture to help us make better decisions. And indeed the best way to make a good data schema is not to go in a room and try to create the most perfect ontology -...

Back to entry 1 I’m still here. There’s nothing like spending some time in hospital to get a visceral reminder that “well, things could be a whole lot worse”. There are plenty of people dealing with far more dire scenarios than a little surgical recovery with a discharge in a handful of days. My stay was scheduled for 3-5 days, and I was discharged in 4, a testament to my good health going in and the skill of my surgeon in doing the least harm while still doing what needed to be done. It was still a long and eye-opening four days. Psychologically, the worst time was the 24 hours before they put me under. Fasting, and hard antibiotics, and bowel prep, and anticipation, and an early start. I shed some tears in the pre-op while waiting to roll into the OR, for sure. The four days of recovery in hospital included all sorts of new indignities, from catheterization to shitting the bed, from adult diapers to the generalized humiliation of being unable to move, pinned down by gravity...

Which direction will it take? My insights from a industry disruptering conference in the Canadian Rockies.

At the recent American Association of Geographers (AAG) Annual Meeting in Honolulu, Hawaii, our group had several presentations showcasing some of the research we are doing here at the University at Buffalo with respect to agent-based modeling, social media analysis and machine learning. If these sound of interest feel free to reach out to us to find out more. First up was Na (Richard) Jiang who presented a paper entitled "Populating Digital Twins with Humans: A Framework Utilizing Artificial Agents". In this presentation he showcase our workflow of embedding agents in models of cities using examples from simple commuting models (like that shown below) to the spread of diseases.AbstractOver the last few decades, considerable efforts have been placed in creating digital virtual worlds. Ranging in applications from engineering, geography, industry, and translation. More recently, with the growth of computational resources and the explosion of spatial data sources (e.g., satellite...

Last week, we introduced fiboa, a collaborative project with the Taylor Geospatial Engine (TGE) designed to standardize farm field boundary data and bootstrap an ‘architecture of participation’ around agricultural and related data. The center of fiboa is a specification for representing field boundary data in GeoJSON & GeoParquet in a standard way, with optional ‘extensions’ that specify additional attributes. But we believe that thinking of fiboa as ‘just’ a specification is outdated. fiboa is the entire ecosystem of data adhering to the specification, tools to help convert data (including using AI models to in turn create more data), the discussions and conversations that evolve the specs, and of course the community people who are building it all together. This blog post dives into the heart of fiboa: the core specification and its extensions. We’ll explore the core attributes that define this format and how the extensions enable interoperability of all types of...

It occurs to me that I have been Blendering for a long time.

Members gathered in Ghent, Belgium to talk about the future of open map data.

Geography is the study of the world around us, including people, the places they live and the environment. On the Geographical Association‘s website they state that geography as a subject “speaks directly to young people’s curiosity, wonder and concern for the world”. There are many ways in which we can ignite this curiosity and wonderContinue reading "Using a Range of Texts in the Geography Classroom"

We are excited to announce fiboa (Field Boundaries for Agriculture), a new project we’re collaborating on with the Taylor Geospatial Engine (TGE) focused on improving interoperability of farm field boundary data and other associated agriculture data. We’re excited about the enormous potential of this project, and we’ve already started a community of people who share our excitement. fiboa is the first concrete result from the TGE Field Boundary Initiative, which aims to enable practical applications of AI and computer vision to Earth observation imagery for a better understanding of global food security. The initiative has spurred collaboration between academia, industry, NGOs, and governmental organizations toward creating shared global field boundary datasets that can be used to create a more sustainable and equitable agriculture sector. We worked with TGE to launch this effort in February at a workshop in St. Louis that brought together almost 20 different...

Light Detention and Ranging (Lidar) is a detention system that uses lasers to examine the earth’s surface. It uses airborne tools to examine to collect spatial information.

Account Manager: Thanks everyone, for making time for this call.

In the past we have blogged about the challenges of agent-based modeling but one thing we have not written much about is the challenge of uncertainty especailly when it comes to model calibration. This uncertainty is a challenge when it when it comes to situations where various parameter sets fit observed data equally well. This is known as equifinality which is a principle or phenomenon in system theory that implies that different paths can lead to the same final state or outcome. In a new paper with paper with Moongi Choi, Neng Wan, Simon Brewer, Thomas Cova and Alexander Hohl entitled "Addressing Equifinality in Agent-based Modeling: A Sequential Parameter Space Search Method Based on Sensitivity Analysis" we explore this issue. More specifically we introduce an Sequential Parameter Space Search (SPS) algorithm to confront the equifinality challenge in calibrating fine-scale agent-based simulations with coarse-scale observed geospatial data, ensuring accurate model selection using...

The evolution of geospatial technology from paper maps to GIS programs is a testament to the power of human ingenuity and the relentless pursuit of progress.

Finding inevitability.

Over two days, city leaders from around the globe designed GEO’s new Urban Heat data services.

We created the Cloud-Native Geospatial Foundation because we’ve noticed rapid adoption of cloud-native geospatial formats, such as Cloud-Optimized GeoTIFF (COG), SpatioTemporal Asset Catalogs (STAC), Zarr, and GeoParquet. Both data providers and users enjoy time and cost savings when using cloud-native formats, and we believe there’s a need to help more people learn how to benefit from them. Despite that, creating more cloud-native formats is a non-goal for us. There are plenty of people within our community working on cloud-native formats such as Cloud-Optimized Point Clouds (COPC), GeoZarr, and PMTiles. At this point, most use cases are covered by existing formats.1 In addition to the time and cost savings, one huge benefit of using cloud-native data formats is interoperability – the ability for different systems to share information easily. Common data formats are an essential part of interoperability, but we’re starting to explore a new dimension of data that is...

High performance geospatial with GeoArrow and GeoParquet

On Monday, we had our regular GeoParquet community meeting, and everyone agreed it’s a pretty exciting time, but that we need to tell people more about what we’re up to. We’re feeling ‘feature complete’ for a version 1.1 release of the specification, and so wanted to give all implementors a heads up so they could try it out and give any last feedback. And to also just share what’s been cooking. We’ll have a full announcement release when the 1.1 release goes out, so consider this a bit of a preview. The focus for version 1.1 has been on ‘spatial optimizations’. We actually decided to not include any spatial index or hints in GeoParquet 1.0. Which may seem surprising, but we really wanted to focus on interoperability – making sure that everyone writing geospatial data into Parquet would write it the same way. We knew that there was a whole lot that could be done to make it a better spatial format, but we wanted to give more time for experimentation with different...

Quantifying community resilience especially after a disaster is an open research challenge. However, with the growth in mobility datasets such as SafeGraph we are being given new opportunities to study how communities rebound from disaster.  To this end, in a new paper with Qingqing Chen and Boyu Wang entitled "Community resilience to wildfires: A network analysis approach by utilizing human mobility data" which was published in Computers, Environment and Urban Systems we develop a framework to quantify resilience after a disaster using network analysis. To showcase this framework we us a human mobility data associated with two wildfires (Mendocino Complex and Camp wildfires) in California and measure the robustness and vulnerability of different communities over time. Our results show community resilience is closely tied to socio-economic and built environmental traits of the affected areas and as such our approach paves a way to study disasters and their long-term impacts on...

 My thanks to Mark Brooks for this advice and tips. 

Dr. Qiusheng Wu, Associate Professor at the University of Tennessee. You are behind two game-changing tools: leafmap, a user-friendly Python library for interactive mapping and geospatial exploration, and geemap, a Python package for seamlessly integrating Earth Engine data analysis and visualization. What motivates you to invest your time and expertise in creating free, open-source tools? My primary motivation stems from a passion for harnessing the power of geospatial technologies to address environmental challenges. In the Spring of 2020, while teaching Earth Engine at the University of Tennessee, I encountered a significant obstacle. The Earth Engine Python API documentation was very limited, making it difficult for my students to effectively visualize and explore Earth Engine data interactively. This challenge inspired me to create geemap to bridge this gap. Since its initial release on GitHub in March 2020, I...

Over the last year or so there has been a lot of hype about artificial intelligence (AI) and Large Language Models (LLMs) in particular, such as Generative Pre-trained Transformers (GPT) like ChatGPT. In a recent editorial in Environment and Planning B written by Qingqing Chen and myself we discussed how LLMs could be used for lower the barrier for researchers wishing to study urban problems through the lens of urban analytics. For example, analyzing street view images in the past required training and segmentation of such data which a time consuming and a rather technical task. But what can be done using ChatGPT? To test this we provided ChatGPT some images from Flickr and Mapillary: Examples of using ChatGPT for extracting information from imagery.And then asked it some questions and we were quite amazed by the answers:  Examples questions and responses when using ChatGPT for extracting information from imagery.If this sounds of interest I encourage you to read the editorial and...
