In the world of geospatial technology, two powerful currents shape our digital maps: the polished, enterprise-ready ecosystems of proprietary software like Esri's ArcGIS and the passionate, community-driven innovation of Free and Open Source Software (FOSS). This is not a story of opposition, but of a complex, thriving balance. From corporate giants optimizing global logistics to volunteer armies mapping disaster zones in real-time to save lives, both models are fundamental to our modern world.   This article delves into the heart of this dynamic, exploring the philosophies that divide and the open standards that unite these two worlds. We deconstruct the powerful FOSS4G stack—featuring titans like QGIS and PostGIS—and examine the sustainable business models that prove "free" software is a viable, enterprise-grade choice.   More than just code, we uncover the soul of the movement: the Open Source Geospatial Foundation (OSGeo) and the global community that...

Last week someone posted an animation of a Typographic Map of France on Reddit.

by Minh NguyễnCore Software Development Facilitator, OpenStreetMap Foundation In June, I had the privilege of representing OpenStreetMap as part of the Sovereign Tech Agency’s delegation at UN Open Source Week in New York City. Joining me was Sarah Hoffmann, who maintains several well-known OSM software projects. This was a unique opportunity to raise OSM’s profile among global institutional supporters of open source projects and promote best practices for fostering and sustaining authentic open source communities. Among the open source projects represented at the event, OSM stands out as an open data project, giving us a special perspective on issues of governance and community-building. At the unconference-style “Maintain-A-Thon”, Sarah shared some of her deep experience as maintainer of Nominatim in discussing how to create accessible entry points for new contributors.

Mapping Munchies Tuesday, September 2nd 2025, 12:50 BST London, UK My wife and I run a blog where we review the restaurants we go to when we go out for dinner on Friday evenings. And on this website you can look at all the reviews, but it is a bit difficult to see as to where the restaurants are. So I decided that I wanted to add a map to our website. We have already recorded the addresses for this, but not quite yet the coordinates. So in order to show a map we needed to convert the addresses to coordinates, and there are several ways of doing so. You can roll something yourself with a Nominatim, which is part of the OpenStreetMap project. But I decided to try a different service, called OpenCageData, which provides a geocoding service. I didn't want to maintain a geocoder myself. After signing up and creating API keys, I used their PHP library (handily...

In 2025 alone I found vandalism incidents specifically targeting map of Indonesian parliament compound twice, in March and now in late August. Thankfully these are all restored. What made me sad that some Indonesians don’t understand the OpenStreetMap at all, what they only know in their head is political activism. They do by erasing - or editing - the place of institution they despise. Not really sure if these incidents are unique to maps in Indonesia or there’s international example of politically motivated vandalism of OSM maps?

Memang repot menghadapi sebagian netizen Indonesia yang sepertinya menyalahgunakan peta sebagai alat perjuangan politik ketimbang bantuan navigasi dan informasi. Selama delapan bulan terakhir, vandalisme bernuansa politik sudah dua kali terjadi: Maret 2025, dengan mengubah batas wilayah negara (yang mungkin gampang diketahui oleh pengurus OSM); dan Agustus 2025 dengan mengganti dua tempat menjadi reservoir. Target utamanya kalau tidak lain dan tidak bukan kompleks DPR/MPR, khusus untuk Agustus 2025 juga menimpa peta kawasan Polda Metro Jaya (DKI Jakarta). Jika anda punya ketidakpuasan politik di Indonesia, jelas OpenStreetMap bukan tempatnya dan yang anda hadapi adalah dihukum oleh pengurus OpenStreetMap. Mungkin ini satu-satunya vandalisme bernuansa politik di OpenStreetMap. Jika anda berpolitik, cobalah untuk menulis di media sosial dan jangan bikin repot orang lain.

Styles for vector tiles are typically written in the MapLibre GL style language. These definitions exist in JSON, which, for various reasons, is not a good language for humans to write in. Software called Charites preprocessed my Street Spirit style to improve readability. This helped a great deal and removed the two largest pain points: no comments and only one file. Charites’ main features are:1 letting you write in YAML instead of JSON, importing other YAML files into the main one, and the use of simple variables to allow common style constants to be set once. I made use of the first two features, but I still found myself limited by them. I still faced issues where the project’s structure revolved around the styling language rather than what makes sense to a cartographer. A good example of this was road layers. With Charites I had to have separate files for each layer, so I had separate files for each of the thirteen layers. With glug I was able to have one file...

Introduction This report reflects on my journey during Google Summer of Code 2025, where I worked on the 3D Model Repository (3DMR): a platform that makes high-quality, CC-licensed 3D assets discoverable, reusable, and directly linkable to OpenStreetMap (OSM) features. At its core, 3DMR is about more than just hosting models: it’s about ensuring provenance, metadata quality, and renderer-friendly optimized delivery. Initial Project Goals Details of my original proposal can be found here: OSM: Modernize the 3D Model Repository. In essence, the goal of the project under GSoC 2025 was to revive the 3DMR project by upgrading Django and related dependencies and standardizing on the widely accepted glTF/GLB format so renderers can load models predictably. Work Done My detailed progress notes are documented on the community thread. A high level summary of the major milestones can be highlighted as: Infrastructure modernization: Upgraded Django (to 5.2.2), resolved numerous...

Lite funderingar, såhär på en onsdag kväll… Jag använder mig av Organic Maps när jag ska navigera och upptäcker ofta att de adresser jag ska til, inte finns med i kartan. Varför jag ofta får leta upp kordinaterna först, på t.ex Eniro, för säkra mig att jag hittar rätt. I samband med det har jag en del funderingar: Om jag lägger till en adress i kartan, måste någon annan då först bekräfta att den finns, innan ändringen träder i kraft? Om så är fallet, hur går det till? Kollar Hen det rent fysiskt, på plats alltså, eller kan man göra det via andra kart-tjänster (typ Enir*, Gurgel m.fl)? Ibland hittar jag frågor i OSM, rörande områden som jag ofta befinner mig i. Är det då ok att jag kollar/ger svar, på det som frågas om (förutsatt att jag vet)? Och räcker det för att en ändring i kartan kan ske, och att ärendet därmed kan avslutas? Kan jag avsluta ett ärende på eget bevåg? I telefonen hittar jag ingen kategori för just Ladugård. Jag kör, och jobbar, mest ute på landet, vilket...

OSM exists now since more than 20 years. During this time, a tagging scheme evolved. It has undergone several changes since, is partly approved by the community, but never anything was forced. The freedom to invent new tags is considered a strength of OSM. The OSM tagging scheme is clearly a result of swarm intelligence, which is sometimes said to be superior. I wondered how well this worked and thus started to analyse it. I’ll probably blog about this in a loose series of blog posts, starting today with looking at the highway tag, which according to the wiki identifies “any kind of road, street or path.” In most cases, OSM elements are categorised in a hierarchical manner, with every step narrowing the meaning of the former step: highway=service, service=driveway, driveway=garage for example. A top level type=highway is missing and has to be derived implicitly.1 The values of a certain tag should ideally be choosen in a way, that there is a match for every object in the real...

High on a remote mountaintop, you spot a metallic glint set in the bedrock: a weathered brass disk stamped with cryptic words and a perfect triangle. What is this object? It's a geodetic survey marker, a physical anchor from a two-century-long scientific odyssey to measure and map a continent. This is the story of how a network of brass and sweat, laid down with grueling labor and uncompromising precision, formed the invisible framework of our modern world. Discover the audacious vision of Ferdinand Hassler, the brutal life of a survey party, and the elegant science of triangulation that transformed an unmapped frontier into a tangible nation. But in an age of GPS, are these markers mere relics? Explore the paradox of why these "silent sentinels" are more critical than ever, anchoring our virtual, satellite-driven age to the solid ground beneath our feet.

I once walked past a small building, spotted that it’s got an address, and added it to OSM. Then I walked past it again, the building had its facade updated–and the address was nowhere to be seen. We map a lot of ‘virtual’ objects in OpenStreetMap, boundaries and routes, but even addresses, the holy grail of survey, often end up virtual. Take osm.org/way/1173366729: there isn’t an address on the building’s facade, yet 2GIS and Yandex.Maps have one. Is there a private data agreement between the government and map services? 2GIS had some kind of city district polygons (elections related?) that someone even gave a review to asking what they were, and the Ministry of Information and/or of Digital Development already love giving out personal data of citizens to random software companies and banks in the name of ‘digitization’ (my bank’s app has everyone’s status with the police inspectorate and the psychoneurological dispensary and boldly let you see your own!), so it’s very...

I have noticed that the Apple mapping team, in their work within Kazakhstan, consistently mismapped various highway=* ways, for example: Mistagging of courtyard highways from highway=service to highway=residential.[2] Retagging of a highway=footway to a highway=residential, seemingly without any on-the-ground knowledge.[3][4] Various other bizarre additions or edits to service highways (also often mistagged), that I sometimes corrected or rolled back.[5] If the Apple team does not have familiarity with how the highway tags are applied in a country[6] (a country here with a small OpenStreetMap community at that), or the specifics of urban development that span half the continent, then they, simply, should not map, and definitely not make the state of the map ever so slightly worse.

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. La entrada When your field mapping workflows break your maps se publicó primero en Fulcrum.

Spatialty emphasizes a modern GIS approach centered on automation, accessibility, and education, transforming challenges into opportunities and enhancing organizational decision-making through geospatial intelligence.

Over the last few weeks we have updated and overhauled the “Contributing” section on the osm2pgsql website. We want to make it easier for users and contributors to understand what our plans are for osm2pgsql, what are the open issues and what you can do to help. The new Contributing Overview no longer focuses on coding because there are so many more ways to help the project than with code. Whether you are a user, have ideas on improving the documentation, or want to show your use case, everything helps to make osm2pgsql better. We have also updated the road map with the most important milestones for getting to the next major release 3. If you are looking at a concrete project to work on, have a look at the updated project ideas.

Latitude and Longitude: The Foundation of Map Reading Maps are far more than static illustrations; they are powerful tools that help people navigate, explore, and understand the world. One of the most essential elements on any map is the system of latitude and longitude, an invisible grid that enables anyone to pinpoint any location on Earth with precision. Latitude lines run horizontally across the globe and measure how far north or south a place is from the Equator, which is set at 0°. These lines, often called parallels, remain equal distances apart as they circle the Earth, dividing it into the Northern and Southern Hemispheres. The range begins at 0° at the Equator and extends to 90° north at the North Pole and 90° south at the South Pole. This system allows us to describe a location’s exact position on the north-south axis of the Earth, providing an essential framework for global navigation and geographic understanding. Without latitude, it would be impossible to...

tl;dr: slightly less than an hour. This was prompted initially by a forum comment (I can’t actually remember exactly where or by whom) that creating maps based on OSM was for “developers” and not “normal people” (not in those exact words), and by the thread here.

New code will probably have some errors, the compiler finds some of them and refuses to produce the final program. So far so good. But code also contains lots of issues that are not outright errors, they just look “suspicious” to the compiler in one way or another. Some of them turn out to be actual errors, but sometimes the code is totally okay in the specific context. The compiler can’t tell for sure, so it emits a warning and keeps going. Different compilers and different versions of those compilers print different warnings. And then there are things that are not problems by themselves, they just make the code harder to read, possibly leading to more problems down the line. Or sometimes a tool can detect that you are using an “old-fashioned” way of doing things and there is a better, more modern or more efficient way, to achieve the same thing. Some of these issues are also detected by the compiler, but for most programming languages there are extra tools, so called...

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

NIQ’s Oliver Pape explains how NIQ’s strategic partnership with Mapidea transforms market and consumer data into powerful, actionable insights. By uniting NIQ’s datasets with Mapidea’s geospatial intelligence platform, clients gain faster, clearer decision-making capabilities—unlocking new opportunities for growth and competitive advantage.

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

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

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...

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...

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).

With Miles Kauffman

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.

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...

A stark vision for America's fiscal future now casts an ominous shadow, as the proposed Fiscal Year 2026 budget threatens a veritable demolition of non-defense federal capabilities, launching an unprecedented assault on the agencies underpinning our nation's world-leading geospatial infrastructure with a staggering $163 billion targeted for removal from base non-defense 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 to backfill widening data gaps and maintain "GEOINT Supremacy" with a critically weakened foundational support system.

The high cost of commercial remote sensing data is a major obstacle to widespread adoption.

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.

As the AAG has just wrapped up I thought I would write brief (well actually quite long) post on the talks that I was involved with at the conference. These talks would not have been possible without the many great students and colleagues who I have been collaborating with over time. Below you will find a brief summary of the talks and if any sound interesting, please reach out and we can give you more details. 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.

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.

Back to entry 1 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...

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

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.

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.

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...

Are the Geoawesome Top 100 Companies worth buying?

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. I’ll dive into more of the experience in my next post, but it meant...

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. If this sounds of interest, below you can read the abstract to the paper, see some of the figures we use to build our argument, while at the bottom of the post you can see the full reference and a link to the actual paper.Abstract: As more satellite imagery has become openly...

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.

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...

Can you tell us a bit about your background and what initially drew you to this area? I have a bit of a nontraditional background; I have virtually no official training in geography or computer science.

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

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.

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...

Innovation, at its best, is invisible; there is just an audible sigh of satisfaction. A good strategy is to make things look the same but be better.

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

Building upon last year’s successful sessions related to geosimulation, were various topics and issues from across the urban, social and environmental fields and the resulting application areas. More excitingly, we are witnessing the emergence of the integration of cutting-edge techniques (e.g., machine learning and generative AI) which is energizing the geosimulation community as they offer new approaches for advancing geosimulations. This year, the 2025 AAG Annual Meeting will take place in Detroit, Michigan from March 24 to March 28. We are continuing to organize sessions on "Geosimulations for Addressing Societal Challenges," and we encourage you to submit abstracts if this area aligns with your research interests.Session Description: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...

A quick post today to talk about a couple of PostGIS functions I learnt recently. I had a CSV file that contained well-known binary (WKB) representations of geometries, stored as hexadecimal strings. I imported the CSV into a PostGIS database, and wanted to convert these to be proper PostGIS geometries. I initially went for the […]

At TGE, our guiding principle is to contribute purposefully by elevating research-grade innovation into user-friendly and accessible capabilities that have broad awareness and reach. Because we are a very small team, this means that we are heads down most of the time. It’s important this week to take a minute to pop up and do a little celebrating! Two very different efforts, that are both critically important to us, have reached milestones. The post Celebrating Our Community’s Success appeared first on Taylor Geospatial Engine.

🔍 Insights and deep dives for Geospatial AI

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. From writing about my experience here, I have heard from other cancer survivors, and other folks who have...

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...

Don't Get Blinded By Your Vendor's Stories

Last week I had the honor to give a keynote talk entitled "Exploring the World from the Bottom Up with GIS and Agent-based Models: Past, Present and Future" at the 19th annual Social Simulation Conference which is the European Social Simulation Association (ESSA) annual conference. Attending the conference was a great experience being exposed to various applications of social simulation, catching up with old friends and meeting many new people. For anyone interested below I have pasted the abstract from my talk and the slides from the talk can be found here. Abstract We have seen explosion in the availability of data along with utilizing such data in agent-based models. At the same time, we have seen a huge growth in computational power and the associating agent-based models to real world locations through the use of geographical information systems (GIS). This talk will explore how geographically explicit agent-based models have grown and evolved over the last 20 years taking...

The first significant release of Python bindings for stac-rs.

We’re excited to announce the Cloud-Native Geospatial Forum (CNG) membership program. We have changed our name, but not our commitment to making geospatial data easier to access and use. As geospatial data becomes more important, so does the need for a vendor-agnostic, trusted platform to help people understand the true benefits and limitations of geospatial technology. CNG is stepping up to meet this need, providing a neutral forum where geospatial data users can come together and exchange ideas, share experiences, and learn from one another. Our membership program is designed to unite and empower a diverse community of geospatial professionals from across industries and specialties. In the last few years, we’ve witnessed how the cloud ecosystem, fueled by open standards, has changed how we work with geospatial data online. Cloud-native technologies have created capabilities that have been rapidly adopted across the commercial and public sectors. Despite this, many...

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