Immer wieder wird im Geschäftskontext über Datenqualität gesprochen. Aktuell wird Datenqualität in Diskussionen häufig mit anderen Themen verwoben: Autorität im Sinn von «authoritativeness», Offizialität, Entstehungskontext, Governance-Modelle, Rechtssicherheit, «foi publique» etc. Das sind wichtige weitere Themen rund um Daten. Und diese können im Einzelnen die Erkenntnistiefe erhöhen, aber es lohnt sich meines Erachtens, zuerst die Begrifflichkeiten …

How complete are addresses in OpenStreetMap in Belgium? After several status these previous years (see September 2022, in May 2023, and in May 2024, November 24), I finally adapt the process to analyse addresses completeness for all Belgium!
The aim of this small article is to assess the completeness of addresses in Belgium for OSM, compared to official data. Basically we count the address points in OSM and in official data by municipalities. We don’t check the address quality here, we know there can be errors in OSM data, and even in official data.
How I proceeded
Using QGIS, I gathered OSM addresses and official ones. OSM data is imported in a PostgreSQL database using osm2pgsql based on a pbf file for Belgium from the 24th of April. Official data is coming from BEST address csv files, that gathers Belgian addresses for the 3 regions of the country.
Addresses in OSM can be mapped on buildings (most of the cases), hence on a way, or on a node. I consider only objects with...

The OpenStreetMap Foundation Board has selected Minh Nguyễn as the Core Software Development Facilitator. Here’s Minh to introduce himself, some of his ideas and directions, and opportunities to connect. Welcome, Minh!
Hi, I’m Minh Nguyễn, an OSM contributor and community organizer from California. The OSMF has entrusted me with one of the positions funded through the recently announced Sovereign Tech Fund (STF) investment to facilitate the further long-term development of OSM’s software infrastructure. I’m grateful for the opportunity to serve the OSM community in this way.
For those who don’t know me, I started volunteering for OSM way back in 2008, cleaning up errors in my hometown, Loveland, to cure a bout of homesickness. Then I got extremely carried away, adding little details here and there all over the Midwestern U.S., nurturing a little community of mappers in Silicon Valley, translating OSM into Vietnamese, and serving on the board of OpenStreetMap U.S. In...

Le 14 décembre 2024, Mayotte était frappée par le cyclone Chido, le plus violent qu’elle ait connu depuis plus de 50 ans. Rapidement, l’IGN a diffusé des imageries Pléiades prises les 17, 18, 20, 21 et 24 décembre et a confirmé le 25 décembre que la communauté OSM pouvaient les utiliser comme source dans ses éditions. De suite, j’ai eu l’envie de les utiliser pour évaluer les dommages du bâti. Pourquoi le bâti ? Du point de vue cartographique, parce que les dommages sont plus visibles sur des infrastructures polygonales que ponctuelles ou linéaires. Du point de vue de la réponse de crise, parce que les dégâts étaient particulièrement importants, ayant fait disparaître ou rendu impraticables les foyers de beaucoup d’habitants.

“For those living in the Jabotabek area, how about we hold our first offline monthly talk next time and align it with the TomTom Mapping Party event?”
Initial discussions about hosting an offline gathering began among members in the Greater Jakarta area. A suggestion was made to align the monthly community meeting (usually held online, but in this proposal, it will be held offline for the first time) with an upcoming Mapping Party event organized by TomTom. The idea was presented in an open-ended way, inviting members to consider the possibility when time allowed.

I have added a pin for my house, which is at 38150 N Vista Dr in Livonia! From here, I have encountered tons of wildlife, including fish, and generally been treated pretty well. There are parks nearby, riparian zones, old-growth forests, modern civilization including a hotel with swimming pool, and plenty of transportation opportunities. You can even walk here. There’s water, a lawn, and interesting people here. My basement is the coolest!

This blog post is part of a series of blog posts about the new OSM file format “OMA”. This is the last post. At the end of the article you’ll find links to the other blog entries.
I will end this series of blog posts about the OMA file format with a short summary of all the feedback I have received and a brief outlook. But first I’d like to give you a real-life example that uses OMA files.
A Real-Life Example
Over a year ago I wrote a renderer suitable for displaying micromapped areas. I used it to generate tiles at zoom level 20 for the restricted area of my micromapping project.
Now I have adapted this program to use OMA files and recomputed the tiles for the area of my micromapping project. The program can be found on GitHub; and there’s a slippy map showing the tiles.
For example, this is what the station forecourt of Hilden looks like:

Hello, I have completed work for the first part of the project. Central Wilson and the length of Fish Creek road have reached a point where roads, driveways, structures, and water features have been thoroughly digitized. Check it out and let me know what you think! :)
I am sure there are some things I’ve overlooked and maybe some mistakes in these areas. However, given that they are seeing a fair amount of development, I will likely be returning to them soon to update and double check for possible mistakes.
I do have a question for you all out there, more experienced than me. I have come to despise the existing residential-landuse areas in Wilson. They are a mess and seem to be quite outdated. I would be more than willing to fix or make new ones, but I don’t know if there is a specific way to go about that kind of thing. Do they need to be based on any administrative boundaries or are they a more arbitrary area?
As for what’s next in the project, I am moving east to the Stilson...

Field teams can’t move fast if their inspections live on paper — and too many still do. Crews clip forms to their dashboards, carry pens in their pockets, and return to the office with stacks of paperwork. Some teams have moved past paper, but only slightly: keying inspection notes into spreadsheets back at their desks or trying to document field conditions on phones using disconnected digital field inspection apps.

The relationship between municipalities and populated places in the United States is often not obvious, especially in New England due to the naming of their local governments. Naming them towns has blurred the distinction of populated places and municipal governments, when in reality, a clear distinction can be made between the two.
First, let’s look at the things almost everyone should agree with. Nodes tagged with a “place” tag can be referred to as “populated places”, or named concentrations of people. The GNIS definition of a populated place says it best: “Place or area with clustered or scattered buildings and a permanent human population (city, settlement, town, village). A populated place is usually not incorporated and by definition has no legal boundaries. However, a populated place may [correspond with a] “civil” [entity], the legal boundaries of which may or may not coincide with the perceived populated place. Distinct from Census [places] and Civil [entities].” In...

Readers might of noticed that recently we have been exploring the use of street view images to explore cities or how we can utilize geosocial media to understand the form of function of cities, but one thing we have not explored is the role of smell and how it shapes peoples perceptions of urban spaces. However, in a new paper recently published in the Annals of the American Association of Geographers with Qingqing Chen, Ate Poorthuis we do just that. The paper is entitled "Mapping the Invisible: Decoding Perceived Urban Smells Through Geosocial Media in New York City" In the paper we use text mining techniques to tease out smell related information from over 56 million geolocated tweets which are then assigned to specific small categories (e.g., nature, food, waste) resulting in a new smellscape map for New York city. If this sounds of interest, below you can read the abstract to our paper, see our workflow and resulting smellscape map. While the the analysis steps, along with the...

It’s difficult to write in all map style languages. A style written in JSON, like MapLibre, has a few extra pain points because JSON is not designed for editing by humans.
Some “common” style languages are
CartoCSS
Mapnik XML
MapCSS
MapServer
MapLibre GL/Mapbox GL
Some, like CartoCSS, are designed for human editing, while others, like Mapnik XML, serve as a lower-level language. MapLibre GL falls into this category of not being designed for editing by humans. MapLibre GL preprocessors like glug were designed to help with this, but none of them have taken off. Other style projects like openstreetmap-americana have taken a different route. Their developers have written a program in JavaScript that generates the style.
I’m taking a different route. I’m creating a language that uses minimal pre-processing of its input to produce MapLibre GL. I don’t aim to solve every difficulty with MapLibre GL, only the ones that impact me the most. The end result will be a...

This blog post explains how I handle a typical bug report for the new OSMF Shortbread tiles. Here, I focus on the “island” seems to be missing from “place_labels” report from SomeoneElse
After verifying that the report is correct, I set up my editor environment. It’s useful to have an environment that syntax highlights Jinja SQL files, as well as other files. I use a Visual Studio Code-based editor with the Better Jinja plugin.
The issue is in the place_labels layer. After checking Shortbread, I see that place=island should show at zoom 10 or higher, so there is a bug. Tilekiln creates tiles by reading definitions from shortbread.yaml, so I check there for the place_labels definition.
place_labels:
description: Holds label points for populated places.
fields:
kind: Value of OSM place tag
name: *name
name_en: *name_en

Production inspections are the front line of quality control in manufacturing. But for many teams, they’re also one of the biggest bottlenecks. Manual inspections slow production, vary from one shift to the next, and make it harder to spot patterns across the line. Errors are easy to miss. Data is hard to trust. And as production scales, so do the risks. AI in manufacturing is gaining traction as a way to improve production inspection workflows with greater speed, consistency, and accuracy.

Once I had a concept to render gabled roofs in 3D with OSMgo.org but it did not work. Often the roof looked like broken down. After a long time of abandoning OSMgo, I found a “working” solution and used it in my code. But no, the browser got stuck in an infinite loop %-(
May be update the version of ThreeJS, after years? That took me many many hours. For the geeks: Using es6 needed much export and import. After hours of typing, I fond at last VS-Code plugin to show me the missing variables. Not using “with” any more needed a lot of “this”. Worse, ThreeJS dropped the geometry.merge() and changed the geometry attributes, typing, typing.
Hey, something positive!: Because now Vertex-Colours are used, only one Draw-Call per 3D-tile is needed. OSMgo should run faster now.
With the new ThreeJS the infinite loop was gone, but: the roof was at the wrong place and direction. Some adaptions of the theft code were needed. Now, the City of London looked much better than before. Oh wait, all...

This blog post is part of a series of blog posts about the new OSM file format “OMA”. This is the seventh post. At the end of the article you’ll find links to the other blog entries.
To create and use blocks and slices, you need to know the type of an element - is it a highway, a landuse or a barrier. And if it is a highway, is it a primary, a secondary or a footway.
Keys
Apart from relations where the type key stores it, this information is not available within OSM data. Again, it has to be guessed, and there is much discussion on the forums and elsewhere about the “main keys”, as they are sometimes called. Several apps, such as most OSM editors, contain such a list, but the lists are not always the same.
The approach I took was this: I counted all the keys of all the tags of all the elements and took the one that appeared most often in this list. I considered this the first main key and removed all elements with this key from the set of elements. Then I repeated this...

Try our online demonstration to find your own shade-optimized route! Discover how we improve pedestrian comfort during hot days by prioritizing shaded paths. (demo restricted to the Nantes Area)
Introduction
This project focuses on enhancing pedestrian routing in OpenStreetMap (OSM) by incorporating shade into route computations. Exposure to direct sunlight significantly affects pedestrian comfort, especially during hot weather, making shaded routes preferable even if slightly longer. Despite this importance, existing OSM data related to shade has typically been qualitative and limited in precision.
To address this, we developed and implemented two complementary methods to integrate detailed shading information into OSM-based routing engines like Graphhopper:

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

Field teams and GIS teams often seem like they speak entirely different languages. Your GIS teams rely on precise data, accurate coordinates, and timely geospatial information to guide important decisions. Field teams need straightforward, simple-to-use field data collection software that let them execute their workflows while quickly and unobtrusively capturing important data.

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.

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

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

I recently “celebrated” my “cancerversary”, the one-year mark since my GI doctor phoned me up and said the fateful words – “you have cancer”.
At that moment, my universe shrank down immensely. All the external stuff, job, professional relationships, volunteerism, just kind of fell away, I had no mental space for it. It was just me and my immediate family and the many, many unknowns.
My experience since then has included two major physical insults. The “curative” surgery that removed most of my rectum, and the associated c.difficle infection that brutally wrecked my GI tract.
The insults really knocked me back. Moving around the house involved effort. Meals would lead to stomach pain and long sessions on the toilet. Runs were replaced with walks and then shorter walks. A trip to the cafe became my gold standard for “getting out”.
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...
Every year, around 1.3 billion tons of food – nearly a third of total global food production – goes to waste (FAO). At the same time, 733 million people faced hunger in 2023, with one in five affected in Africa (WHO). It’s a painful paradox: tons of food are thrown away while millions go without.

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

You wouldn’t know it to look at me (or would you?) but I am a person who has read all 14 books of the original L. Frank Baum Oz series. From “The Wonderful Wizard of Oz” to “Glinda of Oz” and all in between.
As… that kind of person, I was truly tickled to pick up “Wicked” a couple years ago and take in not only the invented back-story of the Wicked Witch of the West (Elphaba), but also all the references to the Oz world that Maguire builds into his narrative. “Wicked” is the best kind of reimagining, one that manages a completely fresh story, but without tearing down the original source material on the way. Maguire clearly is also… that kind of person, and he treats Oz with respect while building a totally fresh...

For PostGIS Day this year I researched a little into one of my favourite topics, the history of relational databases. I feel like in general we do not pay a lot of attention to history in software development. To quote Yoda, “All his life has he looked away… to the future, to the horizon. Never his mind on where he was. Hmm? What he was doing.”
Anyways, this year I took on the topic of the early history of spatial databases in particular. There was a lot going on in the ’90s in the field, and in many ways PostGIS was a late entrant, even though it gobbled up a lot of the user base eventually.
This blog post was first published on Chris’ personal blog on February 9, 2025 and is being cross posted here.
Have you benefitted from Cloud-Optimized GeoTIFF’s? SpatioTemporal Asset Catalogs? Zarr, COPC or GeoParquet? Not just the formats, but the whole ecosystem of tools and data around it? Well I’d like to present you with an incredibly easy opportunity to ‘pay it forward’ and help build and expand the movement. And all you have to do is attend a conference! One that should be a totally awesome experience, the first in-person CNG Conference, from April 30th to May 2nd.
I have big dreams for this conference, as my hope is that it can expand in the next few years to become a truly vendor-neutral gathering for anyone working in and around geospatial data. To be one of those conferences that has the critical mass where you know ‘everyone’ you want to talk to will be there. In North America there’s really only two options for this: Esri...

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...

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...
The post discusses AI hallucination - when AI generates incorrect
information. It explores two main problems: user frustration with incorrect
outputs and uncertainty about managing these errors long-term. Using a
geodetic network analogy, it explains how AI errors can propagate like
measurement errors in surveying, suggesting we need better frameworks for
detecting and managing hallucinations.

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

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

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

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

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

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

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

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

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

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

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...
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...

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.

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.
Part 1 This is part 2 which will be pretty simple. This is more of the “get organized” part. In part 1 I was able to generate a watershed boundary from LIDAR Elevation Data. After it was generated I went back and checked the watershed line and really only found one thing that looked weird. […]

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...

In the recent edition of Key Thinkers on Space and Place edited by Mary Gilmartin, Phil Hubbard, Rob Kitchin and Sue Roberts, I was asked to write a chapter about Mike Batty. While I have known Mike for a while, to say writing the chapter was easy, is a understatement. In the sense, we had a word constraint (3,000 words plus references) and trying to sum up his biographical details and theoretical context, his spatial contributions along with his key advances and controversies, and key works was a challenge. Anyway, if you would like to read a draft of my contribution to the book and my attempt to sum up Mikes work, you can find the reference and the link to the chapter below.Full reference: Crooks, A.T.

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.

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...

So, I got the news from pathology.
There is no cancer left in me, I am officially “cured”.
Since I am still recovering from surgery and relearning what my GI tract is going to do for the future, I don’t feel entirely cured, but I do feel the weight of wondering about the future lifted off of me.

Building on Rwanda’s leadership in air quality initiatives, we’re convening local professionals, as well as experts from across Africa and around the world.
Why Rwanda?
Africa faces some of the most severe air quality challenges. Fortunately, the affordability of air quality sensors have led to improved monitoring and a wealth of data across the continent and the world. While this is a positive development, the lack of common data schemas and file formats hinders effective sharing and analysis, limiting this data’s potential to inform air quality solutions. By convening this sprint in Africa, we can leverage the expertise and perspectives of African air quality professionals to...
There may come a time in your mapping application where you need the user to identify a point of interest within a specific area. For example, having the user mark public bathrooms in a park, pinpoint hazards in a construction zone, or identify bus stops within a city. For one project at Sparkgeo, the application …

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...
My last few posts have been about applying machine learning to try to extract geographic objects in LiDAR. I think now I would like to go in another direction and talk about ways to help us find anything in LiDAR. … Continue reading →

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...
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 -...
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...
