I want to integrate a Geolocate control into a MapLibre map and customize it both visually and functionally to fit my app.
At first, I considered using the GeolocateControl that comes standard with MapLibre. However, I quickly discarded this approach because adapting it to my needs seemed too cumbersome without a lot of fiddling.
My goal is that when the button is clicked, the display of the current location is toggled—so it can be turned on and off.
MapLibre itself offers several ways to draw circles on the map, depending on whether they should be pixel-accurate or meter-accurate.
Circles on a MapLibre Map
My starting point is a simple map.

As an OpenStreetMap contributor, I’ve always been dedicated to enhancing the detail and usability of local data. Recently, however, I ran into a frustrating problem: in areas I’ve mapped, the Chinese names for many places fail to display correctly in certain applications and services (like OsmAPP, JawgMaps, and MapTiler). Instead, they either fall back to Pinyin or default to the English name (name:en), which looks odd—especially when a primary name tag clearly exists but is simply ignored.
The root of the problem lies in the peculiar rendering rules of these applications, which often prioritize name:[lang] tags that match the user’s language. Even though we add a name tag, the absence of an explicit name:zh or name:zh-Hans tag can leave the renderer confused, causing it to fall back to name:en or just display the Pinyin transliteration.
Manually adding these tags to thousands of elements is obviously out of the question. You can’t just copy and paste your way through it; the...
作为一名贡献者，我一直致力于提升本地 OSM 数据的细节和可用性。但是最近我发现一个令人困扰的问题：在我绘制过的区域，很多地点的中文名称在某些软件/服务中 (比如 OsmAPP、JawgMaps 和 MapTiler 的瓦片等）无法正确显示（回退为拼音），或是优先显示了英文名 (name:en)，导致看起来怪怪的，明明有 name 但就是不用。
主要原因这些软件的神必渲染规则通常会优先寻找符合用户语言的 name:[lang] 标签。虽然我们加了 name 标签，但如果缺少了明确的 name:zh 或 name:zh-Hans 标签，渲染器可能就会“不知所措”，转而去寻找 name:en 或干脆直接显示拼音。
手动为成千上万个要素添加这些标签显然是不现实的，又不能靠复制粘贴，一圈下来人可能都麻了。我决定靠自动化，也就是写一个脚本来解决这个问题。
技术选型与脚本逻辑
对于这种讲究高性能的操作，C++ 肯定是首选，我还用了两个强大的开源库：
pugixml: 一个以轻量和高性能著称的 C++ XML 解析库，用来极速读写庞大的 .osm 文件。
OpenCC: 社区公认的中文简繁转换标准库，用于生成 name:zh-Hant 标签。
我编写的脚本核心逻辑如下：
读取与解析: 使用 pugixml 加载从 Overpass API 查询的的本地 .osm 数据文件；
遍历要素: 循环遍历文件中的每一个 node way 和 relation；
定位目标: 检查元素是否含有 k="name" 的 tag；
生成标签: 如果找到 name 标签，则执行以下操作：
复制 name 标签的值，创建新的
I want to blog about running, but having never mentioned it on here I feel like I should give some history, so let’s go back in time….
Back in 2008 my old boss Steve Frater mentioned to me that he was planning to run a 10k race near me and would I like to join him.
I’ve just entered the Liverpool 10K on Oct 5th - that gives you plenty of time to train so how about it?
I laughed at him and said that I don’t run, I cycle, but for some reason I did start considering it and ultimately did sign up. (Looks like his original suggestion was in April and I didn’t sign up until August the 1st!) I must have caught the bug as I ended up agreeing to do a 5k race two weeks before this too.
Over the years I did keep running but I didn’t really get into a regular pace, sometimes I’d run with friends, sometimes not. I did the Santa Dash and a few other races, including the Tunnel 10k Run through the Mersey Tunnel, but at times I would still get out of the habit and would stop for a long...

To help make OSM more inclusive in line with the diversity statement https://osmfoundation.org/wiki/Diversity_Statement I’ve gone through the wiki and changed all relevant instances of specific pronouns to their gender neutral versions. This both encourages inclusivity by including non binary people, and makes the pages easier to understand.
Pages and text that have not been changed are statements by members of the community, talks, personal user pages and other related pages where changing the phrases would reflect directly on someone’s opinion.
This resulted in changes to around ~190 wiki pages, or if you include modified templates, another ~4100 pages. Below is a list of phrases I changed to their gender neutral version.

Nominatim has recently added a new kind of details to its results: entrances.
This post explains what the new feature looks like
and why that is useful.
One of the important applications for geocoding is routing: you give the
router a start and a destination address and then expect it to find a route
in between. Start and destination address are usually sent to a geocoder to
convert them into a set of coordinates. The problem here is that geocoders
and routers have a slightly different view of the world: when a geocoder is
asked for an address, it will return the building that belongs to the address.
The router on the other hand only knows about the road network. So it has
to make an educated guess on which street you actually want to start your
journey. That usually works okay for smaller buildings but when it comes
to larger structures like parks or airports the outcome might not
be what you expect:
That’s where entrances come into play. Instead of just returning the...

* route=railway : 대중교통 노선 (호남선 무궁화호 등..)
노선 (운행 계통)
선로와 노선의 차이를 잘 구분해야 합니다.
번호가 붙지 않은 노선의 ref 태그에는 노선기호의 문구(신분당선 -> 신분당) 혹은 역 번호의 앞부분을 넣는 것을 고려 (예: 용인경전철 Y1## -> Y1 혹은 Y)
정거장
public_transport=stop_area_group가 비표준 태그이기 때문에, 사용을 지양해야 합니다. 링크
하나의 역은 하나의 public_transport=stop_area 관계로 나타내어야 합니다. (노선별로 관계를 분리하지 않아야 함)
출구의 name은 숫자가 아닌 이름이 있는 경우에만 입력합니다. (번호가 붙은 출구는 name을 비우고 ref만 입력합니다)
public_transport=stop_area의 name 역시 ‘~역’을 제거합니다. (시설물로서의 역을 나타낸다기보다 정거장으로서의 역을 나타내는 경향이 크기 때문)
Ref 키 사용 정리
철도 관련 지물에 붙는 번호/코드의 종류를 정리해 보았습니다.
노선번호(대중교통): route=railway의 ref
노선번호(선로): route=train의 ref 및 railway=rail의 ref
선로번호(역 구내): railway=rail의 railway:track_ref (ref를 쓰지 않도록 합시다)
타는 곳 번호(역):
역번호: 개별 역의 ref
역명 전산약어: 개별 역의 railway:ref

Hey OSM Kerala,
I’ve recently come across these innovative “Bottle Booths” scattered across Kerala as part of the state’s push for better plastic waste management. From what I’ve gathered, they’re public recycling stations designed specifically for collecting plastic bottles to reduce littering and promote recycling. The Kochi Corporation alone has installed over 300 of them in various spots, and similar initiatives are popping up elsewhere, often tied to the Haritha Karma Sena waste collection program.
Inspired by this, I’ve started mapping them into OpenStreetMap! So far, I’ve added a few in my local area, tagging them as:
amenity=recycling
recycling_type=container
recycling:plastic_bottles=yes
Optional extras like name=Bottle Booth and operator=Local Corporation (e.g., Varkala Muncipality) if known.
I’m not entirely sure about the full benefits of mapping every single one—maybe it’ll help apps like OsmAnd or Organic Maps guide people to the nearest booth,...

I’ve been mulling over an idea for a while: what if we grab a complete snapshot of OpenStreetMap data for a given region, then run some statistics over it?
Things like which tags are most frequently used, who the top contributors are by edit count, and who has been active in that area the longest.
For the last one, “longest active” means the timespan between a contributor’s very first edit within that region and their most recent edit (also within that region). This distinction helps separate two very different contributor types: the one-hit wonders who show up during a mapping campaign, make a huge number of edits in a short burst, and then disappear forever; and the long-term caretakers, often locals, who quietly keep the map up to date whenever they notice changes in their surroundings.
To explore this idea, I had to build some tools.

I am two days late to write this post. Life gets in the way. However, I felt I should have this in writing. On 6 September 2025, after 11:30 PM, I suddenly realized that the ending day marks something significant. It marks the 10th year completion of my journey with OpenStreetMap. 10 years ago, on this day in 2015, I entered a workshop arranged by Save the Children International in Bangladesh. The workshop was arranged by a project named Kolorob (Bengali word for the sound of a lot of people cheering together) who were training youths on how to edit OpenStreetMap. Little did I know back then that it will entirely change the direction of my life.

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

Lifecycle Tagging
Lifecycle tagging is the representation of the temporal state of an object (e.g., whether it is under construction, demolished, or abandoned). Since there is no single convention universally accepted by the community, different and inconsistent schemes have developed, making automatic interpretation and uniform data management difficult. In many map editors, there is no section dedicated to editing this lifecycle, which makes it even more difficult for new users to understand how to use the system.
The goal of this project is to devise and implement a method for applying lifecycle tagging in a way that is simple, intuitive, and does not interfere with existing tagging practices.
PR can be viewed here.
Study
Before fully committing to the development of a new interface, a study was conducted to assess which tagging schema is the most popular, consistent and suitable for integration into the iD editor. Many other editors have been. Full study available here.

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.

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.

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.

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...

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

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

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

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.

A discussion of geo and 'zines with members of the Geozone collective (for our 20th anniversary)
Running together at CNG Conference 2025
On the last day of CNG Conference, we held a facilitated discussion to identify what our community needs to thrive.
As Chris Holmes noted in his opening keynote, the geospatial field has reached a pivotal moment. We have more data, better tools, and greater computational power than ever before. The question now is how we use these resources to address real-world challenges. The six themes below emerged from our discussions and will shape our collective work in the coming year.
These challenges are deeply interconnected. Progress in one area often enables progress in others. And with AI rapidly changing the landscape, we need to stay adaptable and collaborative. We invite governments, funders, educators, enterprises, and entrepreneurs to join our community in this ongoing effort.

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

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.

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

I have just gotten back from attending the 19th International Conference on Computational Urban Planning and Urban Management (CUPUM) in London and thought I would share the two papers we presented at the conference. The first paper was with Qingqing Chen and Linda See and was entitled "Using New Sources of Data for Urban Climate Modeling Generated through MLLMs on Street View Imagery. "As the title might suggest, this paper was about how one can leverage multi-modal large language models (MLLMs) to extract information on building height, age and function from street level photographs. We demonstrate this using street view images from Mapillary and than ask ChatGPT to estimate the building height, age and function and compare the results to authoritative data sources. If this sounds of interest, below you can see the abstract to the paper, some if the figures (i.e., the work flow and prompts) while the results can be seen in the attached paper (see the link below).

Open source geospatial 3D innovation has just reached another important milestone, thanks to a Cesium Ecosystem Grant for a new 3D globe view in QGIS. This is the second grant that the team of North Road and Lutra Consulting received from Cesium, and we’re proud of what we’ve delivered for our QGIS users. The new 3D globe will be available to all in QGIS v.3.44. This was an extremely interesting project to undertake, as it required a heavy research and experimentation process by our developers. There’s many potential approaches for implementing a large-scale, 3D globe, and each have their advantages and trade-offs. We were very lucky to have insight from Cesium’s Kevin Ring to advise us at the start […]

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

Last week, Switzerland’s Birchgletscher collapsed and caused a major rock avalanches, altering the landscape and burying the village of Blatten. With the data of the federal Rapid Mapping service and the help of individual experts, a first open post-event elevation model was made available. I used the model to create pre- and post-event visualizations and prints at a local scale.
Artificial intelligence is rapidly redrawing the boundaries of the
geospatial industry, unlocking powerful new insights and efficiencies at an
unprecedented scale. Yet, beneath the veneer of technological marvel and
the often-touted narrative of 'AI augmentation,' a more profound and
unsettling transformation is underway for its workforce. This investigation
delves into the stark realities of how AI and machine learning are not just
reshaping, but in many cases, actively replacing traditional geospatial
roles, forcing a critical reevaluation of skills, careers, and the very
future of human expertise in mapping and understanding our world. As the AI
wave crests, the line between assistant and successor is becoming
increasingly, and for some, alarmingly, clear.

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

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

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

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.

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

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

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

Full conference details can be found at the end of this email.Abstract for the Special Track: Recent developments in the use of large language models (LLMs) offer exciting opportunities to control agent behaviour in potentially more realistic and nuanced ways than has previously been possible. However, an LLM-backed agent can only interface with their surroundings through text prompts, which is severely limiting. The integration of large language models (LLMs) and geospatial foundation models (GFMs) presents an exciting opportunity to use AI techniques to advance agent-based modelling for spatial applications, potentially allowing for agents with more comprehensive behavioural realism, as well as an improved...

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. By employing natural language processing (NLP) and geoparsing techniques, we identify key topics related to the pandemic and...

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.

'POLYGON((0 0, 1 0, 1 1, 0 1, 0 0))',

))

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...
The integration of Artificial Intelligence (AI) into geospatial technology is fundamentally reshaping industries, from urban development and environmental conservation to logistics and disaster relief.

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...

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

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

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...

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."

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...

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...

We are excited to announce the founding CNG Editorial Board, a group of leaders in our community who have graciously volunteered to guide our work. The experience and good judgment of our board helps us identify new technologies on the horizon and what fads can we safely ignore as we create our events and content.
The editorial board is also designed to provide opportunities for visibility and leadership to our community members. Half of the CNG editorial board will be replaced every 12 months with new members selected by the existing editorial board. This will allow us to gain expertise from more people throughout our community and support emerging leaders.
We are immensely grateful to our board for their support as we build CNG together.

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 […]

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...

Lineage distribution of SARS-CoV-2 across geographic regions of Ontario, Canada, Western New York, and New York City over timeIn the past we have posted on using agent-based models for explore the spread of diseases. We have been keeping up with this work especially in light of COVID-19. To this end we are excited to introduce our new paper entitled "Genomic Profiling and Spatial SEIR Modeling of COVID-19 Transmission in Western New York" published in Frontiers in Microbiology" In this paper have been collaborating with other researchers at the University at Buffalo who focus on the genomic sequencing of various lineages distribution of SARS-CoV-2. What is special about this new paper is that we explore how such linages change over space and time and how this relates to movement patterns. If this sounds of interest, below you can read the abstract of the paper, see some the lineages in different regions which change over space and time, and our agent-based model which explores how...

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...

In May last year, we announced the “Cloud-Native Geospatial Foundation” as an initiative to “help people adopt patterns and best practices for efficiently sharing Earth science data on the Internet using a cloud-native approach.”
Since then, we’ve done quite a bit.
We’ve published 29 blog posts and quickly attracted over 1,000 followers on X. We created a new Slack workspace which has over 400 members and 200 monthly active users. Combined with some of Radiant Earth’s previously created online channels, we now have a social media following of over 6,000 across X, LinkedIn, and Medium, and our quarterly newsletter has over 8,000 subscribers.
We have hosted in-person sprints for Zarr, STAC, and GeoParquet. We’ve been a part of the first SatCamp, the ESIP 2023 Summer and Winter Meeting Cloud Computing sessions, and convened a two-day workshop in Rwanda focused on improving access to air quality data throughout Africa.
