Mature Wireless Sensor Networks (WSNs), or "motes," are the missing link in modern intelligence and ISR operations. This article argues the intelligence community's failure to adopt this mature technology is a critical strategic lapse , creating a "static-data trap". Discover why the problem isn't the technology but institutional lag , and explore a framework for integrating WSNs with COTS GEOINT platforms to finally achieve continuous, real-time situational awareness.

World Map Projections The theme for day three of the #30DayMapChallenge is Polygons. For this theme I've created a map that visualizes a map of the world using five different map projections.Maps shape how we see the world. Depending on the projection used, continents and countries can appear stretched, squashed, or rotated in surprising ways. This interactive map lets you explore five

From October 14-16, the STAC and Zarr communities came together at ESA ESRIN in Frascati, Italy, for the first-ever STAC sprint in Europe focused on advancing cloud-native multidimensional geospatial data. After three intensive days of collaborative development, we’re excited to share what we accomplished and what we hope to be the path forward for STAC-Zarr integration. Participants gathered at ESA ESRIN for the first European STAC sprint A Community Comes Together Twenty-six developers from across Europe and beyond converged on ESA’s facility in Frascati, representing a remarkable cross-section of the geospatial data community. Organizations including ESA, CEDA, DLR, EODC, Eurac Research, CloudFerro, Terradue, Element 84, Development Seed, DKRZ, Tilebox, and many others brought their unique perspectives and expertise to hammer out how multidimensional data should be represented in STAC. What made this sprint...

I seem to have started on the questionable task of adding all the bus routes in Halifax. I’ve been grabbing the route description from the Halifax Transit website, creating the route relations via Id and then adding to the relation with OSM Simple Route Editor. (I’d prefer to use OSM Relatify, but it seems to take a while to notice that the relation has been created or is having some other issue.) I have been using Relatify to verify that the route is correctly ordered and connected. I have also used the sort feature in JOSM “PT Assistant” plugin to deal with grumpy route alignment. I have been doing inbound and outbound legs of the bus route as separate routes to avoid the complications from using the same way twice. In the case of the 1, they were already split like that with a master route that joined the two which seems rather elegant. But, it may be worth seeing if there is a way to join the halves together after the fact. Here’s the overpass-turbo query I cobbled...

23/10/2025-29/10/2025 [1] New OSM file format: 30% smaller than PBF, 5x faster to import | map data © by OpenStreetMap Contributors. Mapping campaigns With the development of the Bliesgau region as a ‘Quality Region for Hiking in Germany’, the hiking trail network has been completely revamped in recent years. Due to the removal and replacement of signs, there is a lot of data in OSM that is no longer up to date. Together with Thomas Froitzheim, who co-developed the nationwide, OSM-compliant ‘Route 3.0’ project, some people have spent the past few months analysing the actual status, looking at which routes need to be deleted and which need to be added. This data is now available in a standardised format, including route logos, and can be maintained in OSM with immediate effect. Community Boramalper has opened a discussion on the OSM Community forum to consider founding a new free and open-source service for crowdsourced user reviews of Places of Interest in...

Day two of the 30 day map challenege is lines! A few weeks ago I wrote a post about stream traversal with SedonaDB. For day two I’ll do this with the river system for Gaspereau Lake (starting at the mouth of the beautiful Gaspereau River!). For anybody not familiar with the Gaspereau River, it features excellent wineries and the best tubing this side of any line you draw. Let’s get to it! # pip install "apache-sedona[db]" import sedona.db sd = sedona.db.connect() sd.options.interactive = True Let’s get ourselves some data! I’ll use the same GeoParquet as in the last post, but while in the last post I downloaded it using curl, I’ve since realized that SedonaDB can load it straight from the http url in a few seconds. I’ll augment the segments right out of the gate with the start/end points…the feature code list I had to iterate on a bit because the Gaspereau River system has a few fun hydrological components I hadn’t spotted in the last post (notably: canals, flumes, dams, and coastal...

Koh Phangan is one of Thailand’s most enchanting islands, floating gracefully in the Gulf of Thailand between its famous neighbors, Koh Samui and Koh Tao. Known for its palm-fringed beaches, lush jungles, and vibrant culture, Koh Phangan is far more than just the site of the world-renowned Full Moon Party - it’s an island with a fascinating geological and cultural history shaped by magma, time, and the sea. Millions of years ago, long before travelers set foot on its shores, the land that became Koh Phangan was formed deep within the Earth’s crust. The island originated from volcanic activity during a period of intense tectonic movement. As magma rose from beneath the Earth’s surface, it cooled and solidified, giving birth to the island’s granite core. That foundation still defines its rugged mountains and dramatic rock formations today. Over millennia, erosion, wind, and the gentle rise and fall of sea levels sculpted the island into its present form. The lush jungle that now...

我主要绘制地图的地方都是我熟悉的地段。伦敦的地图早已细致得无可挑剔，我所能做的，不过是依照自己的实地探访，添几笔修补与更新。而那些我真正想描绘的地方——韶关、狮山——在地图上却几乎是一片空白。于是我盯着卫星影像，凭借记忆，一条一条地把它们补上去。 然而，一旦动笔，记忆便被无声地唤醒。 狮山的郊外，是满目灰尘与机器轰鸣的工业区。但在那段短暂的大四下学期——也正是中国放开三年疫情封控的时节——我几乎把所有空闲都花在漫步上。我终于能重新走出校门。那是一种久违的自由，也是一种怅然的陌生。我在风尘漫天的乡村与工业区之间走走停停，感受空气、阳光，还有一种模糊的“重生”的气息。如今每当我在地图上画下那一条条路，心里都能重新浮现当时看到的一切：斜阳下的厂房、贴着褪色标语的围墙、被工厂分割得七零八落的农田…… 狮山的城区，则是我课余时常去的地方。几个广场、几座公园，见证了太多微小却清晰的瞬间——我记得每一次同行的人，记得谈笑的片段，甚至记得那时吹过的风。 而狮山大学城，那更不必说。四年光阴的流动，几乎都沉淀在那片土地上。无数的晨昏交替、无数未完的对话、无数被时间吞没的小事——都化作我记忆的一部分。 再往前追溯，就是韶关，我的故乡。那座夹在群山之间的袖珍小城，从小到大承载了太多我的生活。每一条街道、每一个转角，都藏着旧日的故事。那是一个人生命中最初的坐标，是无论走多远都无法抹去的印记。 所以，当我坐在远在数千公里外的伦敦，往这些空白的区域绘图的时候，心里总会冒出一个问题： ——我到底该留在哪里？ 年初的时候，我曾以为这一年会让我找到答案。但时至今日，犹豫仍在。 文化上，我当然认同留在广东。嗰度嘅语言、食物、人情，都系我最熟悉、最舒服嘅空气。 可与此同时，也有些记忆在暗暗提醒我：不要回去。那些过去几年留下的痕迹——恐惧、疏离、无力感——仍像一层薄雾，笼罩在记忆的上空。我怀念那片土地，也被它深深刺痛。 ​I love my country, but not the party. 我爱这片土地，也爱生活在其上的人们。 但那份爱并不来自，也不属于盘踞在那片土地之上的权力、旗帜，与口号。 也许我找不到一个可以真正安放自己的地方。但我希望，那些我亲手画下的线，能在虚拟二维的OpenStreetMap里，延续我对故土最温柔的告白。

Não gosto muito de falar em público ou coisa assim mas me deu vontade então vou falar coisas Eu sou nativo de Florianópolis e morei minha vida inteira aqui, tirando a única vez que eu tive uma pousada em São josé. Desde pequeno eu fui muito interessado sobre geografia. Bom, o Openstreetmap basicamente foi um portal abrindo por que o maps ele é cheio de erros e o OSM parecia o céu dos mapas. E é, só que como tudo, não é perfeito. Igual a organização geográfica de Florianópolis. Só pra vcs terem noção ela virou municipio no final dos 1726 e é cidade desde 1600 e coisa coisa, e só em 1999 fizeram os primeiros bairros. Isso é 300 anos sem bairros oficiais. E só agora tão oficializando as localidades.. Algo que eu percebi é que tem uns erros aqui no OSM de Florianópolis, como, a Tapera da Base pega a UEP Morro do Peralta, sendo que, de acordo com a lei, não pega, deveria ser parte do Carianos. Quer dizer, Carianos nem deveria tar com mapa, POR QUE NEM É BAIRRO IGUAL TUDO EXCETO A...

Some news and visions about topic focused contribution monitoring capabilities of ProjetDuMois ProjetDuMois platform For more than 6 years, ProjetDuMois platform was used to plan, encourage and monitor “Projects of the month” by French community (and some other countries too). It has been a significant progress for people responsible of those very short projects as it has freed us from the hassle of counting changesets and provides a mappers-friendly customized editor. It relies on daily OSH/OSC files processing to extract history of filtered features, rebuild focused changelog from a remote date in the past and breakdown changes in dashboards at different custom geographical boundaries (usually administrative boundaries). It somehow differs from other approaches intended to inspect OSM contribution like HeiGIT’s OSHDB. Here all features and their history related to a given project is first of all extracted from the OSH file and then dedicated process occurs on a smaller...

出于个人的隐私考虑，本人的 OpenStreetMap 账户的用户名使用化名，敬请谅解。 简介&来意 我是一名陕西省咸阳市的中学生，在探索开源软件的过程中遇到了 Organic Maps、CoMaps 和 OsmAnd~，并认识了 OpenStreetMap。由于对开源软件的热爱，以及发现 OpenStreetMap 对中国大陆的小城市（包括我居住的城市）的数据支持不够完善，因此想做出一些贡献，用这种方式帮助自己身边的人以及需要的人（虽然周围的人没有一个知道 OpenStreetMap，但是万一他们哪一天需要呢） 一直以来，坐标系统的不一致导致 Google 地图和其他海外地图在中国大陆的卫星影像和人工标注的道路信息差了上百米，国内的地图软件对国外的数据支持也有限，更重要的是国内外主流的地图产品出于商业考虑不向公众共享地图数据，OpenStreetMap 在这一点上无疑是很好的开源替代品。但其在中国大陆（在国外也可能符合这个规律）的地图数据的详细程度大致与这个地区的经济发展状况成正比关系（正常，商业地图公司的员工开车全国跑，地图数据也要详细的多），这容易让人误解：某个地方除了道路什么也没有。 编辑地图只是出于我对开源软件和开放数据的热爱，而且也不是我的正事，因此我每天不会花太多时间在这件事上。 事件 在 2025 年 10 月 29 日，我收到了贡献者 booktiger 发送的一封欢迎消息，并且阅读并了解了中国的法律情况和编辑指南（说实话我只是想完善一下居民区建筑信息以及店铺信息，我连监狱都不想往上画，更不要说国家机密了），也阅读了他参与的一些讨论（比如 397559）。 本人对政治并不感兴趣，但这并不意味着本人没有一点政治常识。对于台湾问题，我很庆幸 OpenStreetMap 上没有标注国界线，这避免了许多潜在的争议（虽然一些人将水陆分界线当成了国界线并且发表自己的意见，比如 395824）。但是如果你因为 OpenStreetMap 没有给“台湾”后面加“省”感到特别生气，也可以在网络上发表自己的意见。我绝不会干涉任何一方的言论自由，而且也不会修改台湾（省）本地的任何信息。

Day one of the 30 day map challenege is points! One of the datasets I use all the time in testing is named ns-water_point from GeoArrow Data. When I made this test data I didn’t think very hard about it…the Nova Scotia Geospatial Data Directory has a hydrological section and I spent the better part of a decade there working on lakes…it seemed like fun! Other than a few sanity checks I never really looked at the data, though, even though I read in the points one all the time as an example because it’s the smallest. Day one of the 30 day map challenege seemed like a good time to resolve this. What is ns-water_point, anyway!? Let’s roll. I’ll be using SedonaDB, so let’s load it: # pip install "apache-sedona[db]" import sedona.db sd = sedona.db.connect() sd.options.interactive = True Next, let’s get the GeoParquet url from the GeoArrow Data page: url = "https://github.com/geoarrow/geoarrow-data/releases/download/v0.2.0/ns-water_water-point_geo.parquet" Next I’ll read it in as a view....

Daniel O’Donohue, host of the #MapScaping Podcast, reflects on how access to tools no longer defines expertise in his piece, “Cameras, GIS, and why tools don’t make you special anymore”. As #AI lowers technical barriers, he argues that what truly sets professionals apart is not tool mastery but vision, a stance, and the ability to interpret and critique.

這篇是拖了一段時間的參與心得，先從比較有官方色彩的開放街圖基金會的相關記錄與討論開始，再來比較個人的交流與觀察。 大會第三天在閉幕式前的 OSMF 時段，由具備理事身份的人座談。OSMF理事長談到一些花費是這麼說的，大家覺得努力募款增加捐款數字，但目前很多幫助來自業者服務捐贈，如CDN、Bing衛星圖、伺服器等，如果任何業者決定中止捐增，會導致 OSMF 有很嚴重的財務缺口。而圖客參與畫地圖才能一直維持地圖的活力，所以社群經營也是重要的挑戰。理事Otris提到，他們目前重點是讓硬體設備能支援未來的需求，很努力進行開發與硬體架構設備。 OSM Award Brandon 被提名，然後他們自己不知道，他開完笑說知道他被提名還可以拉一些票，再來是多位獲獎者不在現場，需要由人代領。 https://awards.openstreetmap.org/ HOT 主力的大會 這次以HOT Asia Pacific Map Guru身份參與State of the Map 2025大會，不只是講者的身份，或是地方社群組織者，還有HOT身份，有點汗顏台灣不是HOT AP優先區域，也不大需要靠OpenStreetMap去成為救災主力圖資。 ## 東亞與南亞社群的聯結 我再次遇到韓國社群的成員，先前在台灣時已經在COSCUP遇到他了，鼓勵南韓的Dong Hwang也可以參與HOT相關訓練課程，其內容都蠻實用的。 從日本社群的古橋大地桑聽到PLATEAU建築資料集的故事，原來背後推動人士瞭解社群，知道怎麼調和彼此關注之處，從而引路社群機制來共同編輯資料集。 與印度社群交流，他們也有類似台灣弄學校資料的整理，由於關注度因素得弄獨立的MediaWiki站，然後他們不同單位有不同代碼，不只需要弄一個代碼。 台灣經驗分享 這次演講題目細數台灣曾經做過的專案，談論將OpenStreetMap與Wikidata彼此連結的經驗。儘管我沒太講工具的部分，但有口頭講在維基媒體生態系的工具生態系較成熟，有運用在Wikidata上的自動表格工具Listeria，監控Wikidata上即時的項目，例如所有台灣的國中小、教會、廟宇、村里行政區之類。目前 OpenStreetMap 上面則沒有太好用的監控維護工具，所以得依整先在 Wikidata 上確定資料完整，再回過頭檢查...

GIS mjesec osm-hr 112 Dan GIS-a (GIS Day) slavi se svake srijede unutar Geography Awareness Week kako bi se istaknula važnost geografskih informacijskih sustava u obrazovanju, industriji i javnom sektoru. Ove godine je to 19.11.2025. i tijekom tog dana organiziraju se demonstracije, radionice i prezentacije koje pokazuju kako GIS pomaže u planiranju grada, upravljanju resursima i donošenju odluka temeljenih na prostoru. OpenStreetMap predstavlja dobar primjer otvorenog, zajednički stvaranog kartografskog projekta koji se često koristi kao izvor podataka u GIS projektima. Korištenje OpenStreetMap podataka i drugih otvorenih podataka u GIS-u potiče transparentnost i suradnju te pomaže bolje razumjeti i upravljati prostorom oko nas. Proširenje GIS Day akcije na OpenStreetMap aktivnost mapiranja tijekom cijelog GIS mjeseca može donijeti dugoročniji učinak, jer se stvaranje i ažuriranje otvorenih podataka prenosi iz jednokratnog događaja u kontinuiranu zajedničku aktivnost.

Český Krumlov stojí před rozhodnutím, které zdaleka není jen technické. Postavit severní obchvat, anebo hledat jiná řešení dopravní zátěže? Na první pohled jde o jasný krok. Odvést tranzit mimo město. Jenže realita krajiny, chráněných území a členitého terénu ukazuje, že nic takového nejde udělat bez následků. Severní svahy města přecházejí do CHKO Blanský les a přírodního parku Cvičák, kde každý zásah znamená dlouhodobou změnu charakteru krajiny. Městská varianta trasy zas počítá s tunelem, který by stavbu významně prodražil.

This is the story of how the cycling association measured streets in Bruges and got what they wanted - a cycling zone - 5 years after the initial campaign… The setup First some belgian road law. One of the peculariaties of Belgian is that we have the concept of a ‘cyclestreet’. This is a street where cars are not allowed to overtake cyclists - one of the tools to make cities more liveable. A cycle zone is similar, except that it is about multiple streets. It needs different traffic signs and is in effect until the “end of cycle zone”-traffic sign. The cycling association of Bruges wanted a cycling zone in the entire city center. To force this, they devised a plan using a different law. The Belgian road code says that cars are not allowed to overtake a cyclist if the space between a cyclist and the car would be less then 1 meter. In other words, if the cycling association could prove that most of the streets in Bruges are too small to legally overtake cyclists anyway, that...

Há algum tempo estabeleci para mim mesmo um desafio ousado: registrar pelo menos um changeset em cada país/região listada no OpenStreetMap. Eu me baseei na lista oficial do OSMstats, composta por 260 locais ao redor do mundo — e hoje posso dizer que o desafio foi concluído. O mais interessante dessa jornada foi perceber como o mundo é diverso até no mapa. Em alguns locais, o mapeamento está tão detalhado que foi muito difícil encontrar algo para contribuir. Já em outros… praticamente tudo ainda precisa ser mapeado — sem falar na falta de imagens de boa qualidade para servir de referência. No fim das contas, foi muito mais do que completar um checklist. Foi uma viagem virtual pelo planeta, enxergando paisagens mapeadas e não mapeadas, contrastes culturais e diferentes níveis de engajamento da comunidade. E é exatamente isso que torna o OpenStreetMap tão especial. Cada contribuição, por menor que pareça, faz o mundo ficar um pouquinho mais visível. Agora é pensar no próximo...

I have been mapping addresses on OpenStreetMap since a long time. During this time I have been also frequently referring to the wiki page for guidance whenever I felt my method was wrong. This post is the result of all the stupid mistakes I found during this checking of wiki. I hope that others wouldn’t make those same stupid mistakes. Though this post is based on my experience in India, it should be useful to people elsewhere in the world. The mapping process looks like this: Check if the neighbourhood or the street is present on the map. If it’s not, then add it. Create the building if it’s not on the map. Then add addr:street (or addr:place) and addr:housenumber (or addr:housename) to the building depending on the address. That’s it. Now let’s elaborate on some things. Point (1) is not something which is mentioned frequently but which is needed if you want to use your addresses in apps like OsmAnd in a proper fashion. So, start adding those name to the roads...

When I was using JOSM tonight, the satellite imagery shown on my screen reminded me of something. It reminded me of a simulation game I loved playing several years ago : SimCity 4. JOSM and that game share many similarities. At first, both display satellite imagery. Then, you can draw residential, industrial, and commercial zones. You can place various amenities, draw different types of roads (from small paths to multilane highways), railways, power infrastructure, waste management facilities, airports, seaports, forests, orchards, etc..

A partire da questa domanda sul gruppo Telegram, mi è venuto in mente che fosse utile creare un breve tutorial per spiegare come visualizzare le informazioni delle direzioni all’interno delle applicazioni per modificare OpenStreetMap, che è un argomento, a mio avviso, semplice, ma poco intuitivo per i neofiti del progetto. Non tutti i nodi hanno bisogno una direzione! Solitamente, i nodi legati a una way possono avere una direzione. Questo perché in OSM le way hanno un senso di costruzione (che viene generalmente indicato con delle freccette sulla way).

Dear Bilbo, What a calamity! Just this morning, I attempted to properly document Sandyman’s Mill in OpenStreetMap—you know, the watermill where they grind all the Shire’s grain—and I discovered to my absolute horror that OSM has no proper tagging schema for Shire watermills! Oh, they have man_made=watermill for those dreadfully generic watermills elsewhere in Middle-earth, but nothing that captures the essential hobbitish details: the number of grinding stones, the undershot versus overshot wheel configuration, or most importantly, the weekly flour production capacity (measured in seed-cake equivalents, naturally). I sat there at my mapping desk, GPS coordinates at the ready (SY 1234 5678, if you must know), completely flummoxed—rather like the time Bilbo tried to explain his Elvish poetry to the Gaffer. Looks up with determined gleam in eye I realize I must take matters into my own furry-footed hands! If the wider OpenStreetMap community hasn’t created proper specifications...

When processing places of worship for the National Crisis Center (Belgium), I run into the problem that it’s quite hard to filter just “significant” places of worship from OSM. We’re interested in places where it’s likely that regular services take place, or that get regular crowds (e.g. weddings & funerals). But it’s hard to remove all the little wayside crosses or chapels that are just not relevant because their tagging is too limited. uMap with all the places of worship that could not be classified To do so, we start from all places with amenity=place_of_worship. For our search area (Belgium + areas we have projects in + a buffer), that give us about 45.000 locations. My initial strategy was to then exclude “obviously small places”. There’s three tags we can use for that: place_of_worship (and the deprecated but still used place_of_worship:type) building (and building:part) which gives an idea of the function of the building historic, which is often used to...

I had the incredible opportunity to represent Vriddhi Project – UNOPS Sri Lanka at the State of the Map 2025 Conference, where I presented a talk on “Mapping for Impact: Introducing Open Mapping to Civil Society in Sri Lanka.” During this session, I shared how Vriddhi Project empowers civil society organizations (CSOs) across Sri Lanka to harness data and geospatial technologies for better advocacy, planning, and community engagement. Civil society often faces challenges in visualizing, analyzing, and applying data effectively. Geospatial tools allow CSOs to map resources, identify gaps, track progress, and communicate evidence-based solutions, amplifying their impact at the grassroots level. The session resonated strongly with the audience because it highlighted real-life applications, measurable results, and the transformative power of open mapping. Participants were inspired to see how geospatial tools can turn abstract data into actionable insights that drive social...

I had the incredible opportunity to represent Vriddhi Project – UNOPS Sri Lanka at the State of the Map 2025, held in Manila, Philippines from October 3rd to 5th, 2025. As part of this global gathering of open mapping enthusiasts, I conducted a hands-on workshop titled “Getting Started with QGIS: Beginner’s Guide to Mapping with Open Source Tools.” The session introduced participants to the exciting world of open geospatial technology and its potential to create positive impact at community level. During the workshop, we explored: - OpenStreetMap (OSM) and the HOT Tasking Manager for collaborative and humanitarian mapping. - Open data sources such as Planet OSM, Geofabrik, BBBike, and Overpass Turbo. - How to select the right data type, perform data cleaning, and integrate datasets into QGIS effectively. - Practical mapping exercises that turned open data into meaningful stories and insights. The energy in the room was inspiring — participants from different backgrounds came...

I’m an obvious fan of GeoParquet and SedonaDB and it should be no surprise that I worked (still working!) pretty hard making sure SedonaDB could take advantage of all GeoParquet had to offer. This post talks about one of those things: lazy reads (or if you’re a databse nut, “pruning”). Basically, GeoParquet was designed to allow traditional GIS software to take advantage of a decade plus of heavy investment in the Parquet format and the software that reads and writes it. Two spot examples are that (1) software that reads traditional GIS formats is not particularly good at splitting the work up so that all the cores on your computer are put to good use and (2) most formats are not particularly good at being plonked onto a web server and have sections of them selectively queried1 (which can often save data producers from standing up a 24/7 web service). FlatGeoBuf, of course, is the shining example of being great at being plonked onto a web server in this way and it’s great as long as...

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

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?

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

The premise of this editorial is that Generative AI (GenAI) is impacting all aspects of our daily lives and as such has we were wondering how will it impact urban modeling? For example, in the editorial we discuss how  GenAI could speed up the overall urban modeling process. To demonstrate this we show how ChatGPT (and its built-in coding interface Canvas) can take published papers and build agent-based models from them (one being of an abstract space and another being spatially explicit). However, while model building is time consuming task, another challenge modelers face is how to incorporate decision making within them. To this end we also discuss how large language models (LLMs) have the potential to help with  agent-decision making in the form of generating  agent-personas or scheduling agent activities. We conclude the...

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

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

The way we observe our planet from orbit is undergoing a seismic shift, moving beyond the limitations of traditional satellite tasking to embrace a future of intelligent, interconnected Earth observation. This revolution is powered by the synergy of "virtual constellations" – diverse networks of coordinated sensors – and sophisticated "tipping and cueing" workflows, where broad-area monitoring by some assets automatically directs high-resolution satellites to points of critical interest. Underpinning this entire evolution is the transformative power of Artificial Intelligence, which not only automates the detection of subtle changes and orchestrates complex tasking but also distills vast streams of imagery into actionable insights, promising a more transparent, responsive, and understandable world.

One of our goals at CNG is to create a larger and more diverse community of geospatial data practitioners. While tremendous progress is being made to make geospatial data easier to access and use in the cloud, we know that there are many people in need of training and educational opportunities to benefit from this progress. To this end, we are starting to experiment with issuing badges to recognize individuals who have completed cloud-native geospatial trainings. We have started by partnering with thriveGEO, a training and technical consulting company based in Germany. In April 2025, thriveGEO gave its first Cloud-Native Geospatial 101 training course and we have issued CNG Badges to course participants. CNG Badges use the Open Badges Specification which allows us to give people a verifiable digital credential that asserts they have completed a CNG-approved training course. By maintaining a vendor-neutral view of the geospatial technology landscape, we seek to...

In the past we have explored how social media can be used to delineate earthquakes, study human-wildlife interactions, understand urban morphology, urban smells or  locating wildfires among many other things. Keeping with the last topic (i.e., locating things), in a new paper published in GeoJournal entitled "Crowdsourcing dust storms in the United States utilizing social media data," Stuart Evans, Festus Adegbola and myself explore how we can use X (formerly Twitter) and Flickr  to source observations of windblown dust. As such the paper demonstrates how social media data can act as supplementary source for dust events monitoring and captures the seasonal trends of such events. Furthermore, the paper highlights the potential of using crowdsourced data for the often overlooked field of dust monitoring that has substantial health and economic impacts. If this sounds of interest, below we provide the abstract to the paper along with some figures which showcase our methodology and...

A stark vision for America's fiscal future now casts an ominous shadow, as the proposed Fiscal Year 2026 budget threatens a veritable demolition of non-defense federal capabilities, launching an unprecedented assault on the agencies underpinning our nation's world-leading geospatial infrastructure with a staggering $163 billion targeted for removal from base non-defense spending . This plan strikes at the heart of essential government functions, and even as it calls for "unprecedented increases for defense" , the National Geospatial-Intelligence Agency (NGA) faces a deep paradox: its direct appropriations may rise, but devastating cuts to civilian partners like NOAA, NASA, and USGS threaten to hamstring its operational effectiveness, potentially forcing NGA to divert its own increased budget to backfill widening data gaps and maintain "GEOINT Supremacy" with a critically weakened foundational support system. The reverberations are already palpable, and as the...

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.

Coral restoration and the realities of tech in climate fieldwork

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.

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

Cloud-Native Geospatial is quietly revolutionizing geospatial data

A few weeks ago, I posed a simple yet thought-provoking question to the geospatial community on LinkedIn, one that many found difficult to answer, including myself:

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

Simple facts about the new Cloud-Native Geospatial hype.

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

Back to entry 1 I recently “celebrated” my “cancerversary”, the one-year mark since my GI doctor phoned me up and said the fateful words – “you have cancer”. At that moment, my universe shrank down immensely. All the external stuff, job, professional relationships, volunteerism, just kind of fell away, I had no mental space for it. It was just me and my immediate family and the many, many unknowns. My experience since then has included two major physical insults. The “curative” surgery that removed most of my rectum, and the associated c.difficle infection that brutally wrecked my GI tract. The insults really knocked me back. Moving around the house involved effort. Meals would lead to stomach pain and long sessions on the toilet. Runs were replaced with walks and then shorter walks. A trip to the cafe became my gold standard for “getting out”. Now, I am immensely “better” than I was this summer. But I am still a very long way from the physical condition I was before (which was...

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...

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

For PostGIS Day this year I researched a little into one of my favourite topics, the history of relational databases. I feel like in general we do not pay a lot of attention to history in software development. To quote Yoda, “All his life has he looked away… to the future, to the horizon. Never his mind on where he was. Hmm? What he was doing.” Anyways, this year I took on the topic of the early history of spatial databases in particular. There was a lot going on in the ’90s in the field, and in many ways PostGIS was a late entrant, even though it gobbled up a lot of the user base eventually.

In previous posts we have noted how one can explore urban issues through newspapers, while at the same time we have used social media to explore trends in vaccinations. In a recently published paper in PLOS Digital Health entitled "From print to perspective: A mixed-method analysis of the convergence and divergence of COVID-19 topics in newspapers and interviews" with Qingqing Chen, Adam Sullivan, Jennifer Surtees, Laurene Tumiel-Berhalter and myself, we thought we would explore how COVID-19 was reported in newspapers and how this varied from interviews. The rationale behind this was that the COVID-19 pandemic has led to diverse experiences influenced by public health measures like lockdowns and social distancing. To explore these dynamics, we introduce a novel ’big-thick’ data approach that integrates extensive U.S. newspaper data with detailed interviews. By employing natural language processing (NLP) and geoparsing techniques, we identify key topics related to the pandemic and...

Cloud-Native Geospatial represents a significant shift in how geospatial data is processed, stored, and analyzed. This approach offers GIS Professionals greater scalability, allowing them to handle massive datasets without relying on traditional and often limited on-premise infrastructure. Additionally, the cloud-native approach enhances collaboration by enabling multiple users to access and work on shared datasets in real-time, regardless of their physical location, helping to eliminate data silos. This level of accessibility and flexibility empowers GIS professionals to deliver faster results, streamline workflows, and adapt to the growing demands of modern geospatial applications. What is Cloud-Native Geospatial? Cloud-native geospatial refers to the practice of leveraging cloud-based technologies and architectures to handle geospatial data in the cloud, ideally without migrating it between heavy/purpose-built storage and file formats. This approach focuses on...

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...

I have been watching the codification of spatial data types into GeoParquet and now GeoIceberg with some interest, since the work is near and dear to my heart. Writing a disk serialization for PostGIS is basically an act of format standardization – albeit a standard with only one consumer – and many of the same issues that the Parquet and Iceberg implementations are thinking about are ones I dealt with too. Here is an easy one: if you are going to use well-known binary for your serialiation (as GeoPackage, and GeoParquet do) you have to wrestle with the fact that the ISO/OGC standard for WKB does not describe a standard way to represent empty geometries. Empty geometries come up frequently in the OGC/ISO standards, and they are simple to generate in real operations – just subtract a big thing from a small thing. SELECT ST_AsText(ST_Difference( 'POLYGON((0 0, 1 0, 1 1, 0 1, 0 0))', 'POLYGON((-1 -1, 3 -1, 3 3, -1 3, -1 -1))' )) If you have a data set and are running...

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.

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...

One of the most fun parts of being involved in GeoParquet is that I get to hear about all the amazing tools that people are writing to scale geospatial analysis above and beyond what the stack I’m familiar with can handle. GeoPandas (Python) and sf (R) are great tools but the struggle to scale as you approach the available memory on your laptop. On the other hand, Arrow, DuckDB, Polars, DataFusion, and the other new fangled databases struggle to efficiently handle spatial joins (although perhaps by the time I’m done writing this post or by the time you are reading it, this will have changed!). Apache Sedona sits at the intersection of these technologies, joining PostGIS as a go-to tool to reach for as data gets big and you need the streaming capabilities of a database alongside index-assisted spatial-aware joins. Instead of extending PostgreSQL, Sedona extends Spark and has embraced newer/faster file formats like GeoParquet. If you are familiar with Spark, using Sedona is probably...

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.

Night-time satellite imagery reveals a key reason for the Syrian Government's combat ineffectiveness.

Kyle Barron, Cloud Engineer at Development Seed. You’ve spent years figuring out how to visualize large geospatial datasets in web browsers. Can you tell us a bit about your background and what initially drew you to this area? I have a bit of a nontraditional background; I have virtually no official training in geography or computer science. In college, I was interested in urban and environmental economics, trying to understand how policies shape cities and the environment. I planned to pursue a PhD in economics and after college worked for a health economics professor at MIT for two years. In that time I learned data analysis skills, but more importantly, I learned that I preferred data analysis and coding to academic research. I decided not to pursue a PhD and left that job to hike the Pacific Crest Trail, a 2,650-mile hiking trail from Mexico to Canada through California, Oregon, and Washington. Over five months...

There’s a great discussion going on in the GeoParquet repo about how exactly to split up GeoParquet datasets for optimal querying. This post is my adventure giving the partition strategies a shot for practicality. All things are possible with enough software engineering effort, of course, but the ability to get these things done today on a bigger-than-memory dataset is what I’m after here. Notably, using DuckDB and Apache Sedona, since DuckDB can spill to disk when it runs out of memory and Apache Sedona can run on more than one computer if you need it to. In general, the partitioning has a few goals: Rows in each partition should contain features that are near each other. This maximizes the chance that fewer files with highly relevant content will be downloaded for a given search area. For a given search area, there should be as few possible files to download (i.e., partitions shouldn’t contain overlapping areas if possible). Each partition should contain approximately the same...

A little over a two years ago I wrote about point-in-polygon joins in R using an example of parking violations in Philedelphia. This example has been written about a few times involving a GPU example, using it as example for tuning PostGIS, a GeoPandas version for comparison, and a version comparing ArcPro, QGIS, PostGIS, and Manifold. I don’t want to downplay the parking example because it’s a realistic representation of problems on the larger end of the normal GIS realm. For many general-purpose data engineers, though, 9 million parking tickets is a drop in the bucket and the point-in-polygon counting might just be one step in a long pipeline of transformations. In particular, the problem has a crutial simplification: it fits comfortably in memory on just about any recent laptop. Let’s take the same problem up a notch but make it big enough that the naive approach will exhaust the memory of the average day-to-day laptop. By naive approach, I mean an approach that doesn’t involve any...

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

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