TorchGeo: v0.9.0

TorchGeo: v0.9.0

TorchGeo 0.9.0 Release Notes

TorchGeo 0.9 includes 13 new datasets and a number of improvements required for better time series support, encompassing 3 months of hard work by 15 contributors from around the world. We are now trying to make more frequent releases to get exciting new features out to users as quickly as possible!

Highlights of this release Embeddings datasets

TorchGeo was the first library to provide pre-trained geospatial foundation models, and offers more GeoFMs than all other GeoML libraries combined [1]. Users have always had the ability to generate their own embeddings using TorchGeo. However, using FMs requires considerable expertise and compute, preventing widespread adoption.

Mapping the Hollowing of the United States

Mapping the Hollowing of the United States

The American population is moving south and west. You can see that migration writ large in the US Population Growth Atlas, an interactive map showing how the populations of every US county and state have changed between 1980 and 2025.

The most striking feature of the map is the broad band of population decline running through the middle of the country. From the Dakotas and Montana, south through Nebraska, Kansas and Oklahoma and into parts of West Texas, large numbers of counties are coloured red or orange. It is an “Emptying Middle” separating the rapidly growing populations of the coasts and the Sun Belt.

GIScussions: Mapping Maps in the Wild – a complex collaborative project

GIScussions: Mapping Maps in the Wild – a complex collaborative project

Maps in the Wild

Mappery has been my side project for 8 years, for the last 5 or 6 years Arnaud Ferrand has been my co-editor and the tech brain that keeps the site running. Mappery is a large WordPress site with 2,500 posts and 3,500 images of Maps in the Wild (pictures of maps in the street, on clothes, furniture, alcohol etc).

For several years we had a map plugin that allowed us to enter a coordinate pair for a post and to render a clustered map with pins representing each post, click on a pin and the post image and some text appears in the popup with a link to the post. It worked ok but the map used the Google Maps API which had cost implications and we also had several complications with the map not rendering and the plugin wasn’t being maintained.

7 Billion People Are Awake Right Now

7 Billion People Are Awake Right Now

At the moment (as I write), 6.962 billion people are awake, while another 2.1 billion are fast asleep. Awake Globe visualizes this constantly shifting global rhythm of sleep and wakefulness, revealing where people around the world are currently awake, asleep, or somewhere in between.

The map presents the Earth as a glowing, rotating globe. Daylight sweeps across its surface at around 1,000 miles per hour (at the equator), while millions of tiny coloured points show where people are currently awake or asleep. Blue represents people who are tucked up in bed, while green indicates those who are awake, with a spectrum of colours in between showing the gradual transition from sleep to wakefulness.

CastleGuessr

CastleGuessr

I had determined not to post about Castle Map despite it being written about extensively elsewhere. There are already hundreds of maps of castles around the world and, although I have nothing against AI-generated maps, this one struck me as particularly uninteresting.

That first impression wasn't helped by the site's design. Castle Map takes the illegible grey-text-on-a-black-background AI design trend to even greater lengths by applying the same colour scheme to the map itself, with dark grey land set against a black sea. Not only are the menu options in the legend almost impossible to read, but the map itself is barely legible.

However, today I discovered that Castle Map includes a neat GeoGuessr-style game: CastleGuessr

Ecodiv.earth: m.printmap, a new addon to create maps in GRASS

Ecodiv.earth: m.printmap, a new addon to create maps in GRASS

For reports, presentations, and websites, I regularly need maps: a raster layer, contextual boundaries, a legend, and maybe a logo. Nothing requiring an elaborate page layout. And I often need more than one. For the COMBINED project, for example, I map the same study area in Rotterdam over and over. The extent, the boundaries, and the logo stay put; only the raster and its legend change. Exactly the kind of repetition worth automating.

A World of Plane Crashes

A World of Plane Crashes

If you are already afraid of flying then you might want to give CrashAtlas a miss. This interactive map of aircraft accidents is unlikely to do much for your aerophobia. On the other hand, if you've ever wondered whether a plane has crashed near your home, then CrashAtlas may prove to be a fascinating, if slightly macabre, diversion.

CrashAtlas is a global interactive map dedicated to documenting the history of aviation accidents and incidents around the world. The map plots thousands of crash locations, allowing you to explore where aviation accidents have occurred geographically.

Isometric San Francisco

Isometric San Francisco

Following the success of Isometric NYC, it was probably only a matter of time before another city received the same pixel-art treatment. Now Isopolis - San Francisco has recreated the City by the Bay as a sprawling isometric world that looks as though it has been lifted straight from the golden age of SimCity.

From the skyscrapers of the Financial District to the city's famous hills, bridges and waterfront, San Francisco has been transformed into a giant retro cityscape that invites endless exploration. SimCity fans will immediately recognize the aesthetic. The map captures San Francisco as a dense tapestry of tiny buildings, winding streets, parks and piers, all rendered in a consistent pixel-art style.

Don't Miss the Eclipse!

Don't Miss the Eclipse!

On August 12, 2026, a total solar eclipse will cross Greenland, Iceland and northern Spain. While eclipse chasers in Spain can enjoy totality, there is one potential problem. By the time the Moon's shadow reaches the Iberian Peninsula, the Sun will be hanging just above the western horizon. If there's a mountain between you and the setting Sun, you could miss part - or even all - of the eclipse.

Alessio Zanol's EclipseMap is designed to solve exactly that problem. Rather than simply showing the path of totality, the interactive map calculates how the surrounding landscape affects your view of the eclipse, helping you find locations where the horizon remains clear.

The Map of Global Friendship

The Map of Global Friendship

Social Connectedness Index Map
St. Louis, Missouri and Bosnia and Herzegovina are separated by more than 5,000 miles. Yet Facebook friendship data reveals that the two places share remarkably strong social ties. An unusually large number of people in St. Louis have Facebook friends in Bosnia and Herzegovina.
The explanation lies in the Bosnian War of the 1990s. Tens of thousands of Bosnian refugees settled in St. Louis, creating the largest Bosnian community per capita outside Europe. Decades later, those family relationships, friendships and community networks remain so strong that they stand out as one of the most striking patterns in Meta's global dataset of social connections.
The Social Connectedness Index (SCI), developed by Meta's Data for Good team, was designed to measure these otherwi...

Mapping Meals Under $10

CheapFoodMap is an interactive map that highlights restaurants across the United States where you can still find meals for under $10. Rather than focusing on national chains, it celebrates local diners, neighborhood taquerias, family-owned cafés and other hidden gems.

Every listing includes the featured meal, its current price and the date that the price was last verified, allowing users to judge how reliable the information is in an age of inflation, when menu prices seem to change every few months.

German Döner, English Curry & American Pizza

German Döner, English Curry & American Pizza

German Döner Kebab restaurants have started popping up all over London. For some reason, the idea of a German kebab still strikes me as slightly incongruous - a bit like a Swiss curry or a French taco. However, according to a recent analysis of OpenStreetMap food venues, there are far more döner kebab restaurants in Germany than there are in Turkey. In fact, 51% of the world's döner shops are located in Germany.

The surprising truth is that restaurant names often tell us more about migration and language than they do about the birthplace of a dish. That's the premise behind Flavor Lines, an ingenious interactive map that uses millions of restaurant names from OpenStreetMap to reveal the invisible cultural boundaries that shape the world's cuisine.

Bigfoot's Giant Step Forward for Tourism Maps

Bigfoot's Giant Step Forward for Tourism Maps

Tourism websites often present destinations using static maps, brochures and carefully curated lists of attractions. Bigfoot's BC demonstrates that there is a much more engaging alternative. By turning British Columbia into a playful 3D world that visitors can explore as a giant Sasquatch, it transforms the traditional tourist guide into an interactive adventure.

Built with three.js and powered by open geographic data, this map recreates the province of British Columbia as a charming low-poly landscape. The terrain follows British Columbia's real topography, while roads, lakes, parks and settlements are all positioned using real-world geographic data. The result is a map that resembles an open-world video game.

The Many Maps of the Odyssey

The Many Maps of the Odyssey

Since the launch of the Google Maps API back in 2005, two fictional journeys have been mapped over and over again: Phileas Fogg’s global circumnavigation in Around the World in Eighty Days, and Odysseus’ long voyage home in the Odyssey.

For some reason Homer’s hero is having a bit of a moment - and a sudden surge of new Odyssey maps means Odysseus seems to have pulled ahead of Phileas Fogg in the fictional journey mapping contest.

Can You Date the Map? - Daily Challenge


Randall Munroe's famous xkcd comic Map Age Guide distilled two centuries of global geopolitics into a wonderfully simple flowchart for dating maps. Does the map show Germany divided into East and West? Is there a Yugoslavia? Does South Sudan exist? By answering a handful of such questions about borders and country names, the comic demonstrates how you can usually work out when almost any modern map was made.

How Close is Everything You Need?

How Close is Everything You Need?

One of the biggest challenges when moving home is deciding which compromise you are prepared to make. You might want to live close to work, a good school, a supermarket, a park, a gym and your favourite coffee shop - but finding somewhere that sits within easy reach of everything is rarely possible.

Close is an interactive travel-time map of the United States designed to solve exactly that problem. Instead of measuring access to just one destination, it allows you to select up to six different amenities and then colours every census block according to the travel time to the furthest of those destinations.

Using Close is refreshingly straightforward: 

  1. Search for a city or neighbourhood
  2. Add the destinations that matter to you
  3. Choose how you would travel to each one - walking, cycling or public transport

OSGeo Announcements: [OSGeo-Announce] OSGeo establishes a European legal foundation

Wageningen, The Netherlands, 21 July 2026.

The Open Source Geospatial Foundation (OSGeo) has established a legal foundation in Europe. The founding documents were signed yesterday. The new entity, Stichting Open Source Geospatial, has its statutory seat in Wageningen and operates under the OSGeo name and mission. It gives the foundation a legal presence in the European Union alongside its existing entity in the United States.

The step fits a wider move toward digital sovereignty. Governments and organisations across Europe want control over the software and data they depend on, and open-source geospatial technology gives them that control. A European foundation lets OSGeo take part in that shift as a recognised local partner, and gives the people and companies who build OSGeo projects a stronger voice in it, along with better business opportunities that follow from working close to European institutions and funding.

The 5 Best 3D Subway Maps

The 5 Best 3D Subway Maps

Shinjuku Station has a well-earned reputation as one of the world's largest and most bewildering transport hubs. The  Shinjuku Station Indoor interactive 3D map tackles that complexity by turning the station's official indoor mapping data into a clean, schematic three-dimensional blueprint. This map strips everything back to the essential geometry of corridors, platforms and rooms, making it much easier to understand how the station's many levels fit together.

Navigation is simple and intuitive. Users can pan across the station, zoom in and out, and hold Ctrl while dragging the mouse to rotate the view, making it easy to examine the station from almost any angle. Individual floors can be toggled on and off using the built-in control panel, allowing users to isolate a single level or view multiple floors stacked vertically.

Street Names - As Ranked by the Internet

Streetnames by Elo is a fascinating interactive map which colours streets according to how highly the internet rates the people, places or things they are named after. The map combines OpenStreetMap's `name:etymology:wikidata` tags with EloEverything's crowd-sourced Elo rankings to create a surprisingly revealing view of the world's street names.

EloEverything asks users to choose which of two randomly selected things they prefer, building an Elo rating for everything from the Sun to headaches. By matching those ratings to OpenStreetMap's street etymology data, Streetnames by Elo turns road networks into a colour-coded map of collective internet opinion.

The Global Map of Agricultural Decline

The Global Map of Agricultural Decline

This animated map reveals how agricultural productivity is expected to be affected by climate change around the world throughout this century. It uses the new Climate-Driven Agricultural Decline Index (CADI) to show where and how global heating is likely to alter crop-growing conditions.

According to the Climate-Driven Agricultural Decline Index, more than 640 million people already live in agricultural regions where food production has fallen by over 10% compared with 30 years ago. Looking ahead, the map suggests these declines will accelerate, with almost half of the world's population expected to be living in areas experiencing reduced agricultural productivity by the middle of the century under a high-emissions scenario.

Kartoza: How to Use Custom Icons in Maputnik (Sprite Sheet Guide)

The Missing SVG Button

If you have ever tried styling a vector map in Maputnik, you have probably hit this wall: you have a folder full of perfectly designed SVG icons, but there is no simple “Upload SVG” button for your symbol layers.

Unlike desktop GIS software, web mapping specifications (like MapLibre and Mapbox GL) are optimised for rendering speed. Loading hundreds of individual SVG files requires too many HTTP requests and bogs down performance. Instead, the style specification requires a sprite sheet : a single raster image (PNG) containing all your icons, paired with an index file (JSON) that tells the map exactly where each icon sits on that image.

Where's Downtown?

Where's Downtown?

Where is Downtown? is an interactive map surveying tool designed to crowdsource the boundaries of "downtown" for any city. 

The process is very simple:

  • Enter the name of a city into the search bar
  • Draw your perceived outline of "downtown" on the map
  • View a heatmap of all the collective responses submitted so far

If you are only interested in exploring where others think downtown is, you can skip the drawing stage entirely and head straight to the crowdsourced results for your chosen city.
On these crowdsourced maps, a heat-map color scale highlights the areas most frequently identified as downtown. You can also hover your cursor over any location on the map to see the exact percentage of users who included it in their "downtown" boundaries.

Launched in late 2025, Prakrit Ojha's War Atlas is an interactive map that visualizes more than 8,500 historical battles. Spanning from 1500 BC to the present day, it offers an immersive, guided tour through the history of human conflict.

Now there’s another War Atlas on the scene. Not only does this new map share the same name, a very similar URL, and a nearly identical thematic DNA, it also adopts a very similar AI-generated aesthetic. (A quick plea to all vibe-coders out there: please stop with the microscopic gray text on black backgrounds!) 

While the original War Atlas focuses on the precise points where battles took place, this new version tackles the broader political canvas. It maps 10,584 named conflicts layered over fluid, shifting empire borders spanning from 2500 BCE to the present day.

GIScussions: Backdating the Defence Map to the End of the Cold War – Claude Understands UI Better Than Me

GIScussions: Backdating the Defence Map to the End of the Cold War – Claude Understands UI Better Than Me

After I published my map of defence spending a friend suggested that it would be interesting to see how things had changed since the end of the Cold War in 1990/91.

I knew that the data I had covered a longer time period so I asked Claude if we could update the map and it checked the data and confirmed that there was reasonable data coverage back to the mid 70’s so I decided to backdate (or is it update?) the map to run from 1975 to 2024.

What’s new

The extended map now runs from 1975 to 2024, covering periods that include the final years of the Cold War, the collapse of the Soviet Union, the post-9/11 surge in Western defence spending, and the sharp remilitarisation following Russia’s invasion of Ukraine.

Sean Gillies: Run Rabbit Run training weeks two through seven

Sean Gillies: Run Rabbit Run training weeks two through seven

The first half of summer has flown by. I'm quickly catching up on six busy weeks here.

  • 53 hours, 52 minutes all training

  • 130.1 miles running and hiking

  • 16,220 feet D+ running and hiking

That's about 9 hours of exercise, 22 miles of running and hiking, and 2,700 feet D+ per week. I've been active enough to maintain my base fitness, but haven't done much building. Travel and vacation have kept me from sticking to a regular workout schedule.

In week two, I participated in Laramie's Pilot Hill Classic 25K race for the first time. I experienced cramps again, but not as bad as at Quad Rock. I tripped a few times on the way down, and once did a full Superman dive, head-first, onto a smooth (luckily) stretch of trail. I had some calf cramps and a bloody elbow after that, but the cramps cleared up before the finish.

Green plains and hills under a partly cloudy sky at dawn.

Mapping the Origin of Life, the Universe, and Everything

According to Haudenosaunee tradition, the Earth was once entirely covered by water. One day a muskrat swam to the bottom of the great sea and surfaced with a tiny clump of mud. This mud was placed on the back of a giant turtle, where it grew until it became the earth.This is just one of dozens of creation stories that you can explore on the Origin Myth Map, an interactive atlas of the myths that

GIScussions: Who Spends the Most on Defence and Who’s Selling the Weapons?

GIScussions: Who Spends the Most on Defence and Who’s Selling the Weapons?

With Keir Starmer recently losing a Defence Secretary and then leaving a budgetary timebomb for his successor as PM, Andy Burnham, I thought it might be interesting to see how we rank on defence spending and who are the world’s largest exporters and importers of arms.

I started out by trying to find some data on arm sales and Claude sent me to SIPRI where you can download very granular data on almost every transaction but after playing with the data I decided to take a simpler approach and map expenditure as a % of GDP (which is what Trump and the NATO powers have been arguing about) and exports and imports of major arms.

Geographical Overlords

This morning I listened to the song Geographical Overlord by MastaMic and Titus Chan.

gvSIG Team: Curso de manejo básico de la Suite gvSIG (Desktop, Online y Mapps) aplicado a la gestión municipal: Vídeo 3 – Tablas de atributos y selecciones en gvSIG Desktop

En el vídeo anterior cargamos capas y trabajamos su representación visual. En este tercero vamos a lo que hay “detrás” de la geometría: la tabla de atributos. Cualquier capa en un SIG lleva asociada una tabla con los datos descriptivos de cada elemento, y aprender a moverse con soltura entre mapa y tabla es uno de los hábitos más útiles del trabajo diario.

Partimos de un proyecto con tres capas centradas en un caso muy habitual en la gestión municipal, la organización electoral: mesas electorales (puntos), ejes de carreteras (líneas) y distritos electorales (polígonos). De paso nos sirve para repasar los tres tipos de geometría con los que vamos a trabajar a lo largo del curso. Sobre los distritos aplicamos una simbología por valores únicos, esta vez clasificando por un campo de la propia tabla.

Nick Bearman: Introducing: gitRmap / “Guitar Map”

Nick Bearman: Introducing: gitRmap / “Guitar Map”

I’d like to introduce gitRmap: a semi-automated map of locations that you can add your own points to. It’s designed for people who are new to GIS, but who know a little bit of Git.

You can create a map like the one below, with your own pins on it, just by following the quick start at nickbearman.com/gitRmap.

If you get stuck, I want to know! Message me, email me or open an issue on GitHub.

What is gitRmap?

I wanted to create a tool that made it easier for more people to make maps. There are plenty of tools out there for creating a web map, but for someone new to GIS they can be pretty intimidating.

QField: The many ways to share maps with friends, teammates, and the public in QField

Over the years, QField has gained a number of ways through which authors can share their mapping projects. This post looks at the multiple ways this can be achieved and what scenarios fit each method best.

Leveraging QFieldCloud Sharing maps to the public

QFieldCloud users all have the ability to configure their projects as ‘public’. When the option is turned on, all QFieldCloud users will be allowed to download and browse these maps at will.

These users coming in to view the map are given a reader role, prohibiting changes to the underlying datasets included in the project. This can be a great option when wanting to share maps to a large number of readers while relying on QFieldCloud to host the content and keep users up-to-date through synchronization.
