Where does the North Begin?

Where does the North Begin?

One of the perennial questions in UK politics and geography is “where is the border between the North and South?” I can now definitively answer that question thanks to MapSplit.

Giuseppe Sollazzo’s MapSplit interactive map allows you to map any UK-specific dataset and then “draw a movable straight line across the UK” to view a statistic for each side. This means I was able to upload all the Greggs outlets in the UK onto Giuseppe's map and instantly discover the dividing line across the country where there are an equal number of Greggs north and south of the line. Ending, forever, the debate about the border between the North and South.

Kartoza: Kartoza's QGIS Plugins: Extending QGIS for Real-World GIS Workflows

QGIS is powerful out of the box, but its real superpower is extensibility. For over a decade, Kartoza has been building, sponsoring, and maintaining QGIS plugins that solve genuine geospatial problems — from cadastral surveying in South Africa to monitoring land degradation for the United Nations Sustainable Development Goals. This post is a quick tour of the plugins we ship, where to find them, and how they fit into a modern open source GIS workflow.

How to Find the Best Sunset Views

How to Find the Best Sunset Views

If you want to discover the best spots nearby to watch the sunset, then you need the Sunset Atlas. Choosing a good local spot to watch the sun disappear below the horizon can involve a fair amount of trial and error. Sunset Atlas takes some of the guesswork out of finding the perfect sunset viewpoint by mapping sunset viewing conditions across Europe.

The interactive map uses a colourful heatmap to show the quality of sunset views, with warmer colours indicating locations where the setting sun has a more unobstructed line of sight. You can click on the map to see the Sunset Score for any location, rated from 0 to 100. Or click on the 'Find Best Spots' button to instantly discover the highest-scoring sunset spots near your location.

Trains and Termini

tokyo-trains

It is a truth universally acknowledged, that a city in possession of a good railway network, must be in want of an animated train map. Yet, having once beheld the grandeur of Mini Tokyo 3D and the intricate labyrinth of the Shinjuku Station Indoor, one might reasonably despair of any further elegance in the art.

Mr. Gregg Tavares, however, was of a different mind entirely. Reader, he married them.

Sandro Santilli: Suspended from FLOSS.social for Using LLMs

My account on FLOSS.social, @strk, has been suspended. Not for writing toots with an LLM, but for writing toots about LLMs - mostly. One of the thirteen cited toots was not mine at all: it was my boost of a toot written by my AI minion. This is how it happened, and why I think the whole thing stinks.

The Freeze

On July 27, 2026 I received an email from admin@floss.social with subject “Your account @strk@floss.social has been frozen”. It said my behavior was “found to be in violation of our FLOSS.social Community Code of Conduct” and cited thirteen of my toots. All of them were about LLMs and AI coding agents. Examples:

@cm@chaos.social using LLM is too fun to stop. Scratching your own itch is just a matter of asking your computer to do it.

Finding the Falcon 9 Crash Site on the Moon

Finding the Falcon 9 Crash Site on the Moon

Last week Elon Musk's SpaceX Falcon 9 rocket crashed into the Moon. You can view its estimated impact site on azmth Luna, an interactive 3D map of our nearest neighbour. Enter “Falcon 9” into the map's search box and the crash site is highlighted on the lunar surface, near the Einstein crater on the Moon's western limb.

The Falcon 9 crash is just one of 44 landing and impact sites mapped by azmth Luna. These range from the Soviet Union's Luna 2 in 1959 to the latest commercial lunar missions, with successful landings, failed missions and accidental impacts all represented. The resulting collection provides a comprehensive visual history of humanity's attempts to reach the Moon.

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

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

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.

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...

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.

The Odyssey Journey

The latest entry in this sudden wave of Homeric cartography is The Odyssey Journey, an animated, narrated retelling of Odysseus' decade-long voyage back to Ithaca.

Free Map Tiles for Everyone

Free Map Tiles for Everyone

Free Map Tiles Providers:

One of the biggest barriers to building web maps has always been the cost and complexity of map tiles. Services such as Google Maps and Mapbox offer excellent infrastructure, but commercial pricing can quickly become prohibitive as projects grow. Self-hosting OpenStreetMap vector tiles is an alternative, but maintaining a global tile server yourself is far from trivial.

Can You Date the Map? - Daily Challenge

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.

Date the Globe turns this idea into a really fun daily map game.

Benjamin BĂŒrbaumer, 2024, Chine/États-Unis, Le capitalisme contre la mondialisation, Paris, La DĂ©couverte, 304 p.

La politique interventionniste des États-Unis, au mĂ©pris du droit international, ne manque pas de faire pleuvoir nombre de commentaires en ce dĂ©but d’annĂ©e 2026. Quand certains, sidĂ©rĂ©s – à juste titre – par l’enlĂšvement du prĂ©sident vĂ©nĂ©zuĂ©lien NicolĂĄs Maduro ou par les bombardements en Iran, y voient l’Ɠuvre d’un fou agissant de maniĂšre impulsive, d’autres, adoptant une lecture matĂ©rialiste des faits, font valoir des enjeux plus profonds. Le discours mĂ©diatique parle dĂ©sormais de dĂ©dollarisation, de corridors terrestres, du dĂ©troit d’Ormuz, de pipelines, du pĂ©trole vĂ©nĂ©zuĂ©lien et des hydrocarbures russes, mais surtout de la Chine, puissance miroir des États-Unis, Ă  chaque fois impactĂ©e, si ce n’est indirectement ciblĂ©e.

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.

GRASS GIS: GRASS Community Meeting 2026 Report

The GRASS Community Meeting 2026 was held at Fondazione Edmund Mach (FEM) in San Michele all’Adige, Trentino, Italy, from July 11 to 19. The event brought together users, supporters, contributors, power users and developers from around the world for a week of focused, in-person collaboration. As is tradition for these meetings, a large part of the week went into maintenance that simply doesn’t happen at the same pace when the team is scattered across time zones: reviewing, testing, and merging or closing pull requests and issues, following up on stale discussions, and cleaning up long-standing rough edges across the GRASS repositories.

Street Names - As Ranked by the Internet

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.

Depuis 1967, les axes routiers des territoires occupĂ©s sont contrĂŽlĂ©s par IsraĂ«l. Le rĂ©seau de « checkpoints » et d'entraves Ă  la circulation, illĂ©gal au regard du droit international, s'est considĂ©rablement dĂ©veloppĂ© au dĂ©but des annĂ©es 1990. Ces postes militaires assurent le maillage des territoires palestiniens, fractionnĂ©s par l'enchevĂȘtrement de colonies et le mur de sĂ©paration. Selon les Nations unies, une centaine de « checkpoints » sont rĂ©partis Ă  travers la Cisjordanie, sans compter les quelque quatre cents obstacles matĂ©riels – barriĂšres, blocs de bĂ©ton, monticules de terre

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)

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.
