The CFB Charts Imperialism Map is a fan-created, season-long project that turns the college football season into a map-based "conquest" game. It started on Reddit and Twitter a few years ago and has become a tradition among college football fans.Here’s how it works (I think):Each FBS team begins the season owning the county in which its school is located (and probably all the nearest counties).

Ley Line Locator
The idea of ley lines was first proposed in the 1920s by the amateur archaeologist Alfred Watkins. In his book, 'The Old Straight Track', Watkins suggested that many ancient sites in Britain - such as standing stones, barrows, and old churches - could be joined by drawing straight lines across the landscape. He believed these alignments were not accidental but reflected a

The map's primary purpose is to highlight the dramatic difference migration makes to Europe's population projections by 2100. It successfully achieves this by comparing Europe's projected population "With migration" and "Without migration".It is often

Meteorological fall started on September 1, but if you live in the contiguous U.S., you may not have noticed the typical crisp, cool air. That's because the season has been steadily warming for decades. Since 1970, average fall temperatures have risen in every single county in the country.On average, fall temperatures are now a remarkable 2.8°F warmer than they were in the early 1970s. This

Last week someone posted an animation of a Typographic Map of France on Reddit. This map gradually added the names of 1,156 French communes to a blank canvas, starting with those with the largest populations. I really liked the effect of the animation and remembered that TripGeo's Scrambled Maps has a database of around 11,000 cities worldwide - complete with population data.

Dot maps can be a powerful way to convey the scale of large numbers. But when each dot represents a human life, there’s a risk that the individual stories behind those numbers will be lost. Reuters’ latest visualization of European migration tackles this challenge head-on: instead of starting with statistics, it begins with a close-up of a single overcrowded boat, allowing viewers to see the

In 2024, atmospheric methane levels reached their highest point in more than 800,000 years, with the oil and gas sector playing a major role in that surge. The methane leaks from oil and gas operations don’t just warm the planet - they also release toxic pollutants that can harm people’s health.The Methane Risk Map plots significant methane leak events across the United States.

The geo-guessing genre has seen a sudden surge in AI-powered experimentation. Just yesterday, I reviewed GeoGPT, which pits players against an AI to identify locations using Mapillary imagery.

GeoGPT is now one of my favorite geo-guessing games. GeoGPT follows the usual GeoGuessr inspired format: you’re dropped into a random street-level image, and your task is to figure out where in the world you are. But here’s the twist - rather than competing against other humans, you’re up against an AI, which makes its own guesses alongside yours. The closest guess to the true location wins

One of my favorite recent side-projects has been Meet Cute, a playful web map that generates tiny “micro-romance” stories whenever you click on a location. The conceit is simple: click on a map, and out comes a love story set in the nearest town.
But behind that simple experience was a not-so-romantic technical problem: finding the name of the nearest town.
At first, I leaned on the Overpass API
