Mapping our place in the world: The atlas for the 21st century. Worldmapper is a collection of world maps where countries are resized according to a broad range of global issues. Our cartograms are unique visualisations that show the world as you've never seen it before. Explore them all!
The underlying problem here is the database has the polygon for the building but not the exact point of the front door. So it guesses a point by filling in the centroid of the polygon. Which is kinda close but not close enough. A better heuristic may be “center of the polyline that faces the matching street”. That’s also going to be wrong sometimes, but less often.

Welcome to Native Land. This is a resource for North Americans (and others) to find out more about local indigenous territories and languages.
I ran across this over the Thanksgiving holiday. It would be cool to have more maps like this that spanned the globe as well as searchable by time span as well.Syndicated copies to:
In the early 1840s the American West, though claimed by the United States, was considered by many white Americans to be untamed, wild, and possibly rife with unknown wealth. This was a West that existed largely in the American imagination. In fact, the area west of the Missouri was home to complex Native societies, was divided into political structures, and was intimately known, if not formally mapped. These two competing Wests - that imagined by many Americans and that inhabited by Souix, Pawnee, Snake and Nez Pierce tribes - were mapped both geographically and textually by John C. Frémont between 1842 and 1843. Frémont set out from St. Louis in the summer of 1842, and began to chronicle his journey west, in the wake of "emigrants" who were moving to the Oregon Territory - a route known as the "Oregon Trail." Frémont's first expedition covered the land between the Missouri River and the Rocky Mountains during the summer and fall of 1842. In the summer of 1843 he set out to write an account of the second half of the Oregon Trail, from the Rocky Mountains to the Columbia River in Oregon. The maps contained here are drawn from the Library of Congress's collection "Topographical map of the road from Missouri to Oregon, commencing at the mouth of the Kansas in the Missouri River and ending at the mouth of the Walla-Wallah in the Columbia." They were created using Frémont's journal, and cover his first and second expeditions. I have annotated the maps with accounts of the resting places, flora, fauna, and people Frémont's and his party encountered on their journey west.
You’ve played the game Oregon Trail via DOS (as a child), online, or via app but have you traced the actual trail taken by John C. Frémont between 1842 and 1843? Now you can with this daily interactive map with journal.

An endless world map: Viewing the world through "Authagraph"
"Mr. Narukawa is the inventor of Authagraph, a world map designed to fit the world into a rectangle while almost perfectly maintaining the continents' relative size. It is mathematically impossible to precisely project the earth's sphere onto a rectangle. As such, previous methods would succeed in either taking on a rectangular shape or being true to the size ratio and shape of each continent, but never in both. Authagraph is groundbreaking in that it takes on both of those qualities, making it applicable to various themes such as sea routes, geology, meteorology and world history in ways never thought possible.
Instead of abstracting the globe into a cylinder, then a plane, as the more common Mercator projection map does, the AuthaGraph turns the Earth into a tetrahedron, which then unfolds in any number of ways. The map can then be tessellated similar to the way that we can traverse the planet–without ever coming to an end.
Rather than having just one focal point—the North Atlantic in Mercator’s case—nearly any place around the Earth can be at the center. The effect also means that the relative sizes of countries and their locations are much more representative than prior maps.
