As I scrolled through Reddit I found one of the most interesting maps.

What started out as a "fun little geography mind game", which has been in the works for years now, has turned into a very interesting map.

The map showed the largest city in each 10-by-10 degree area of latitude-longitude in the world.

Well, guess what? Fort Collins was deemed the largest city in that 10-by-10 degree area of latitude-longitude

Hi everyone! Peter here from the Vexillographer geography YouTube channel, with an updated version of the "Largest City In Each 10-by-10 degree area of Latitude-Longitude in the World" map that blew up on r/MapPorn a few days ago.

This map has been in the works for a few years now, according to the Reddit user. "There were lots of unexpected surprises around the world about which cities and towns reign supreme in which squares."

Below you can see the original post on Reddit of the map.
