2. French Guiana is legally part of France, and not a separate country, in a similar way to Hawaii being legally part of the USA. Technically all maps of France should probably have a window with French Guiana in the corner, the way Hawaii usually appears on maps of the USA.
3. There is a fictional island in the South Atlantic, off the west coast of Africa called 'Null Island.' Although it doesn't exist in reality, it serves as an error trap for map systems. Map enthusiasts have given the island its own history, geography, and even a flag.
4. The township of Northwest Angle in Minnesota was a geographic oddity caused by surveying errors, and is affectionately known as the Angle. It was created when map maker, John Mitchell miscalculated the source of the Mississippi being the ‘Lake of The Woods.’ The Northwest Angle's only land link is its western border with Manitoba. It's technically part of Minnesota, but with Lake of the Woods to the south, it shares no land connection with the United States. Its residents have to pass through the Canadian border twice to get to mainland US.

7. Canada, Russia, and Greenland aren't nearly as big as most of us think. Most of us have learned world geography from a Mercator map, which distorts the true size of certain countries because it depicts a 3D sphere as a 2D rectangle.
8. The world's shortest mountain, Mt. Tenpo, is 20 m tall. It's only a mountain because it was described as one on a topographical map put out by the Geographical Survey Institute of Japan. You can even get a certificate for summitting the mountain at a nearby cafe.

The naming of the North & South America continent in honor of Amerigo Vespucci was the result of a mistake by a German cartographer while making a map of the world in 1507 who thought Vespucci rather than Columbus was the explorer who discovered America after reading a document called Mundus Novus.
10. To pep up the look of a bland 70s Chicago office building, a design firm 2013 added a 400-foot-tall map of the city. The modernistic 35-story map is all gray and black except for the representation of the host building (300 S Wacker Drive) which is shown in red and lights up at night.

14. A fitness tracking app unknowingly revealed locations of secret US army bases. When the app released a map with over 3 million data points, it showed popular running routes. Data shared by soldiers on the app was detailed enough to reveal sensitive information of users on active military service.

22. French King Louis XIV commissioned the creations of "Plans-reliefs," which were 3D maps of towns, landscapes, and fortresses for planning military actions, starting in 1688. Hundreds were produced up until 1870 and many examples survive to this day in several museums in Paris.
