The land of Ooo is the central setting of the series Adventure Time. As a big fan of this series, I have designed the world map once in a very detailed terrain model. This is not 100% accurate and has some differences in places, which is due to erosion, However, it largely follows the map given by the series and gives a possible look at Ooo, as it might look in a non-cartoon world.
The world map published by Cartoon Network, which can be found on the Adventure Time Fandom Wiki page, was used as a reference for the creation of the world map. Based on this map, a shape of the island was created and then converted into a height map using GAEA. Various process steps like noise, erosion and sedimentation were used to make the look of the island as authentic as possible.
Due to this physically simulated erosion, some parts of the island are „sunken in the sea“ and differ from the original reference.
