The water map

The water map is a map of water levels and types. This structure, while large in memory, allow us to generate water bodies at different levels (ie. lakes) and non-flat water bodies such as rivers.

Here solid dark blue is sea, solid light blue are lakes, white pixels are water edges, and the spooky looking stuff is the water table (aqua around freshwater, green around sea water, deep blue when far underground).
