The result has the appearance of an old-fashioned, hand-drawn map.

Using image convolution and micro texture generation, it creates random paper textures on which it draws maps using randomly generated color schemes, and it uses words extracted from books to randomly create region, river, mountain, and city names. It uses a simple tectonic plate simulation to create islands and continents with trees, rivers, and mountains. Nortantis is a fantasy map generator originally created as an academic project.
