A semantic terrain engine
summary
terra.js is a WebGL terrain engine that consumes land cover data, elevation (SRTM) and satellite imagery, tiles them with level‑of‑detail and streams only needed tiles. a GPU vertex shader displaces a flat mesh into terrain and a fragment shader selects water/forest/sand shaders from the semantic map and blends satellite color. prototypes render the Czech Republic and a realtime train overlay built in a couple weeks; planned features include procedural cities and algorithmic botany.
