What is a TERRAIN file

TERRAIN files mostly belong to Terrain Editor. TERRAIN files hold game terrain data used in video games. They store map details and ground features that the game engine reads for building game levels.

The file format may use GZIP compression to reduce size and speed up data loading.

The data includes layout, height maps, and collision information needed by the game.

One variant is used by Valve projects for game map data and another by Jurassic World Evolution 2 to store terrain specifics.
