Only available in Development branch(es) until its release with Arma 3 patch v2.10.

Description:: Returns the terrain heightmap information, as well as sea level offset (due to tides, if available).
Groups:: Diagnostic

Syntax:

getTerrainInfo

Return Value:

Array - In format [landGridWidth, landGridSize, terrainGridWidth, terrainGridSize, seaLevel]:

landGridWidth: Number - width of each land grid
landGridSize: Number - number of land grid pixels
terrainGridWidth: Number width of each terrain grid (also known as "cell size")
terrainGridSize: Number - number of terrain grid pixels (also known as "heightmap resolution")
seaLevel: Number - sea level without waves. The value is 0 if tides are disabled.

ⓘ

The result of landGridWidth * landGridSize and terrainGridWidth * terrainGridSize is always equal to the worldSize.
"land grid" is used by the game for object placement (e.g. finding the nearestObject), dynamic simulation, etc.
"terrain grid" is used for showing the terrain, measuring surface normal, etc.
