openworld_radio_twin.providers.terrain.flat_terrain(query)[source]#

Return a gridded flat ground at local z=0 so surface classes can be assigned per cell.

No elevation source is queried. The grid uses the same axes as a DEM-backed terrain at the requested spacing, so semantic surface classification and the per-class terrain meshes work unchanged on a planar ground.

Return type:: TerrainGrid
