	GRASS GIS is one of the few GIS with volume data support. Here data are stored as a 3D raster with a unit volume called a voxel (volume pixel). [[Voxel]]s are designed to support for example representations of trivariate continuous fields.		GRASS GIS is one of the few GIS with volume data support. Here data are stored as a 3D raster with a unit volume called a voxel (volume pixel). [[Voxel]]s are designed to support for example representations of trivariate continuous fields. The latest version of GRASS7 supports space time voxel cubes that have time as the third dimension.
