nprocs=integer
Number of r3.mapcalc processes to run in parallel
Default: 1
DESCRIPTION
t.rast3d.extract is used to extract a subset of a space time 3D raster dataset and to
store that subset in a different space time 3D raster dataset. It has exactly the same
functionality as t.rast.extract. The only difference is the that this module works on
STR3DS and 3D raster maps.
Please refer to t.rast.extract for documentation and examples.
