Name of the input space time raster3d dataset

WHERE conditions of SQL statement without ’where’ keyword used in the temporal GIS framework
Example: start_time > ’2001-01-01 12:30:00’

The r3.mapcalc expression assigned to all extracted 3D raster maps

Name of the output space time raster3d dataset

Basename of the new generated 3D raster maps

Suffix to add at basename: set ’gran’ for granularity, ’time’ for the full time format, ’num’ for numerical suffix with a specific number of digits (default %05)
Default: gran

Number of r3.mapcalc processes to run in parallel
Default: 1


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.
