       t.rast3d.extract  - Extracts a subset of a space time 3D raster dataset.

KEYWORDS

       temporal, extract, raster3d, voxel, time

SYNOPSIS

       t.rast3d.extract
       t.rast3d.extract --help
       t.rast3d.extract  [-n]  input=name   [where=sql_query]    [expression=string]  output=name
       [basename=string]   [nprocs=integer]    [--overwrite]   [--help]   [--verbose]   [--quiet]
       [--ui]

   Flags:
       -n
           Register Null maps

       --overwrite
           Allow output files to overwrite existing files

       --help
           Print usage summary

       --verbose
           Verbose module output

       --quiet
           Quiet module output

       --ui
           Force launching GUI dialog

   Parameters:
       input=name [required]
           Name of the input space time raster3d dataset

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

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

       output=name [required]
           Name of the output space time raster3d dataset

       basename=string
           Basename of the new generated 3D raster maps

       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.
