NAME

   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]   [suffix=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

   suffix=string
       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

   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.
