t.rast3d.extract(1)

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

KEYWORDS
temporal, extract, raster3d, voxel, time

SYNOPSIS
t.rast3d.extract.py
t.rast3d.extract.py --help
t.rast3d.extract.py [-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.
