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.
