Performs r3.mapcalc expressions on maps of sampled space time 3D raster datasets.

Keywords

t.rast3d.mapcalc t.rast3d.mapcalc --help t.rast3d.mapcalc [-ns] inputs=name[,name,...] expression=string [method=name[,name,...]] output=name basename=string [nprocs=integer] [--overwrite] [--help] [--verbose] [--quiet] [--ui]

Flags

-n: Register Null maps
-s: Check the spatial topology of temporally related maps and process only spatially related 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

inputs=name[,name,...]Â [required]: Name of the input space time raster3d datasets
expression=stringÂ [required]: r3.mapcalc expression applied to each time step of the sampled data
method=name[,name,...]: The method to be used for sampling the input dataset
Options: start, during, overlap, contain, equal, follows, precedes
Default: during,overlap,contain,equal
output=nameÂ [required]: Name of the output space time raster3d dataset
basename=stringÂ [required]: Basename of the new generated output maps
A numerical suffix separated by an underscore will be attached to create a unique identifier
nprocs=integer: Number of r3.mapcalc processes to run in parallel
Default: 1

Description

t.rast3d.mapcalc provides exact the same functionality as t.rast.mapcalc, but for space time 3D raster datasets. Please refer to t.rast.mapcalc for documentation.

It is a simple wrapper for r3.mapcalc enhanced with temporal functions.
