t.rast3d.mapcalc
Performs r3.mapcalc expressions on maps of sampled space time 3D raster datasets.
t.rast3d.mapcalc [-ns] inputs=name [,name,...] expression=string [method=name [,name,...]] output=name basename=string [nprocs=integer] [--overwrite] [--verbose] [--quiet] [--qq] [--ui]
Example:
t.rast3d.mapcalc inputs=name expression=string output=name basename=string
grass.script.run_command("t.rast3d.mapcalc", inputs, expression, method="during,overlap,contain,equal", output, basename, nprocs=1, flags=None, overwrite=False, verbose=False, quiet=False, superquiet=False)
Example:
gs.run_command("t.rast3d.mapcalc", inputs="name", expression="string", output="name", basename="string")
Parameters
inputs=name [,name,...] [required]
Name of the input space time raster3d datasets
expression=string [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
Allowed values: start, during, overlap, contain, equal, follows, precedes
Default: during,overlap,contain,equal
output=name [required]
Name of the output space time raster3d dataset
basename=string [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
-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
--qq
Very quiet module output
--ui
Force launching GUI dialog

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.
