Flags

-n

Register Null maps

-s

--overwrite

Allow output files to overwrite existing files

--help

Print usage summary

--verbose

Verbose module output

--quiet

Quiet module output

--ui

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
Options: 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

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.
