NAME

t.rast3d.mapcalc - Performs r3.mapcalc expressions on maps of sampled space time 3D raster datasets.

KEYWORDS

temporal, algebra, raster3d, voxel, time

SYNOPSIS

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,...] [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.
