## NAME

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

## KEYWORDS

temporal, algebra, raster3d, voxel, time

## SYNOPSIS

t.rast3d.mapcalc.py
t.rast3d.mapcalc.py --help
t.rast3d.mapcalc.py [-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.
