Note: This document is for an older version of GRASS GIS that will be discontinued soon. You should upgrade, and read the current manual page.

NAME

t.rast3d.algebra - Apply temporal and spatial operations on space time 3D raster datasets using temporal 3D raster algebra.

KEYWORDS

temporal, algebra, raster3d, voxel, time

SYNOPSIS

t.rast3d.algebra

t.rast3d.algebra --help

t.rast3d.algebra [-sng] expression=string basename=string [nprocs=integer] [--help] [--verbose] [--quiet] [--ui]

Flags:

-s: Check the spatial topology of temporally related maps and process only spatially related maps
-n: Register Null maps
-g: Use granularity sampling instead of the temporal topology approach
--help: Print usage summary
--verbose: Verbose module output
--quiet: Quiet module output
--ui: Force launching GUI dialog

Parameters:

expression=string [required]: Algebraic expression for temporal and spatial analysis of space time 3D raster datasets
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
