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


DESCRIPTION
       t.rast3d.algebra performs temporal and spatial map algebra operations on space time  3D  raster  datasets
       (STR3DS) by using the temporal 3D raster algebra.

   NOTES
       The module expects an expression as input parameter in the following form:

       "result = expression"

       The  statement  structure  is  exact  the  same  as  of  t.rast.algebra,  see  t.rast.algebra  but allows
       four-dimensional indexing.
