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.
