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.

Keywords

       temporal, algebra, raster3d, voxel, time

       --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,equaloutput=name[required]
           Name of the output space time raster3d dataset
