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
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.
