KEYWORDS

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