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

NOTES¶

"result = expression"

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