## DESCRIPTION

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

### NOTES

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.
