t.rast.colors computes a color table based on all registered maps
of a space time raster dataset and to assign this color table to each map.
Hence the created color table reflects the data range of
the space time raster dataset. This module is a simple
wrapper around
r.colors.
All options of
r.colors are supported.
Internally a file with map names is created and passed
to the
file option of
r.colors.
Please have a look at the r.colors
manual page for further information.
Set Celsius color table to monthly dataset
t.rast.colors input=tempmean_monthly color=celsius
r.colors.out map=2009_01_tempmean
