DESCRIPTION

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.

EXAMPLE

Set Celsius color table to monthly dataset 
t.rast.colors input=tempmean_monthly color=celsius

r.colors.out map=2009_01_tempmean
