[GRASS-user] Color table for multiple rasters

GRASS GRASS user

I need to create a histogram equalized color table for a set of rasters. I can use r.colors for each raster individually but then the color tables are not comparable across the maps. Any suggestions on how to create a color table across multiple rasters?

Thanks,
Jitu

Maybe you’re looking for: r.colors map=$map rast=$other_map

You can give each map the color table from one particular map and then it will be comparable across maps. You’ll need to make sure you give it the color table from the map with the widest range though, or else you’ll have some spots in your map with no color.

Best,
Nick
