GRASS has a lot of nice pre-defined color tables. But one that is lacking is an SRTM-plus color table. This uses the SRTM color table for land, but has enough contrast to also show the sea floor. Currently, only ETOPO2 has a decent color table for the sea floor, but it is so light in shallow water that the land/sea boundary is not easily discernible if combined with the STRM land colors. So here is an attempt to find a combination of SRTM land, plus a pleasing sea floor color table. Maybe someone can improve on it more. In any case, I’d like to suggest that something along this line be incorporated into the stock pre-defined color tables in GRASS.
Cheers
Michael
