Hi<br>I am using SRTM data for my study area with elevation values ranging from 12 m to 960 m. I have set the color table to bgyr. When I tried composing a map in ps.map using the above data with color table, it gave me the following error message:<br>
Your cats/ file is invalid. A cats/ file with categories and labels is required for 'colortable' when using CELL rasters. No colortable will be assigned to this output postscript file.<br>However, raster legend can be displayed in the grass map display window.<br>
I am using GRASS 6.3 on ubuntu 8.04<br>Can any of you advise me on how to overcome this problem and print color table?<br>Thanking you in advance<br><br>ramaraju<br>
