I am trying to create a single color map to overlay the elevation map to show the different elevations. I clicked on properties of my raster map and was able to create the color map by choosing psudocolors but I do not have any luck when I pick custom color map. Does anyone have any suggestions?

I have a raster map with all categories (~50)
and I have about 500 spatial subsets of the same
original map. As is expected, each of spatial subset
map have less categories than the original map.I can check the list of categories for each subset
map using r.stats. But I need to generate a new
set of maps with the spatial range of original map,
but keeping only those classes of my original map.Just supose that “r.stats mysubset1” result something
like:2
4
9
11
43So, I would like that my new map with my full spatial
range keep only these 5 categories, and all other
categories come to be “no data”.I know if I generate a rule file with
2=2
4=9
11=11
43=43
I can get the desired results, but as the number
of spatial subsets is very large I would like turn it
more operational.Is there a suggestion of how can I do this using pipe like
r.stats mysubset1 | r.reclass mysubset1 mysubset1_fullrange rules= -??
r.stats mysubset1 | awk ‘{print $1,“=”,$1} ; END {print “* = NULL”}’ | r.reclass …
