Thanks for your quick answer. In fact, the procedure you suggested me is the
same I'm testing, but the error "iNPUT MAP IS OUTSIDE CURRENT REGION"
continues on. I've tried all definitions I can image of output region,
without success.. I've some problem, and I don't konw what!!!
I did a deep review of the map I've imported on. I imported the map from a
.ppm and the cout of rows/columns and colors used (my elevation levels are
correct). I note that the header info is not correct, it didn't locate the
map into the input region I've defined,but I tried to change the header
file, run the g.region and check than region fit exactly with my
coordinates... but proj continues whit the same error.
Then, I'm bloqued... I'm not sure too if i'm choose the correct output
projection. Can anyone confirm me if a mercator projection give points with
logitud and latitude values constans in the same row/column of my map?? Or
the correct conversion is a ll projeciton (longitude/latitude)???
Any help or test you can suggest me will be really apreciatted. I re-post
the info of my original map-greyescale image:
