Greetings I have an raster file with labels (used r.reclass). Is it possible to export (r.out.gdal in geotiff format) it with the labels?
Thanks

r.mapcalc "new_map=@existing_map"

then export "new_map" to tiff as usual.

Hi

GIonanni Suggested me to use r.mapcalc new=@old_with_labels but I get a map with Nulls.
Is there any way to export Labels?
THanks

Maybe the problem is other. this what I am doing:
1- produce a map
2- reclass this map (image1)
3- apply reclass over this same map to have labels)
Might this be he problem?
Thanks
