Hola JC, I have discovered that your suggest did work. Thanks. However, it wasn't obvious because my data wasn't showing until I zoomed in far enough into the map. The front-end application, which is a FLEX viewer, wasn't showing the colored raster pixels until zoom level 4-5 click of zooming in on the map. I don't know if this is something I can fix at the .map level. The projection currently defined for this layer is:
PROJECTION "proj=aea" "lat_1=29.5" "lat_2=45.5" "lat_0=23" "lon_0=-96" "x_0=0" "y_0=0" "ellps=GRS80" "datum=NAD83" "units=m" "no_defs" END Cheers, Derek On Fri, Jan 20, 2012 at 1:01 PM, Fuchs Juan Carlos <jf...@indec.mecon.gov.ar > wrote: > Hi Derek > > Try with this for each class you want (just change the expression value and > the color.
