These seems really elementary, but I can't find an answer anywhere.
I have a raster dataset that came with a colormap (USGS Land Cover).
When I display this raster in ArcMap 10, 255 "values" show up in the legend, even though only 14 pixel values are assigned colors. The rest show up as black, white, and grayscale. How do I get rid of these nonexistent colors?
I just want the 14 colors that appear in the map to show up in legend in Layout.
I do not recall this being a problem in v. 9.3.
