Hello,
I have some raster layers and I want to get areas and percentage for each pixel value or range. How can I do that in Arcgis?
Thanks.

If they are not floating point grids, then this should be already calculated in a .vat file for each GRID. Don't remember how to easily get access to that one from ArcMap, but I am sure you can from ArcCatalog. From the GRID prompt in Arc workstation it is extremely easy, and I have a script to export this file to dbf (so that I can use it from excel/access) if needed.
