I have slope percent varying form 0 to 25 percent. Now I want to give a value for each slope percent. For example, if my slope percent is 2 % , I want to assign a value of 10. As a matter of fact, if it is a vector shapefile, then I can easily add a column for assigning those values in the attribute table. But since it is a raster image, I don't know how to assign those values for every slope percent. Please tell me how to do it ??!
Reclass... You will have to take what I assume is continuous slope data and determine categories and then run a reclassification tool to assign the slope ranges new values. I believe you would need to have spatial analyst to do this in ArcMap. I'm not sure about some of the other products.
