Hi all, I'm new at using ACRMAP 10.2. I can find the slope and the aspect of what im doing but I need to add them both together, What tool should I use, Raster Calculator or Math. I'm also finding it difficult to turn a .shp file into a raster file, I keep getting the error: that the file is not a supported feature type. I have googled this and can not find the answer, Am I missing something or doing something wrong. Thanks Any help will be very much appreciated.
