I recently obtained precipitation normals from the PRISM dataset online. I'm trying to import the ASCII files into ArcMap, but have stumbled across a few issues.
1) I converted the ASCII to raster. I did it first as float, then as integer. 2) The two rasters (float vs integer) had identical values, except the float raster values went to the hundredth decimal place, while the integer raster was just whole numbers. Not a problem; the ASCII is floating point anyways.
My problem then comes in with the attribute table. The float raster does not have an attribute table, while the integer raster does. Can someone help me understand why the float raster didn't create an attribute table, and how I can build one?
My GIS knowledge is rather limited, so basic explanations are appreciated! I'm using ArcMap 10.2.
