Using ArcGIS 10.4
I have a polygon shapefile with many columns, one is called "coding". It includes pure numbers like 31001
Now I need this as a raster with this code as the value. So I tried, as usual, the "feature to raster" tool. It worked fine. It shows me the values as stretched though. Whenever I try to change the symbology to "Unique values" ArcMap crashes immediately. Also I cant reclassify it, because it wont show me unique values. But that is exactly what I need to do, because I need to group certain codes into one. Any ideas what to do? Is there something wrong with the raster?
