So I am currently creating a land cover map of all of PA. All of my counties will display except for one county. It doesn't even appear in ArcCatalog when the preview of the raster is selected. I reran maximum likelihood with the same signature file as before and got it to appear for a split second and then it went away and won't reappear. When I google this it says to adjust the display quality but that doesn't help. There is also no scale extent either. The only time it will appear is when I'm zoomed in past 1:8000 but again, I don't have a minimum or maximum scale extent set. Was wondering if anyone else has had this problem?
