I have a topo map of the US and want to clip only a certain states out of it. I have tried creating a polyline out of the states I need and clipping to that but the map looks like ****. Is there an easier way to clip out parts I don't need?
You can clip a raster based on a polygon. Clip—Help | ArcGIS for Desktop
Check the box for "Use Input Features for Clipping Geometry (optional)"
You should be able to do that and have it not 'look like ****'. What's happening with the clipping that you don't like?
