I have these four layers of roads that I have to clip into a county layer in ARC GIS10.2 that I have to clip to another layer (which is the county). I have absolutely no idea how to clip all four layers at once. Is there a way where I can clip them all in at once?
You could use batch modus or a model?
Clip (Analysis) only supports one layer at a time You could create a model as shown in Help file topic
There's a small script for the toolbox:
