How do I modify a baselayer from Esri?
I found a great one for my region (much better resolution than the one I was given) but it is way too big and I want to cut out the ocean part of the raster so I just have the city map. It is sort of like what you would see with google earth. I would also like to use it for my ArcScene to make nice 3D images but it does not seem that is an option.
I am a bit of a beginner.
