I need to select the 'common area' in this map, the spot shared by the different polygons.
How can I do this? Do I need to create a new layer from each polygon, then do something to select what is within polygon1 and polygon2 and polygon3 or something like that? I just need to make a raster of the common area, i need to have one, solid selection that includes all of the area that is inside each polygon. Is there a feature to just analyze and select only the common area without having to break down each polygon?
I am a newb to this, please mind my ignorance. Thanks in advance.
