Here is a snippet of a digital mapper's dream. The topo and the NAIP imagery match up just fine in ArcGIS. Thought you might want to see an example from a favorite area. I am working with our new chief cartographer to develop the geodatabase for the geologic map. All the units are in, but now we are tangling with the line types and rock body types (more on the latter, later). Look for an upcoming post that shows the preliminary line set, the associated terminology, and explanation.
