Ted,
I will go to my corner now and let my GIS career rot on the vine...
The first part is essentially what I have for the Overpass/Underpass classification. The situation I have is not about bridges and selecting points within a buffer isn’t relevant either because I am working with an Intersection Points layer based highway Postmiles created by a Dynamic Segmentation application using the California State Highway System. I do manual identification once I have the Points layer created based on Postmiles.
I don’t have Roads and Highways yet, and you would think the tools in ArcGIS Pro would be able to detect and classify types of intersections but essentially they are high end graphics tools and not related to the spatial data (i.e., Lat/Long point location).
If Bridges and other features can be extracted from imagery, why isn’t there a way to do feature extraction from Google Earth? Or can I only use another type of imagery?
