Determining GPS coordinates from NEW Google Maps
Google recently rolled out a new version of their Google Maps web service. From what I can tell you can't retrieve a set of GPS coordinates from the new interface. I expect they will remedy that situation at some point. But for now the workaround is to temporarily switch back to "Classic" Google maps and get the GPS coordinates from there. Here's what I did: Shift back to Classic maps (Gear in top right corner, choose Classic Maps, can say "Dismiss" to not make the switch permanent if desired). Right click on desired location and select "What's Here?" A green arrow will appear. Left Click on Green Arrow and the GPS coordinates will appear in multiple locations.
