Tips on navigation:
To see the filming locations up close, zoom the google map to maximum, then click on the location you want to see. Depending on your platform you will get a closeup birds eye view, or a 3D view, and can rotate the map and any other features you would normally have in GoogleMaps.
You can drag the StreetView icon to the nearest street to see the location from street level as well. In some cases you can even ‘look inside‘ if there is a blue marker in streetview. (If switch into real Google Maps and you can even go back in time – handy for locations that have been demolished!).
To see more of the map you can minimise the locations panel, as well as close the location detail popover if it is covering the building you want to see.
