Look at this place, it’s beautiful.
The Cinefex article on Thor: Ragnarok provides additional details on what appears to be a relatively simple location, spotlighting at least three elements that made up the finished shot.
Field
Cinefex 156 indicates the scene was shot in a “field in Atlanta,” so the assumption is that the field outside Pinewood Studios was that location. This is only conjecture.

Some of the coastal topology of the Norway scenes was based on Port Talbot, Wales, Anthony Hopkins’ childhood home, according to Cinefex 156.
