      Hmmm... I wrote a reply and it disappeared. 😞

      Solar North and True North don't necessarily coincide. Maps are set up for True North, not Solar North.

      Solar North occurs when the sun is at its zenith. We generally think of that as occurring at noon but the actual time it occurs depends upon where in the time zone your model is geo-located.

        So, I should reasonably expect real world shadow behavior similar to the shadows generated in a geo-located model if I convey construction staking coordinates based off of True North???

          Yes. I would think you should.

              You're quite welcome. I hope the monument gets installed correctly. You could mount it on a large lazy Susan so it can be rotated to face the sun as needed. Sort of a real life Face Me component. πŸ˜„

                  It might come to that β˜€

                  One more question. The Longitude and latitude appears to be in decimal format. Is that everyone else's understanding? As in 45.37770 degrees not 45 degrees 37 minutes and 77 seconds.
                  Surveyor asked for a clarification.

                    Yep. Decimal format for Lat/Long.
