After many hours of hard work, I was able to upgrade my simulation. I was very careful to synchronize the Google Maps top view with the Trump rally footprint which gave me a very good basis. All heights in the Y axis are confirmed thanks to the many good feedbacks I got from this community. Thank you! I will keep this version official for the moment until somebody comes up with compelling arguments to change the vertex parameter. One thing is sure with this simulation: the first three shots come from building Number 6. I am fully open to share all my data, don’t hesitate to ask….
