These images are VERY early prototypes of the game map. What I have done is to re-create the building scale and position. Because the video game scale is 20% larger then the real world a map can sometimes end up feeling too small or too large. There are set objects in the video game world such as cars or doors. These help to ensure the scale in the game matches the feel of the real world. Effectively making the map 1:1 scale compared to the real world. The games wide viewing angle skews the perspective a bit, but as far as props and traveling around the map the scale is spot on.
I will be taking photos on-site on Saturday, once I have my own reference photos the amount of detail in the map will greatly increase.
