There is roughly about 24-feet of island surface visible between fedora man and purse woman. There is roughly about 24-feet of island surface visible between the island’s Elm Street curb and the island’s Elm Street Extension curb on Weigman’s line of sight that runs between fedora man and purse lady.”

The image below shows the line of sight with fedora man inline with the gated opening behind him. The black arrows are meant to show the space between the island’s Elm Street Curb and the island’s Elm Street Extension curb at this line of sight.

The images below are from the Roberdeau map. The first one shows the (red) line of sight with (red) cross hatches indicating the two curbs referenced above. The (black arrows) distance between the two curbs is roughly 24-feet at this specific line of sight.

The image below is the scale of the map that I used to approximate the distance.
