Manual tests

We did a test in Brooklyn to see how far people need to be spread apart for the pictures to still overlap. We started in a tighter grid, took a pictures simultaneously, then moved out from the center, following the stops as below. We had a very low cloud ceiling, but still a lot of overlap in our images.

Each time, we faced North, positioned the phone parallel to the sky, and took two pictures, one vertical, one horizontal.
