I have been tasked to take 5 progress pictures of a construction project from the exact same location, elevation, and gimbal pitch with the P4PV2. The object is to show the site before construction, three shots during, and then after construction. These photographs will be proudly displayed in the contractor's office. I would like to be as precise as possible to get the same picture "frame" over several months. I have an idea of where I want to take the shot from, but I will not know any of the location information until I actually fly and frame the shot that I want. I would like some advice, from someone who has done this before, on how to get the same picture framed multiple times, over several months.
