>>1922948City does it every 2 years for general planning purpose. They have them taken late April before the leaves open so they can see as much of the ground as possible. The camera setup on the plane takes a straight down image and one facing north south east and west at an angle. With the right software they could make a decent 3D model with the 7.5 cm resolution.
Since I knew generally when it was going to happen I scanned through the ADS-B history until I saw a plane flying patterns and saved its flight path. Then loaded up that path and my ride for the same day in Google Earth and was able to scrub through until I found a spot we passed at the same time.
