These images were captured on November 26th 2020 by my son Fletcher with his DJI Mavic Pro drone. The flight was over a back portion of the Penfield High School parking lot and tennis courts.
An orthomosiac photo was created using OpenDroneMap and was then re-saved as a simple JPG image shown here. One can see jagged lines on the tennis court, in the parking lot and on the running track. Reprocessing the images and/or flying with a more complex flight path may be needed to improve the quality of the orthophoto.
