I have created a web application that will compute the horizontal and vertical fields of view (FOV) for DJI drones given the diagonal FOV provided in the DJI specifications. This information may be of interest to those using drones to perform mapping services. In addition to the horizontal and vertical FOVs, the following items are also computed and provided (based on the desired height of the drone, desired overlaps, and time between photos):
  • Equivalent 16x9 video FOVs
  • Horizontal and vertical coverage
  • Front and side overlap
  • Horizontal distance between photos (parallel flight path distance)
  • Vertical distance between photos (capture interval)
  • Required speed
Most, if not all mapping software will already compute these values. So, this data is probably most useful to those who might want to experiment manually with this data or those who simply want to confirm information provided elsewhere.

Details are also provided on how to calculate both the horizontal and vertical FOVs which is not as obvious as some may think.

I do not perform any mapping functions myself and therefore have no direct experience with mapping. If there are any comments, questions, or suggestions, I am open to hearing them.
