Flight Planning


Unmanned Aerial Vehicles remote sensing technology is an important means of spatial data access, which has advantages of long endurance, real-time image transmission, high-risk areas detection, the low cost, the flexible etc, and complement the technology of satellite remote sensing and manned aerial vehicles remote sensing.

Steps to Completion of a Photogrammetric Project

  1. Determination of mapping limits
  2. Select scale and contour interval
  3. Plan flight
  4. Plan the ground control
  5. Place premarks
  6. Survey premarks
  7. Aerial photography
  8. Survey calculations
  9. Check aerial photography
  10. Aero triangulation
  11. Base sheets
  12. Map compilation
  13. Map checking
  14. Map corrections
  15. Map acceptance


For the flight plan, the planner needs to know the following information, some of which he or she ends up calculating:

  1. Focal length of the camera lens;
  2. Flying height above a stated datum or photograph scale;
  3. Size of the CCD;
  4. Size of CCD Array (how many pixels);
  5. Size and shape of the area to be photographed;
  6. The amount of end lap and side lap;
  7. Scale of flight map;
  8. Ground speed of aircraft;
  9. Other quantities as needed.
