calculation of waypoints for aerial survey

Posted by UAVOZ on October 3, 2012 at 5:24am

I know some basic of aerial photograph for mapping and survey but I 'd like to know if there is a fomula to calculate waypoints in function of airplane height, track spacing, area coverage etc. Where can I find sources to guide me for this formula? Thank you.

    Hi GeoBlu,

    MP planner has a nice tool to calculate your coverage based on lens and digital back.

    Is it the MAP TOOL > CAMERA ?

    If yes, could you explain how to get usefull values from it? Example, I'm about to use the canon sx260 hs camera.

    Thanks

    or

    you can fly in stable mode and take a photo at 100' above ground and measure the image size.

    once you have the image size, you can develop your waypoint distances based on a forward gain percentage. Pending on the the terrain or features on the ground you can apply a 60%-80% fg strategy for image overlap. I would recommend 60% or better. You apply the same strategy for your sidelap as well.

    I recommend the "manual of photogrammetry" for a detailed understanding of the mapping industry.

    send me your image coverage area and I can develop your math if you need help.

    good luck :)
