I have 100 acres of land to survey at 100m of height to make orthoscopic map. 50/65 overlap.
How many flights would it take to cover that area?

From my experience you should increase the overlap to 80% forwards and at least 70% to the sides, or greater if you can afford the time, to 80/80. Otherwise you risk ending up with holes in the mosaic, the longer you fly, the more chance the wind will change during the flight, or gusts of wind will alter the flight tracks. Increasing the forward overlap, costs you nothing if the camera can take an image quicker than the speed over ground, a camera that is capable of shooting one per second is enough. Remember that around one in ten images are blurred, or dark if the light levels keep changing, so having more images than you really need is the best way to produce a good mosaic.
Good luck.
Yes I support this, also will try to change the orientation of the strips to the longer side, if the distance is less than 500-600 mts, i would also lower the speed of the Iris+ to get the overlapping at leas 70/70%
Good luck
You can do that with the "Set WP" button in the "Actions" tab in Mission Planner's "Flight Data" view.
Exemple :
Start a mission -> RTL -> Change battery or whatever you need to do -> Restart mission -> Select the waypoint where you left off and click on the "Set WP" button.
Make 4 grids.
I average 13 mins a flight with camera attached.
Here's the actual job. I have 6 batteries.
Is this right?
