I will be shooting a aerial video of a 25 mile long by 100 feet wide patch of undeveloped forest land. I was wondering if anyone knew the formula to calculated the altitude I would need to fly at to only capture the 100 foot wide path? I'm using a 94 degree FOV camera with a 20 mm prime lens. I hope this is enough info to calculate. TIA.
You may have a greater problem. First you need to program the flight path because at about 3 miles out, you'll lose contact (and control). In sport mode at maximum speed of 44 mph, your battery will be drained at 21.5 miles, with 28 minutes flight time. Then I assume you want it to return? Enjoy the hike.
