Choosing Flight Altitude
The tighter the accuracy you need, the lower you will need to fly your drone. The table below shows expected accuracies at varying altitudes, given that ground control is set accurately and represented precisely.
As you can see, as we fly higher, we can cover more area with fewer batteries and less time overall, while compromising some accuracy. It is important for you to consider tolerances and account for the extra time and more batteries it will take to fly at a lower altitude.
Site topography and structures should also be taken into consideration when choosing an altitude to fly at. You want to make sure you are flying at LEAST 100’ above the tallest obstruction on your site to avoid insufficient overlap in your photo data.
