Know what you are ordering before the drone takes off
The most expensive mistake in a drone assignment happens before the flight: choosing the wrong output. A DSM where you needed a DTM. An orthophoto without the control points your land surveyor expects. A thermal capture on a day when the temperature difference was too small. Here you will find, for each technique and file format, what it does, when it makes sense and where its limits lie.
