I am a long time, experienced user of drone deploy and mapping with the app. Nevertheless, I came upon a situation I had not come up yet. I need to map an area of land that lies from to topmost part of a hill chain towards the valley. The highest peak of these mountains are 250 meters above the lowest.
As I have always done before, I plan on setting the starting point for the flight so that I am taking off from the highest point in my flight plan, which will already be 250 mts above most of the rest of the area to map. So I figure that setting a mission flight altitude of 50 mts would be perfect since that height enables me to fly almost most of the mission 300 meters above most ground level.
The problem is that the area to scout is 200 hectares, so if I set the flight altitude to 50 meters and take off from the highest point, Drone Deploy thinks I will only be flying 50 meters above ground level and gives me a 409 minute, 29 battery flight plan.
On the other hand, if I take off from the lowest point and set a flying altitude of 300 mts, DD gives me a 38 minute Flight Plan on 2 batteries.
Is there a way to tell the app the set mission flight altitude is AGL and not ATO??
