Flight modes - terrain

So I’m confused using the terrain in beta. When it asks for the tallest hill and so forth, that is in comparison to what. If your project has a 200’ elevation change, where do measure from? The low point? The high point? Take off point? Please explain. Thanks

From takeoff. If you take off from the midpoint of a 200 foot elevation change it would be 100ft. Keep in mind that if you have that much elevation change you probably want to think about multiple setups because your imagery will greatly vary from the high point to the low point if you get too much of a gap altitude.

If he’s using the Terrain Follow beta app, the altitude should be relatively consistent AGL although vary in EXIF.

Thats what i want to use. So does that mean highest point from the level im on?

Yes, that should do it. AGL
