terrain

Hi, I am a surveyor and plan to use Phantom 4 for mapping. I am looking for mission planning apps that support terrain following or terrain aware as they call it. The ones that I found are Map Pilot for iOS and DroneHarmony for Android. Are you aware of other apps that support this feature?

I am new to the whole drone thing, having acquired my first drone - a Phantom 4 - about five weeks ago. Since then I've been clueing up avidly on the Mavic. A truly impressive machine indeed. Well worthy of the moniker 'magic Mavic'. But am I tempted to swap my P4 for a Mavic? Most definitely...
