Hello guys,

so Germany enacted new laws on flying UAVs and other model aircrafts: max altutude should be 100 m AGL (without extra permissions). Is it possible to display the AGL altitude? The Mavic just shows the ATO (above takeoff) altitude which is useless if you fly in changing terrain. Since this thing has GPS and GLONASS data along with a barometer it should be possible for it to measure AGL? Otherwise  can't really eyeball the 100 m above ground, maybe it's just me

That's relative, and not absolute altitude, which is the issue here.

It is. If your on a mountainside 800ft up and decided to fly that 100 meters still pertain to your ground level.

Take a look at Litchi.
It now includes "RTG" mode. Look on YouTube... https://www.youtube.com/results?search_query=Litchi+RTG
It uses Google Altitude/Elevation data..
But be aware the accuracy is dependent on location.
It can vary from a few meter's up to 30mtrs
It's most accurate in the US.
So you need to do some local tests...

Problem is flying over steep terrain. Big Waterfall - take off at the top, take aerial , then need to descend x meters to not violate 100 m AGL. The Mavic would only show me the altitude delta from takeoff point  not the actual distance to the ground elevation.

Thank you this might be what I need! Is Litchi App worth the 25 €? Would get it if it is better than DJI GO official app.

Difficult... depends on your needs. I was lucky, I got it in the sale a few weeks back.
In comparison to cost of Mavic, it's a small price...

The big plus is you can do all the routes/waypoints off-line on your PC/Laptop @ home on the Mission Hub.
