Altitude change and terrain.

Hi,
When you set altitude for your flight is that the altitude from your home point, starting point or each point along the path?

Thanks.

I believe it would be from your take off point.

Takeoff

It's the altitude from where your Phantom took off. Your Phantom assumes that altitude is 0 feet.

Under normal circumstances the plane records the home point with reference 0' feet/meter at your home point. From there on it will reference the height above that point (the home point) for the duration of the mission, in other words, the altitude readout you will see on your DJI GO application/screen will be referenced to Above Ground Level (AGL) at your starting point.
As an example if you take off (home point reference height point) from a mountain top and climb to, say, a height of 100 meters, and fly out over a valley, keeping your height at 100 meters, your actual height AGL over the terrain below will now be higher/more than the 100 Meters, that you've kept constant, but the plane has been flying in a straight line at the same level..

Thanks. Would make sense.

Definitely from your takeoff point. Attached is a photo of what happens when hills sneak up on you.

Oh man, that stinks. Fly high I guess.

Thanks
