In recent releases of DJI Go 4, Altitude is captured in the realtime video metadata recorded in the video's subtitle sidecar file (.srt file). These SRT subtitle files are created automatically when the Video Caption option is enabled.
The altitude recorded in this data is the real altitude above sea level (ASL) at that particular lat/lon. It is NOT the height relative to the take-off point, which is what is displayed in DJI Go 4. See attached screen shot.
When flying to remote objects such as mountain tops etc. it's very useful to be able to see the height ASL as you are flying, rather than the height relative to the take-off point, because it's easy to know the ASL height of these landmarks with great accuracy from geo/topographic map sources.
Eg, I want to fly up to the peak of a mountain top I know with certainty is 452m ASL. There is a ruined castle on top I want to film. It would be very useful to be able to see the height ASL in DJI Go 4 as I am flying. That way I know how close I am to the summit.
I know others have posted solutions whereby you first measure your height ASL at your takeoff point via some external means (eg GPS or topo map) and then keep adding that to the height displayed in DJI Go 4 to get your height ASL. However, doing this mental calculation is a big distraction from flying / filming and is error-prone.
What I am asking is if anything knows a way to get DJI Go 4 to display the height ASL - exactly the same way it's recorded in the Video Caption data. Obviously, the aircraft or the controller knows this information - else how does it get into the Video Caption data?
If it cannot, I think it would be a great option for DJI to add to a future release of Go 4.
Thanks in advance.
