I have the recollection that GPS height can be woefully inaccurate, maybe even as much as 70 (units forgotten but either ft or metres) for a shot or video taken within 5m of the sea's surface and was reported an being WELL below sea level.So I just subtract the the local asl and have my flight agl.
Unless the Air 2S does things differently from all other DJI drones, it will have two different heights in the image metadata.The exif data altitude is inconsistent with the flight data altitude record.
It seems that the exif altitude date is recording ASL data, not AGL data. Is this a correct understanding?
That image doesn't have any XMP metadata, which is where both heights are usually found.Here is one in which the exif shows 184 m, but I was flying with 394 feet as limited in my dpi fly settings for max flight altitude. 394 feet is 120.09 meters.
The local ASL 198 m with is listed as 650 feet asl.
The arithmetic does not add up.
And I had 17 sats on line as I recall.
You could upload the dng file to Dropbox or similar and post a link to it.The original File is dng.
I cannot upload it here for some reason but when I look at it in Bridge it has the same info as the jpg file I uploaded. Am I doing something wrong in my upload attempt?
I use specialised software to show all the metadata, not just the abbreviated selection that Photoshop displays.I am flying a mavic 3 with the supplied control and an android phone.
In "AdobeBridge 2022", I see nothing like what you have here, and Bridge is supposed to show this data.
Something did but I don't know what. .. the whole of the XMP section was blank, not just the small part I posted.The only change in the substance of the file I sent you is that the dng was saved as a jpg file. Would that remove the data you are looking for?
Another approach would be to shoot a test jpg and post that.I have no other cloud storage.
What program are you using?
This jpg is taken 5 meters agl per the control, but the exif data shows 115.78 m.Picture Information Extractor - EXIF IPTC | Picmeta Systems
