Which altitude tag does WebODM pull from?


Very quick question, but which altitude data does WebODM pull from when the EXIF contains multiple altitude fields?


DJI’s default altitudes are rubbish, but you can overwrite them with corrected ones, so I’m hoping it pulls from the GPSAltitude Field, and not the absolute altitude field.

We favor DJI’s vendor specific XMP tags (which are the higher precision one for those cases where the firmware writes lower resolution values in the standard EXIFs).

OK good to know, I will remove the DJI altitude tags then as I am overwriting the EXIF data with higher resolution tags in post
