Wrong reading of GPS data from DJI DNG files
The two DNG files are shot by DJI Mavic 2 Pro. The distance between the camera position of two shoots is no more than a hundred meters. But the latitude difference read out by Darktable 2.6.2, is about 1 minute, or 1.8Km approx. See screenshot1.jpg and screenshot2.jpg.
The GPS data shown by Windows file properties are resonable. See screenshot3.jpg
