failure to write gps altitude in image file
I am unable to set the gps altitude. Basically I read the gps data in python via gexiv2 (GObject-based wrapper around the Exiv2 library)
metadata.get_gps_altitude()
and compare the metadata altitude with gmaps elevation if there is a strong deviation I want to correct for the gmaps value:
metadata.set_gps_info(lon, lat, true_elevation) metadata.save_file()
However the GPS altitude in the picture file remains unchanged.
Any help is appreciated
