The camera has no GPS. I record the geodata of the trail with a Solmeta GMAX data logger. The GMAX also records compass data. But these are terribly inaccurate.
So far I have used Geosetter to copy the geodata to the exif file of the photos. Then I used Geosetter to drag the viewing direction with the mouse image by image into the right direction. Very exhausting.
The pictures I edited with Mapillary_Tools today were not provided with compass data by me or Geosetter. (Check mark in the corresponding function of Geosetter removed.) Only the GPS coordinates were entered into the Exif file.
But I have also added compass data to the images with Geosetter. These inaccurate compass values are in this case unchanged in the exif file after processing with Mapillary_Tools.
