GPS positon is displaced while good in PureMaps
I discovered this issue a week ago, while taking pictures outdoor for OpenStreetMap (via Mapillary). I enabled GPS and waited until it was ready. I continuously checked my location on PureMaps and it was pretty exact: 1-5m.
But when I later uploaded those geolocated pictures to Mapillary, they were shifted about 20km to the south. Manually looking at the GPS meta data of those photos confirmed this shift.
Is this a known issue? I'll try the next day again to gather more information about this problem.
