I have problem with track recorded with GeoTracker on my Android. Exported track, either in any of given formats: gpx, kml or kmz, is not visible after certain zoom level - scale 1:6.141 (I am using QGIS v2.18.5), and I must note that this is only happening with linestring, not points. Option to set scale visibilty for selected layers in QGIS is not enabled, so QGIS is not a problem. I also exported all the files into shapefile just to try if it would maybe work, but it is still not visible, because logically I guess it withdraws attributes from the original file. I ve been checking out visibilty in files itself, however it states 1. I didnt have problem with track I ve recorded after this one, where configuration and options were exactly the same. I need to be able to edit track somehow.
