I have imported a .gpx file into qgis and separated the track waypoints using Vector > GPS > GPS tools. When viewing at full extent I can see the original track and component waypoints. However when I zoom in, the track lines disappear but the waypoints are still there. I have tried:
- checking track layer scale dependent rendering is OFF
- exporting track layer as .shp and adding to map
- moving track layer to top of layer stack
- toggling map rendering
but still cannot view track when zooming in. Any ideas?
