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?
[EDIT] I have uploaded Pic1 which shows zoomed to the layer extent ('GPX tracklog export'). Pic2 is when it has zoomed in with mouse wheel and part of the shapefile has diappeared. Note these are the gpx file tracklog exported as a shapefile.
