it means we have to do more testing, unfortunately. I'm not sure if the
input map scaling is bad, the gpsdrive rendering is bad or different
that what I expected (Plate carrée), the airport data is of dubious
quality, or what.
how close is your gps location on the australia map?
probably need to turn on grid lines in gpsdrive-cvs version and I need
to re-export the .au map from the GIS with embedded grid lines, then
compare how they match up. alternatively, make a grid of waypoints.
how do the included continental maps look for everyone else?
thanks for the feedback,
Hamish
