The Nuvey exports all its tracks in an GPX. So far so good, no problem. But ... the elevations in these are wrong. They are not corrected for the geoid, so in flat coastal areas in Western Europe they are typically about [B][I]40 m below sea level[/I][/B]! In my MS Access app (described in other thread) I apply a geoid model to correct for this. Once I wrote a mail about this to Gôrmin. No answer. IF / FF/ HF
