Hi:
I have a track that the GPS has recorded an incorrect elevation, it's about 100m difference to another track that I recorded a month or so later (how odd is that??).
Anyway... I know that RC can get the elevation from geoNames.org (and it works well -- reduced the elevation to something I'd expect), but my concern is that if I did that for the whole track then I'd "lose" what the GPS has recorded. Does that make sense, or is that assumption incorrect??
So, what I was wondering is if it'd be a better alternative to have a "tool" to adjust the track's elevation by +/- n metres? Say my first point is 117m too high I could adjust all the track's points by -117m (thereby keeping the on-the-ground relativity of the recordings).
