I have a tcx file, which is missing some altitude values in the beginng, but after a while, those are added to the following trackpoints.
Land is giving the trackpoints with missing altitude values the altitude value of "-1" and is using this values in calculating different values like Altitude Diff. Departure-Arrival;ascent;Distance with altitudes;Mean moving speed ... instead of skipping this placeholder.
I know I can circumvent this problem by asking Land to recalculate the altitude value for each point on the base of a cdem file but this is not the point.
