Land - wrong altitude is used in equations if some trackpoints don't have altitude values

    Hello Uwe,

    If the file actually includes de -1 data, it seems normal that Land reads it, as negative altitudes can be present in some parts of the world. So it is not ignoring the "-1".

    But maybe the file doesn't include "-1" but some other value which is read by Land as a "-1". In that case, we could evaulate this behaviour and try to find a solution. Could please provide this track?

    As you say, you could calculate altitudes by a CDEM, but then you would lose the correct altitude data from the other points. An option would be to split the track in 2 (right click on the point and 'Tools > Cut track here'). Then you can work with the tracks separately (add altitudes from CDEM in one of them), and finally unify again the tracks ('Menu > Edit > Unify tracks').

    The file doesn't include the "-1", Land is showing this value if no other value is apparent.

    OK, we open a private request so you can send us the file. Then we can report the case to our technical team.
