[Gpsbabel-misc] Convert igc to kml altitude problem

[<sim...@it...>]

Hello

I am using 1.2.6. (win XP). My command is:

gpsbabel -t -i igc -f 57HXH2J1.igc -o kml,lines=1,points=0 -F 57HXH2J1.kml
or
gpsbabel -t -r -w -i igc -f 57HXH2J1.igc -o kml -F 57HXH2J1.kml

I found somewhere in list example with lines and points. This produce 
different kml but I haven't find any explanation of linse and points 
parameters. Where I can find expalanation?

My real problem is that altitude data is 0 in both examples. The same 
problem exists if i convert gpx to kml.

Here is part of igc I am converting.

Best regards

Simon
