I would like to translate tracks from Garmin tcx files (courses) into
GoogleEarth kml by retaining only linestrings and a single point,
corresponding to the start location of the track. I tried to get such a
result by using the option 'points', setting it to 0 or 1, but it seems that
one either gets no points or gets all the points, resulting in a lot of
placemarks and confusion in the GoogleEarth output. Is there a way to get it
Also, is there a way to get a kmz output?
