Tom: thanks, I know that the recorded tracks might be off. I noticed several times that at boot time the Garmin made big jumps in heights and location. The hike i made was close to the steep side of a couple of mountains so the readings will be off.

On first glance in OSM the tracks were sometimes on and sometimes far off the OSM. My guess is I can disregard my tracks but use them to hone my drawing skills and consider the tracks as a valuable expierience.

So: thanks for your kind message and thanks for the warnings.

Paul
