OpenStreetMap
My first succesfull upload of, I thought, one track turned out to be all active logs from Yosemity from the last three days. I still have to learn to rtfm.
To do: clean up the active log. After that check the OSM map if it is any good compared to my tracks and poi's.
The bad: I can't do that on my crappy laptop here in the states. This has to wait until I'm back in the Netherlands.

Just a friendly warning: be skeptical about the quality of your tracks, no matter which GPS you've used. Yosemite Valley is one of the more GPS hostile environment...
I've had tracks recorded with a Garmin Edge 305, a Garmin Vista C and various iPhones off by literally hundreds of meters. There seemed not to be any correlation with the presumed quality of the device. Eg sometimes the iPhone was much better than the Edge. IOW always correlate your tracks with aerial pictures.
In any case, Yosemite Valley trails are relatively complete except for trails on the north side. Other sections of Yosemite are often very sparse...

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.
