Can someone please help. Have the Etrex Legend. Bought the Metroguide USA 5.0 software on ebay. Came with no instruction on how to transfer from my PC to my Legend. I have the factory supplied cord that came with the unit. Can someone please walk me through this? I have tried using the Save to Device feature with the Legend on and with “Garmin” showing on the “interface” page. It tells me the transfer went through, but it doesn’t, as evidenced by my use of only 2% of the unit’s memory. Thanks in advance. Russ

A good C program for communicating with the garmin is gpstrans (http://gpstrans.sf.net/ ). It works great with my Geko 201. I think there's also a Perl module on CPAN, though I haven't tried it. (I'm not running Debian, nor do I know Python, so I must resort to this :)

Yes, one of the tracklogs in that data dump included a flight from Berlin to London, during which I was able to use the GPS (apart from take off and landing). Keeping the unit on my armrest close to the window, it was usually able to find three satellites to track.

The negative longitudinal values are in London, west of Greenwich (longitude 0).

I just checked your ‘trackpoint’ locations using this calculator.

Wow.

It claims you moved approximately 589 miles in a little less than two hours. Is this possible? Were you personally flying? Can you use gps on a plane?

Further, what’s the deal w/ negative longitudinal values in the ‘trackpoint’ listings?

Peace

Tracklog of GPS in RDF

The Tracklog property in the GPS vocavrary is great. I feel that the rdf:seq and rdf:li is useful for Tracklog.

This looks interesting. I’m using the geko 201 in a buoy to track near shore currents. Since I’m not a programer, do you know of a pgm that works under dos or windows to get the Tracklog Lat. Long. data.

Thank you,

Great work, very helpful. I've tweaked it a little, adding wordnet mappings for the waypoint symbols, see http://www.wasab.dk/morten/2003/10/garmin-geko201-rdf.html
