Re: [RC] [RC] GPS advice - Maryanne Gabbani

Mine will sometimes add some weird stuff in as well and I can tell that they aren't right. Mine usually take the form of a backtrack where I know that there wasn't one.  When I'm gpsing a trail in the countryside I can usually see it on Google Earth so I know where, in fact, I was riding rather than where the gps thinks I was. I paid $20 for Google Earth Plus so that I can upload my gps tracks onto Google Earth. Then I follow the tracks and edit them for accuracy. Where I have problems is on desert tracks because the desert doesn't really show up very well on Google Earth.

OK guys, joining the virtual classic did what I'd hoped....it made me
learn to use the GPS I got *last* Christmas. However, here's the problem
I'm having. When I turn on the odometer it seems very accurate. The
signal is working and it keeps a very steady tabulation of distance
gained. For instance, 2 days ago it said I rode 8.82 miles. This was a
very twisting turning trail that intersects often (picture spaghetti
bowl). So...then I come home and I download the "track". The computer
simplifies the track and several times it cuts across country to join two
points but totally changes my path. Kinda scarey when it shows me angling
towards the house off the side of a vertical ridge...I can imagine a
horse bolting off that but the GPS makes it look like a prediction. :-P
Anyway, the "track" said it was 7.36 miles rather than 8.82. Besides
ripping me off mileage wise it is making the "map" of my ride inaccurate.
I set the interval for recording points at .02 (miles?)  Is there any way
to get it to not "simplify" the track?
