Track profiles

[wa4phy]

I just got finished reviewing my daily trip trackpoints, and I ran across some stuff in a couple that really amaze me. I have several leg(s) that vary in length from a max of 19.2 miles down to several feet, but the longer legs really impressed me, in that neither altitude, speed, or direction changed in those distances. Of course, that was in the SW, between Roswell, NM and Sweetwater, TX. I recall driving, and looking as far as I could see with nothing between me and the horizon except road, and even commented to my wife that our heading had not changed a single degree in the last 10 miles. You sure can't do that kind of leg length here in the SE, but easy to do out west. The more I fool around with mapsource, the more I find I can do with it. Thanks Garmin for providing it..

Nice feedback, Sam. That sounds like one heck of a road to drive. It would have be interesting the next time you drive it to disable the snap-to road GPS setting. Then download it to MapSource and see how close your track is to the road. I generally find urban roads are quite accurate vis-a-vis GPS and map but I take snap-to roads for granted never knowing for sure what kind of alignment error there might be.

I believe "snap to road" only effects the display on the iQue in real time.

The actual GPS location is recorded in the track log and displayable on the iQue via Tracks or MapSource via DLing the data from the IQue.

I base this on seeing non-road paths when viewing tracks following trips. I could be wrong, but it would be a first :-)
