How Accurate is Garmin MapSource?

About four months ago I bought a Garmin Legend Cx hand held GPS receiver and the Garmin Mapsource Canada Topo discs containing the topographical maps for all of Canada. I was surprised that most of the more popular trails in areas like Banff and Lake Louise appear on the topographical maps. For most of Kananaskis, which is where I prefer to hike, the trails are not included. Not a big deal because I did not expect that the maps would be included in the first place. As far as accuracy, mountain trails are not highways, depending on things like erosion, fallen trees, I would expect that the location of the trail would not be 100% accurate. Also, the sun, tree cover, cloud cover, and several other things interfere with the quality of the signal received by the GPS unit.

For this post I am only going to refer to hikes for which the quality of the satellite signal I was receiving was excellent.

Marsh Creek Trail near the Cave and Basin, which is a World Heritage site, should be a good example where one would expect a high degree of accuracy from Garmin.

The thin dotted line is the trail. It is tough to see in this post so I am sure you can imagine how hard it is to see on the 3x6 screen on the hand held. About 20 of the 140 recorded points are on the trail as reported by Garmin. The track is off the reported trail by up to 75 meters. Really not a big deal because the trail was easy to follow on the day I did the hike. Interestingly, the Bow River seems to have moved but then again, rivers do that.
