A little follow up by hand (and even this could be automated) could establish trail junctions and where they connect to the nearest road (i.e., trailheads).įor example, I did a search on MotionBased for a mountain bike trail in my area. They could decide how many tracks they would need for a given trail, and how much error was allowed before throwing out a track. I see no reason Garmin can’t utilize their MotionBased data to build a better trail map. We still get maps with plenty of missing trails, and they seem to be based on ancient USGS data. What continues to amaze me is that Garmin doesn’t seem to realize what they have. The latter is actually my first choice, since it is (IMHO) the best trail database in the US.
