But Garmin is the US leader in outdoor navigation, right? Your Application may only access and/or collect information from Garmin about a user or the users activities if the user. I don’t imagine for a moment that this would be an easy thing to do it would require quite a bit of effort. The MotionBased team appears to be significantly underfunded, if the speed of conversion to Garmin Connect is any indication. They may not even realize what they have. But here they have this database that may have 90% of US trails in it. Garmin has recently ramped up their topo mapping with the new 1:24,000 scale series, but they are getting a lot of criticism for missing trails, with some reports that it’s worse than Topo US 2008. The next image is a more typical section, where we can see that most tracklogs are coming within about 60’ of each other, with an even tighter cluster falling within 30-40’. We can see aberrations that might lead you to toss one or two tracks. I’ve zoomed in on a section with some of the worst track “noise” below. If you’ll compare this to the Garmin Topo US 2008 image at right, you’ll notice that they only have the upper half of the trail on their map. People take different approach and exit routes, so the trail segment I was targeting is the one on the left side of the image, showing mostly yellow and olive track lines. I downloaded eight tracks, pictured in the image below at left (MotionBased probably has 50 to 100 tracks of this trail). 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.

When planning a new outdoor adventure, I usually search online for tracks that I can download to my GPS.
