I’ve been updating OSM for a few years now based on GPS tracks from my hikes in forested parks and adjacent public greenspace in the U.S. State of Georgia. Those updates and a lot more trails created by others in OSM are now incorporated into My Trails for Garmin (free download for PC and Mac).

It is a transparent map, so it sits on top of whatever topo you use on your GPS; my favorite free one is Georgia Topo:

Just over 600 miles of trails added. I’m being conservative with this first update by only adding trails in the 64 parks and adjacent public greenspace areas I’ve edited in OSM. Of those, I consider 17 areas to be complete (and together, represent over half the mileage of the update). They are: * Amicalola Falls State Park * Arabia Mountain Nature Preserve * Charlie Elliott Wildlife Center * Fort Yargo State Park * Harbins Park * Hard Labor Creek State Park * High Falls State Park * Kennesaw Mountain National Battlefield Park * Little Mulberry Park * Miners Creek Park * Mistletoe State Park * Piedmont Park * Red Top Mountain State Park * Skidaway Island State Park * South Rockdale Community Park * Stone Mountain Park * Sweetwater Creek State Park

Periodic updates will be made.

20 km hike to GPS all the trails at Reynolds Nature Preserve in Morrow/Lake City, Georgia, USA. Used a Garmin GPSmap 62s with external amplified GPS antenna. Trails and other features added.
