Volunteers Map Trails with GPS

The 19th edition of the Connecticut Forest and Park Association’s “Walk Book” was generated by volunteers with GPS receivers; it took them three years to cover approximately 1,200 km of trails. With 40 per cent of the trails on private land, accuracy was critical. Via GeoCarta. (By the way, have I mentioned how impressed I am by GeoCarta lately? Roger’s doing a bangup job over there.)
