OpenTrails

by Code for America, The Trust for Public Land, GreenInfo Network, Trailhead Labs

The Open Trail System Specification (OpenTrails) defines a simple, common format for public trails and associated geographic information. OpenTrails allows public land agencies to publish their trail data and developers to write applications that consume that data in an interoperable way.
