The document discusses the Intertwine Alliance, a coalition of organizations working to improve access to information about parks and trails through data standards and applications. It promotes OpenTrails, an open data standard for park information used to build visitor apps, and OuterSpatial, a platform providing easy access to park data. The Regional Land Information System database contains over 3,000 miles of trail data now available through OpenTrails to help developers build maps and apps for visitors to access outdoor information.
