The transportation feature service is a hosted feature service that covers the continental United States, Alaska, Hawaii and Puerto Rico. It is designed to be used for offline field use as a reference. The data contains the TrailNFS_Internal EDW data set and is delivered through the Forest Service Enterprise Data Warehouse (EDW). Data is refreshed semi-annually April and November by the EDW and the Geospatial Technology and Applications Center (GTAC) in Salt Lake City. Data consists of Forest Service authoritative data, and authoritative data from other government agencies. In addition to filling mapping needs the map is designed to help support data management and national data efforts.
This dataset includes only existing National Forest System Trails that are under the jurisdiction of the Forest Service. Each feature represents a segment of a trail, along which all of the attributes are the same. Segments are created by generating linear events from trail feature classes and the Infra II_TRAIL_VISITOR_INFO_MAP_V table. Infrastructure (Infra) is a collection of applications which house information related to an assets managed by the Forest Service (including but not limited to, Roads, Bridges, Buildings, Water Systems, Waste Water Systems, Dams, Trails, and Recreation Sites). The II_TRAIL_VISITOR_INFO_MAP_V table contains fields representing trail characteristics. This published data is updated nightly from transactional tabular and GIS data maintained by the individual administrative units. This data is intended for internal Forest Service use only.
