GRSM_ROADS

This is a vector polyline file showing roads at Great Smoky Mountains National Park (GRSM). The road system a Great Smoky Mountains National Park is one of the most important man-made features of the Park. This dataset represents the most comprehensive inventory of both locational and attribute information about the road systems to date and is considered on of the most important base data layers for the Park. As such GRSM staff will strive to the both spatial and attribute information stored within this dataset up to date in order to best reflect the current status of the road system at the Park. Only roads which are open to the public are contained in this dataset. Other roads, while known to the park to exist and clearly used for access to permeant features (e.g. cemeteries, overlooks), are not contained in this dataset due to the parks desire to ensure safety of visitors on park roads. These data are formatted for use by park staff in the park 1:24,000-scale topographic map series, and are classified using the "FCSubtype" field, which classifies a road segment based on primary use. To show the location of Roads at Great Smoky Mountains National Park. The intended use of all data in the park's GIS library is to support diverse park activities including planning, management, maintenance, research, and interpretation. These data are authoritative data published by the National Park Service.
