资源简介：
More Metadata Road Casings are a base map data layer derived by automated processes and processed for cartographic representation at 1:2400 scale. Captured as polygons, these features represent roads, parking lots, driveways, runways and a unique Bicycle/Equestrian trail, the W&OD Railroad Regional Park, as seen from above and are mapped to National Map Accuracy Standards (NMAS). A separate item or field will capture surface permeability attribution (paved or unpaved) for each feature.
