National Park Service Jurisdiction in the District of Columbia, National Capital Region NPS
These polygon datasets represent the jurisdictional park boundaries for the National Park Service (NPS) units in the District of Columbia. These boundaries are somewhat equivalent to tract data whereby individually legislated areas are maintained as separate polygons. For a dataset where those polygons are dissolved for a cleaner appearance on maps, see Park Management (Jurisdictional) Boundaries, National Capital Region NPS (https://irma.nps.gov/DataStore/Reference/Profile/2305168). These boundaries identify the land the is owned and managed by the NPS including which NPS administrative unit manages it. This boundary is equivalent to the type of boundary that is displayed on park brochure maps.
