Cultural Resource Data Exchange Standard for Historic Districts Represented as Polygons (crdist_py): Adopted
Knoerl J. 2010. Cultural Resource Data Exchange Standard for Historic Districts Represented as Polygons (crdist_py): Adopted. Cultural Resources Subcommittee of the NPS GIS Council
This data transfer standard describes a structure for historic districts depicted as polygons. Multiple feature geometries may coexist for the same district as a result of overlapping surveys each with their own particular purpose and bias. All historic districts identified on cultural resource inventories of the National Park Service are covered by this data transfer standard. Attribute data are intentionally limited to those necessary for spatial data maintenance and feature level metadata. Data from external database systems are intended to link with these data to provide basic feature attributes. The means to maintain unique identifiers for each historic district (CR_ID), Survey_ID, as well as unique geometries associated with that feature (Geometry_ID) are through the use of Globally Unique Identifiers (GUIDs) assigned by the database. Information about the genesis of individual polygons is documented by feature level metadata fields in the spatial attribute table.
