GIS Metadata

NOTE: This layer is from Pima County and updated periodically. It is filtered to not show sensitive data. The City of Tucson has permission from Ian Milliken at Pima County to distribute it publicly.

This layer replaces NR_DIST. The National Register of Historic Places is the nation's official list of cultural resources worthy of preservation. The Register includes buildings, districts, objects, sites and structures. The Register is administered through the National Park Service. NRHP_D displays districts; buildings, objects, sites and structures are contained in NRHP_ND. Known Errors/Qualifications: Resource boundaries are as determined by Pima County Cultural Resources, not the National Register, which lists resources with addresses. Lineage: Geometry and attributes updated by I. Milliken based on thorough review of NPS source documents; new schema created, data loaded and metadata updated by E. Glenn. Spatial Domain: Pima County Region Maintenance Organization: Pima County ITD GIS Maintenance Description: As NRHP Districts change, Cultural Resources staff will update the geometry and transfer new shapefiles and attributes to PC ITD GIS.
