Agency wide data pertaining to cultural resources

The Cultural Resources GIS program (CRGIS) has been developing an NPS-wide enterprise GIS dataset pertaining to cultural resources. The data conforms to the NPS Cultural Resources Spatial Data Transfer Standards. It currently includes content from the National Register of Historic Places, legacy Cultural Landscapes Inventory (CLI) and the List of Classified Structures (LCS) data, as well as limited NPS tax and grant-related information.

At this time, the enterprise dataset is available only to NPS employees. Sensitive data have been restricted and is available only by specific request made to the individual parks, programs, or regions responsible for its creation.

Where to access

CRGIS is working to provide access to this data to both technical and novice/non-GIS users through a variety of formats. Advanced GIS users can connect to our SQL database or REST services through their GIS software. Casual GIS users with access to software may wish to take advantage of a custom designed ArcGIS .mxd file that helps to connect to, organize, and symbolize the data for them. Find links to documentation and access points through our webpage.

Additionally, CRGIS produces spatial data related to the National Register of Historic Places as a stand-alone dataset. Currently, the GIS collection includes more than 87,000 properties listed on the national inventory. This work is ongoing and is updated periodically. Public (non-sensitive) data are available for download through the IRMA Data Store and via a web map application. Links to all access points, as well as a newly-updated and informative FAQ related to this dataset are available on our webpage.

CRGIS is working to incorporate all of the NPS cultural resources inventory databases into the enterprise dataset by creating useable spatial data for each program and defining relationships between resources identified in these databases. In the near future, CRGIS hopes to include ASMIS and Heritage Documentation Programs (HABS/HAER/HALS) data into the system.

Additionally, program and regional data editors will be working to update existing data. CRGIS is also working with FEMA to help improve the spatial accuracy of National Register historic district boundaries. Many existing boundaries for districts in Massachusetts and Connecticut have already been updated and additional states in the northeast are set to follow to follow later this year.
