National Register Datasets


The Delaware State Historic Preservation Office maintains statewide GIS datasets that show location and cultural/management information on historic properties (buildings, sites, structures, objects and districts) listed in the National Register of Historic Places for Delaware, including properties which are also National Historic Landmarks.


Delaware Hundreds


"Hundreds" are a geographic division, smaller than counties and roughly equivalent to "townships" in Pennsylvania and New Jersey. Delaware is the only state which currently uses this division. There are thirty-three hundreds today. The most recent changes to hundreds were in the 1870s when the last two were established: Gumboro in 1873 and Blackbird in 1875. Prior to the 1960s, hundreds were used as voting districts and as units for reporting taxes. The sole use of hundreds today is in property tax assessments (tax parcel numbers are assigned by hundreds) For the full story on Delaware's hundreds visit the University of Delaware Research Guides


All of these datasets are now available for download on the Delaware Geospatial Data Exchange . Anyone can browse the list of public datasets in the Data Exchange at: https://dataexchange.gis.delaware.gov/dataexchange/download.aspx To view HCA data at the top of the dataset list, use the Dataset Filter, By Group, check DHCA, and Apply.
