The National Register District GIS Project (NRDGIS) was designed to take data concerning historic districts within the state of Ohio in paper form and convert that information into digital data for inclusion into a GIS system.
In addition to the data being available for internal staff use, the National Register district data is being made available over the Internet for use by the public. To accomplish this task a comprehensive examination of National Register files was performed within the Ohio Historic Preservation Office (OHPO) to identify existing data and to ascertain how much data might need to be collected externally or in-house.
It was recognized early on that while districts entered into the database during the mid-80′s contained sufficient scholarly information, the lack of individual address for some of the large, well established districts was going to be problematic.
This research was made possible through Grant MT-2210-9-NC-34 from the National Center for Preservation Technology and Training (NCPTT).
