Preservation Office’s New Online Application Maps Historic Development and Preservation of DC

I thought this was interesting, yesterday the Historic Preservation Office announced the launch of HistoryQuest DC, a GIS-based web map that provides historical data on approximately 127,000 extant buildings in Washington, D.C. The Office of Planning’s Web site provides the following description of the application:

The application, HistoryQuest DC, is an interactive GIS map that provides historical data on approximately 127,000 extant buildings in Washington, D.C.  The map offers several operational layers of information for the user including historic data on individual buildings, links to documentation on properties listed in the National Register of Historic Places, information on historic residential subdivisions, and the identification and boundaries of the L’Enfant Plan, and the city’s Squares, and Wards. The featured layer in the map—the Historical Data on DC Buildings—provides information from a variety of sources on original dates of construction, architects, owners and builders of the city’s historic buildings.

The application also includes a Query tool that allows the user to analyze the historic data within a specified geographic area or city-wide.

This application has evolved out of the DC Historical Building Permits Database project and is still a work-in-progress. Anyone with additional information or knowledge about specific buildings that will enhance, enrich, or correct the map, please use the “Propose Data Change” on the banner at the top of the map, complete and submit the GeoForm.

By using the search box, anyone using the maps can quickly get to basic data on any property, including when a house was built and who the architect and builder were. The various layers also can generate some interesting maps. In addition to historic landmarks, the following maps show some examples of the maps that it generates.

history-quest-1(In looking at the map generally, it is easy to quickly get an idea of how old section of DC are. The older the building, the darker the color.)

history-quest-2(In exploring the various layers, one option is to show existing historic districts.)

history-quest-3(Another interesting feature, many of the original subdivisions have been recorded.)
