Description: This dataset contains point data that is attributed based on the assessed type of the building as well as the name associated with the marking on the map. Using a simple 1,2 classification scheme the individual spectral signatures were extracted based on samples given to the program that determined whether a feature matched the samples. The raster data was converted to vector by using the raster to polygon tool and cleaned manually. Using feature to point the centroid the centerpoints of the polygons were extracted and attributed accordingly. This is outlined in associated documentation. This is intended as a demonstrational piece for future projects and development as the datasets for the Historical Commission expand.

Description: This data was created for the Prince William County Historic Commission using a collection of historic USGS and other maps. It contains the secondary historic roads as indicated in the maps for Prince William County. Created using line segment creation methods in the editor tool based on the georeferenced topographic and cartographic representations of Prince William County. Each segment is attributed with the appropriate year that the map was surveyed, the map title that it was taken from, and the road names if available in the map; road names also allow for further research into the history of specific roads. The purpose is in the land assessment process by the Historical Commission and the expansion of possibility of field verification and further research into the actual location of the historic road network. First Phase (baseline) finished on 1/17/2019).

Description: The Battlefield Boundary feature class represents the polygon locations of the “study areas” identified in the draft Update to the Report on the Nation’s Civil War Battlefields, for the principal battlefields of the Civil War. The update to the report was authorized by the Civil War Battlefield Preservation Act of 2002 and last revised in 2014.The draft report defined “study area” as the maximum delineation of a battlefield, providing the tactical context of the battle and including all places related or contributing to the battle event. The Battlefield Boundary is where troops deployed and maneuvered before, during, and after the engagement. Feature level metadata entered in the attribute table provides additional information about the source and creation of each polygon. All data was edited for accuracy and consistency.

Description: Historical research by Prince William Count was conducted to identify areas, not descrete areas, in Prince William County that contain or could contain significant known, but ill-defined or suspected historic sites, Civil War sites, historic viewsheds; or contain areas of potential impct to important historic sites if developed. These polygons are used in planning to indicate additional research is necessary to better understand the significance of a particular resource and impact on that resource.The data set was created during the early 1990's.

Description: This is a comprehensive list of all the known cemeteries in Prince William County. Baseline data was collected from a 2003 report by the Prince William County Historical Commission. Polygons represent a 50 foot buffer around a centroid location of a particular cemetery and was collected with a handheld GPS unit in latitude and longitude. The GPS datum was not recorded. Location errors in this centroid data are common and sometimes are hundreds of feet in error. Location data points are corrected on an ongoing basis as new data is reported. This data set should be used to identify the general location of a particular cemetery so a more detailed archaeological cemetery delineation survey can be conducted. This data does not show the limits or extent of burials in a particular cemetery.
