Description: This data set is a collection of polygons representing the roof line of built structures wholly or partially within the State of North Carolina political boundary. The data were collected by first contacting each of North Carolina’s one hundred (100) counties and requesting existing data in the summer of 2009. Forty nine (49) counties provided building data. Of those 49 counties, only half were considered complete datasets. The remaining structures were collected using the best available orthophotography. Buildings were collected starting at the coast and working westward. Only structures with an area greater than 1,000 sq. ft. (by visual inspection) were depicted with a polygon at the roof line. Structures that were less than 1,000 sq. ft. may have been digitized, based upon best judgment practices and those which appeared to be permanent structures. The building footprints are closed polygons with a unique identifier and have the square footage calculated. The polygons were not required to be rectilinear (i.e. interior angles = 90 degrees), but they should give an accurate representation of the building when viewed at a scale of 1:1500 in ArcGIS. Additionally, the building footprints were conflated with county parcel information (please see IP14 “Developing Building Footprint Data for Risk Assessment”).
Copyright Text: This data set was developed for the North Carolina Floodplain Mapping Program. Additional data development support was provided by ESP Associates, P.A. and AECOM.
