Building Footprints in Chatham County, NC derived partially from the QL2 LIDAR data acquired as part of a project in 2015 by the North Carolina Department of Public Safety's Floodplain Management Branch.

The majority of the features in this feature class (roughly 36,500 buildings) were derived directly from the LIDAR data, but a small subset of the features (roughly 7,000 buildings) were copied from the existing 2007 building footprint layer in Chatham Counties' enterprise SQL database. These features were existing buildings in Chatham County that were not included as part of the 2015 LIDAR derived data delivery from NC Floodmap. Some of the buildings were smaller in size than NC Floodmap included within the specs of their project or fell outside the Chatham County grid index. All features were verified to still exist utilizing newer aerial photography to give a more comprehensive dataset of existing buildings in Chatham County, NC.
