Description: Woolpert completed a semi-automated method for building generation utilizing new countywide 2009 LiDAR data and existing 2005-2008 orthoimagery. Buildings over 100 square feet were generated and run through a QC process. The final building polygons were developed for the entire ±709-square mile county area. The dataset has had all but those footprints near or within the City of Ann Arbor and contains an average building height.
