Building Additions

Building additions contains additions to building structures that would not be captured as part of the actual building structure. The original data capture of the data in this layer was completed in 2013 using stereo models from the 2009 Virginia State imagery. Subsequent to that an update capture was completed in 2022 using stereo models from the 2017 Virginia State imagery. The most recent planimetric update was completed in 2024 using orthoimagery from the 2023 and 2022 Eagleview Orthophotos. The data in this layer includes decks, patios, pools, and aprons (patios for commercial buildings).
