Example for ascertaining true ground location and determining positional error for large multi-building parcels and single/ multi- family home (i. e. duplexes and triple-deckers ). a. Example of a large multi-building parcel with both senior and affordable housing units comprised of 15 different parcels, b. Three different addresses have been geocoded to both street-networks (red triangles & orange hexagons) and parcels (yellow squares), c. Building location with unit layouts are georeferenced in ArcGIS using ortho-photos to ascertain true location (green circles), d. Distance between Street-network, parcel and the corresponding true ground location determined through building and unit master plans for large multi-building parcels, e. Distance between Street-network, parcel and the corresponding ortho-photo corrected to the middle of the home for large multi-building parcels.
