Description: This point feature class represents the center (not the true centroid) of each tax parcel polygon. The site address information is associated with each point that has a site address. Every point has a PIN (Parcel Identification Number) value. If there are multiple PINS associated with a particular tax parcel, the points are stacked on top of each other. If there are multiple site addresses associated with one PIN, these are stacked on top of each other as well. The points were created by a process that located the approximate center from the polygon feature class.
Description: A spatial representation of a subset of parcel features that contain special use characteristics. This polygon feature class is maintained in a geodatabase using topology with the TaxParcel feature class. The key attribute is AccessType, which describes the type of access (Prescriptive, Dedicated, or Private) on the feature.
Description: A spatial representation of subdivision blocks. This polygon feature class is maintained using topology with other LandManagement data layers.
Description: The building outline polygons were derived from the 2017 imagery by Eagleview. They contain both a KeyPIN field, which can be used to link parcel information to the data, and a Status field (existing, changed, new). The Status field was created based on Eagleview's comparison against 2010 the County's 2010 footprints (originally created by SEMCOG). The data was updated on January, 2019, per ad hoc request.
Description: The parcel boundaries are a line feature class that represent every line that may be used to comprise a lot or tax parcel. They are constructed from subdivision plats, condominium master deeds and their amendments, recorded and unrecorded surveys, and legal descriptions found within deeds. If public or private roads are noted on source documents, they are compiled, regardless of width. Any legal description that creates a division of land, recorded or unrecorded, must be approved by the local authority and submitted to the Equalization Division for permitting or taxation purposes. Most of the boundary information is complied using coordinate geometry (COGO) based on geodetic control tied to the Public Land Survey System (PLSS) corner monuments. In some cases, boundaries are captured from features shown on digital orthophotography, such as shorelines. Other boundaries that cannot be constructed from coodinate geometry have been digitized from hard copy sources. The original parcel boundaries were converted from two CAD fomats. Novi, Wixom, Rochester Hills, Rochester, Ferndale, Highland, and Waterford were converted from Genamap. The remainder of the County was converted from Microstation. In April, 2005, the lines were migrated into an ArcSDE versioned geodatabase editing environment.
