Description: The Area Parcel Feature Classes are defined and delivered as two separate feature classes:
Residential Parcel Boundaries and Non-Residential Parcel Boundaries. The taxonomy of these individual feature classes are based on the standardization of CoreLogic’s Property Indicator and Land Use attributions.
The logical breakout of the Residential vs. Non-Residential Parcels is fundamentally defined by Property Indicator or a Land Use Code based on ownership and not on dwelling.
For example; a record with a Property Indicator or Land Use Code that has an entry of Single Family Residence (SFR), or Mobile Home, will be delivered within the Residential Feature Class because of the ownership of the parcel or structure.
In contrast to this; a record with a Property Indicator or Land Use Code of Nursing Homes or Apartment Complex, will be delivered within the Non-Residential Feature Class because of the commercial ownership of the parcel or structure.
The source of this GIS data is derived from county map, tax, and deed files. The completeness of the data is based on county reporting practices. Not all counties report data attributes in the same fashion, therefore some GIS attribution may also be unavailable.
Land Use note:
This is a CoreLogic derived field that standardizes and classifies all U.S. parcel data according to permitted land use. CoreLogic’s standardization logic relies on the Assessor’s determination of land use, or the state land use if county land use is not available, as well as proprietary logic. If neither the county or state land use is available, CoreLogic standardized code for a given parcel may be null. At the highest level property and parcels are classified as Residential (1-4 dwelling units in a single structure) and Non-Residential (all other property and parcel types). CoreLogic further classifies Residential Land Use into a range of distinct values denoting, for example, a single family residence, a cabin, or a townhouse. Similarly, Non-Residential parcels are classified into land Use codes such as Hotel, Retail, Industrial, Agricultural, Vacant and Tax Exempt (government).
Through CoreLogic’s patented processes and technology, our team integrates and standardizes this wide array of content, into a single GIS product.
Standardization note:
In order to standardize representation across the nationwide data set, all features are single-part, with each record in the attribute table corresponding to a single polygon feature. Therefore, some parcels, such as those which are noncontiguous, are represented by more than one polygon. Property characteristic attribute values are duplicated on polygons which are part of the same parcel. For analysis of property characteristics, a parcel can be identified by unique APN and APN2 values. Records corresponding to the same parcel should be treated as a set to avoid inaccuracies with attribute duplication.
Note that topological issues may exist in the data set, such as overlaps or gaps between features. All features have passed the ArcGIS Check Geometry test.
