The statewide composite of parcels (cadastral) data for New Jersey was developed during the Parcels Normalization Project in 2008-2014 by the NJ Office of Information Technology, Office of GIS (NJOGIS). The normalized parcels data are compatible with the New Jersey Department of Treasury MOD-IV system currently used by Tax Assessors and have been joined with the parcels in this dataset. This composite of parcels data serves as one of New Jersey's framework GIS data sets. Stewardship and maintenance of the data will continue to be the purview of county and municipal governments, but the statewide composite will be maintained by OGIS.

Parcel attributes were normalized to a standard structure, specified in the New Jersey GIS Parcel Mapping Standard, to store parcel information and provide a PIN (parcel identification number) field common to the PIN stored in the PAMS database. The standard is available for viewing and download at http://njgin.nj.gov/NJParcelStandards/NJGISParcelMappingStandard.pdf. The PIN also can be constructed from attributes available in the MOD-IV Tax List Search table (see below). Attributes in this feature class table include parcel attributes specified in the New Jersey GIS Parcel Mapping Standard, available for download at http://njgin.nj.gov/NJParcelStandards/NJGISParcelMappingStandard.pdf. Additional attributes include a large sub-set of information from matched MOD-IV records as published for public use by NJ Department of the Treasury, Division of Taxation.

The polygons delineated in the dataset do not represent legal boundaries and should not be used to provide a legal determination of land ownership. Parcels are not survey data and should not be used as such. Please note that these parcel data sets are not intended for use as tax maps. They are intended to provide reasonable representations of parcel boundaries for planning and other purposes.

The statewide MOD-IV table is available as a separate download "Real Estate MOD-IV Tax List Search Plus Database of New Jersey". Statewide parcels are also available as a separate download "Parcels Composite of New Jersey".

Also available separately are county-wide parcels and tables of property ownership and tax information extracted from the State of New Jersey Division of Taxation MOD-IV data base. A GIS_PIN has been constructed for each record in a manner consistent with the PAMS_PIN definition, in order to provide a join field. Please see Data Quality / Process Steps for details about updates to this composite since its first publication.
