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.
The Somerset County Recreation and Open Space Inventory (ROSI) identifies all County owned land (fee and easement) held for public recreation and conservation of natural resources. The land is acquired with funding from the Somerset County Open Space Preservation Trust Fund and NJDEP Green Acres funding. Once placed on the ROSI, no land may be diverted or disposed of for any purpose other than public recreation or conservation of natural resources without the approval of the Commissioner of the State House Commission and Somerset County Board of Chosen Freeholders.
The Sea, Lake and Overland Surges from Hurricanes (SLOSH) model is a computerized numerical model developed by the National Weather Service (NWS) to estimate storm surge heights resulting from historical, hypothetical, or predicted hurricanes by taking into account the atmospheric pressure, size, forward speed, and track data. Maximum of Maximum or Maximum of MEOWs (MOM) SLOSH data is used. A MEOW is defined as a Maximum Envelope of Water, which is generated by compositing several hypothetical SLOSH runs, each of which has the same category, forward speed and direction. The MOM is created by compositing MEOWs of the same category hurricane, and plotting the maximum surge for that category.
The SLOSH data is obtained as a shapefile in polygon format. The SLOSH data is then interpolated by a process agreed upon by USACE and NOAA. This process results in a SLOSH grid that can be compared to the elevation grid. Digital elevation data is collected and an elevation surface created. A grid is created that displays the difference in the elevations of the category 4 SLOSH grid and the elevation surface. This file, which is derived from the depth grid, shows inundation depths in the following ranges: 0-3 feet, 3-6 feet, 6-9 feet, greater than 9 feet.
