Description:
Abstract:
ADVISORY: This metadata file contains information for the 2002 Land Use/Land Cover (LU/LC) data sets, which were mapped by Watershed Management Area (WMA). There are additional reference documents listed in this file under Supplemental Information which should also be examined by users of these data sets.

The 2002 LU/LC was created by comparing the 1995/97 LU/LC layer from NJ DEP's geographical information systems (GIS) database to 2002 color infrared (CIR) imagery and delineating areas of change. Work for this data set was done by Aerial Information Systems, Inc., Redlands, CA, under direction of the New Jersey Department of Environmental Protection (NJDEP), Bureau of Geographic Information System (BGIS). LU/LC changes were captured by adding new line work and attribute data for the 2002 land use directly to the base data layer. All 1986 LU/LC polygons and attribute fields were removed from this update, however, all 1995/97 LU/LC polygons remain in this data set, so change analysis can be undertaken from this one layer. The classification system used was a modified Anderson et al., 2002 classification system. An impervious surface (IS) code was also assigned to each LU/LC polygon based on the percentage of impervious surface within each polygon as of 2002 and 1995/97. Minimum mapping unit (MMU) is 1 acre.

As stated in this metadata record's Use Constraints section, NJDEP makes no representations of any kind, including, but not limited to, the warranties of merchantability or fitness for a particular use, nor are any such warranties to be implied with respect to the digital data layers furnished hereunder. NJDEP assumes no responsibility to maintain them in any manner or form. By downloading this data, user agrees to the data use constraints listed within this metadata record.

Purpose:
The data set will provide information for regulators, planners, and others interested in LU/LC changes, and allow them to quantify those changes over time using GIS.

The use of the updated 2002 LU/LC and IS layer in change analyses studies will provide a means of monitoring "the health of the citizens and ecosystems of New Jersey" through the use of diverse applications.

This data set is intended to serve as a resource for analysis rather than regulatory delineations. The NJDEP may change the line work based on more in depth analysis and field inspection for regulatory purposes.

Supplemental_Information:
A detailed discussion of specific procedures used to create this updated data set will not be available until the project is complete statewide. General comments on previous updates is included in LUREADME.DOC. Users of this data are strongly urged to review these documents, as well as others included below, before using the data set. The 1986 baseline data layer was composed of two originally separate layers; the LU/LC from the Integrated Terrain Unit Mapping (ITUM) project and the Freshwater Wetlands (FWW) data from the New Jersey Freshwater Wetlands Mapping Project. NJDEP integrated the two themes into one coverage in 1996. Included in the baseline LU/LC data set, as part of the original land use layer from the ITUM mapping, were the statewide hydrology boundaries for areas below the Upper Wetlands Boundary (UWB) line. The specific process used to develop the original ITUM data set is discussed in ITUM.DOC. The process used to integrate the ITUM LU/LC and FWW coverages into one theme, including a discussion of the UWB in the process, is discussed in detail in the FWWINTEG.DOC. A list of land use codes in given in CODELIST2002.DOC, with a full description of each code given in ANDERSON2002.DOC. The Cowardin codes used to describe the non-tidal wetlands are discussed in FWW.DOC. All documents are available in HTML format as follows:

Digital images were created from 1:40000 scale NAPP CIR images by USGS, referenced in UTM, NAD83. These images were then projected to New Jersey State Plane Feet Coordinates (NJSPF), NAD83, and compressed to JPEG images files. These NJSPF compressed files were used in the development of the this data set. The original images in UTM are available from the USGS website. The NJSPF versions are available from the NJDEP site. Both sites have online and CD distribution of these images.

Land use/land cover for 1995/97 was digitized directly from 1995/97 digital image files. Photographic transparencies of the CIR images used to create the digital files were also viewed stereoscopically to aid in land use/land cover determinations.
Process_Step:
Process_Description:
Baseline 1995/97 land use/land cover data set was displayed over 2002 CIR digital imagery. Photointerpretation, interactive editing, field surveys and initial QA/QC done by Aerial Information Systems, Redlands, CA, under the direction of the NJDEP/BGIS. The baseline data sets were produced by NJDEP/BGIS. Final QA/QC and final data set formatting done by NJDEP/BGIS. Land use/land cover in 2002 was captured by adding additional line work and codes to the base layer, and filling in specific attribute fields that describe the 2002 land use/land cover. All 1995/97 codes and line work remain in the data set so that change analysis can be performed on all polygons using this one updated data set. These polygons and codes were updated if the lines were spatially incorrect or clarity of the better imagery helped interpret the condition in 1995. In addition to the lu/lc codes, an impervious surface estimate was made for every polygon. This was a visual estimate and not a measured value. While the actual line and code edits were done directly through the AV application, photo transparencies of all imagery were available for stereoscopic analysis to aid interpretation. Modifications were also made to the baseline data layer during the update process to account for discrepancies due to quality of the 1986 or 1995/97 base maps. Except for the FWW cowardin codes, 1986 codes were removed from this update. Data sets were processed and delivered by Watershed Management Area (WMA).
