Description:

Abstract:
This data was created by comparing the 1986 land use/land cover (LU/LC) layer from NJ DEP’s geographical information systems (GIS) database to 1995/97 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 and Analysis (BGIA). LU/LC changes were captured by adding new line work and attribute data for the 1995/97 land use directly to the base data layer. All 1986 LU/LC polygons and attribute fields remain in this data set, so that change analysis can be undertaken from this one layer. The classification system used was a modified Anderson et al., 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 1995/97. Minimum mapping unit (MMU) is 1 acre.
Purpose:
The dataset 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 1995/97 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 is included in UPDATE.DOC, with general comments 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 CODELIST.DOC, with a full description of each code given in ANDERSON.DOC. The Cowardin codes used to describe the non-tidal wetlands are discussed in FWW.DOC.

Process Step:

Process Description:
Baseline 1986 land use/land cover data set was displayed over 1995/97 digital imagery in a special ArcView application designed especially to perform these land use updates. Photointerpretation, interactive editing, field surveys and initial QA/QC done by Aerial Information Systems, Redlands, CA, under the direction of the NJDEP/BGIA. The baseline data sets were produced by NJDEP/BGIA. Final QA/QC and final data set formatting done by NJDEP/BGIA. Land use/land cover in 1995/97 was captured by adding additional linework and codes to the base layer, and filling in specific attribute fields that describe the 1995/97 land use/land cover. All 1986 codes and linework remain in the data set so that change analysis can be performed on all polygons using this one updated data set. In addtion 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 done to the baseline data layer during the update process to account for discrepancies due to quality of the 1986 base maps. 1986 codes were also modified to reflect expanded classification system and reduced Minimum Mapping Unit (MMU). Data sets were processed and delivered by Watershed Mangement Area (WMA). These boundaries changed between the start and completion of this project. Preparation of final data sets involved re-tiling by new WMA boundaries.
