Description:
Abstract: This data represents a "generalized" version of the 2007 LULC. To improve the performance of the web applications displaying the 2002 land use data, it was necessary to create a new simplified layer that included only the minimum number of polygons and attributes needed to represent the 2002 land use conditions. The 2007 LU/LC data set is the fourth in a series of land use mapping efforts that was begun in 1986. Revisions and additions to the initial baseline layer were done in subsequent years from imagery captured in 1995/97, 2002 and 2007. This present 2007 update was created by comparing the 2002 LU/LC layer from NJ DEP's Geographical Information Systems (GIS) database to 2007 color infrared (CIR) imagery and delineating and coding 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 2007 land use directly to the base data layer. All 2002 LU/LC polygons and attribute fields remain in this data set, so change analysis for the period 2002-2007 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 2007. Minimum mapping unit (MMU) is 1 acre. ADVISORY: This metadata file contains information for the 2007Land 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. 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 2007 LU/LC in land use analyses 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 data set. The NJDEP may change the line work or polygon coding based on more in depth analysis and field inspection.
Supplemental Information: Several supplemental documents are available that detail the procedures used to create this update and the previous updates done in 1986, 1995 and 2002. Users of any of these data sets may find it helpful to review these documents before using the data. Each update, including this 2007 data set, is created by editing the previous version, so an understanding of any procedures used in the previous updates may be helpful in interpreting the present version. A detailed discussion of specific procedures used to create this updated data set is included in https://www.nj.gov/dep/gis/digidownload/metadata/lulc07/update.html General comments on previous updates are included in https://www.nj.gov/dep/gis/digidownload/metadata/lulc07/lureadme.html Note that the original 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. The specific process used to develop the original ITUM data set is discussed in https://www.nj.gov/dep/gis/digidownload/metadata/lulc07/itum.html. The process used to integrate the ITUM LU/LC and FWW coverages into one theme, including a discussion of the Upper Wetlands Boundary (UWB) line in the process, is discussed in detail in the https://www.nj.gov/dep/gis/digidownload/metadata/lulc07/fwwinteg.html Also note that 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. These hydrologic boundaries were replaced during the 2002 update with boundaries mapped from the 2002 imagery. A description of the land use codes used in this data set is given in https://www.nj.gov/dep/gis/digidownload/metadata/lulc07/anderson2007.html This document is edited version of 'A Land Use and Land Cover Classification System for Use with Remote Sensor Data', U. S. Geological Survey Professional Paper 964, 1976. The COWARDIN86 and CLASS86 codes used to describe the non-tidal wetlands are codes generated during the original FWW mapping program. CLASS86 is a numeric code that represents each of the specific COWARDIN86 descriptive codes which follow the U.S. Fish and Wildlife Cowardin Classification System, (with some modifications specific to the New Jersey program). These two codes have been retained in all subsequent land use updates to identify those wetland polygons that were originally mapped as part of that FWW mapping program. Wetland polygons existing in the land use layers, including the 2007 update, which have the COWARDIN86 field valued as NULL, and CLASS86 code of 0 were mapped as part of the land use mapping efforts and not the FWW mapping effort. Note also that the COWARDIIN86 values have not been updated since the original mapping, although the wetland Anderson classification land use code may have been changed to reflect a change in the wetland polygon composition. This position was followed because it was felt that with the level of field work used in developing the 2007 data, it would be difficult to assign new Cowardin classes to the modified wetlands data with the same level of detail possible with the original FWW wetlands mapping. Note also that these attributes were named CLASS and COWARDIN in previous land use updates. They were renamed for this effort to CLASS86 and COWARDIN86 to indicate that the values in these fields do reflect wetland polygon classification from the original FWW mapping based on the 1986 photography.

Process Date: 20100701
Process Step:
Process Description: 
The 2002 land use/land cover data set was displayed over 2007 CIR digital imagery. New line work and codes needed to describe the land use conditions interpreted from the 2007 imagery were added directly to the 2002 layer through interactive editing. Photo-interpretation, interactive editing, field surveys and initial QA/QC done by Aerial Information Systems, Redlands, CA, under the direction of the NJDEP/BGIS. The baseline 2002 data sets edited in this project were prepared by NJDEP/BGIS, from the original 2002 Land Use/Land Cover Update layers. The original layers included both 2002 and 1995 land use codes and linework. The 1995 codes and linework were removed by dissolving on the critical 2002 land use attributes. This produced layers that included only the 2002 codes and linework. It was these dissolved layers that were edited in this present project . Final QA/QC and final data set formatting for the 2007 update layers was done by NJDEP/BGIS. Land use/land cover in 2007 was captured by adding additional line work and codes to the base layer, and filling in specific attribute fields that describe the 2007 land use/land cover ground conditions. All 2002 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. The 2002 polygons and codes were updated if it was felt that original mapped lines or land use classifications of any 2002 polygon needed to be modified based on the better 2007 imagery. 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. Data sets were processed and delivered by Watershed Management Area (WMA). Note that the boundaries for two WMAs, 5 and 7, underwent major modifications between the time the 2002 and 2007 land use projects were undertaken, with a large portion of the former WMA7 now included as part of WMA5. The data for the present 2007 update reflects the new boundaries for these two management areas.
