Somerset County Wetlands
<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>The dataset is a spatial representation of wetlands in Somerset County, New Jersey. The wetlands polygons included in this data set are extracted from the Land Use 2012 layer. Displayed are all polygons that have a TYPE12 code of 'WETLANDS'. While these wetland delineations are not regulatory lines, they represent important resource data in identifying potential wetland areas.The 2012 LU/LC data set is the fifth 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, 2007 and 2012.  This present 2012 update was created by comparing the 2007 LU/LC layer from NJDEP's Geographic Information Systems (GIS) database to 2012 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 2012 land use directly to the base data layer.  All 2007 LU/LC polygons and attribute fields remain in this data set, so change analysis for the period 2007-2012 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. This metadata file contains information for the 2012 Land Use/Land Cover (LU/LC) data sets, which were mapped by USGS Subbasin (HU8).   There are additional reference documents listed in this file under Supplemental Information which should also be examined by users of these data sets.
