Title
Wetlands of New Jersey (from Land Use/Land Cover Update) [New Jersey] {2002}
Description
The wetlands polygons included in this data set are extracted from the Land Use 2002 layer. Displayed are all polygons that have a TYPE02 code of 'WETLANDS'. While these wetland delineations are not regulatory lines, they represent important resource data in identifying potential wetland areas. These wetland data have a somewhat involved delineation history. Non-tidal wetlands were first mapped in a separate effort under the Freshwater Wetlands Mapping Program (FWW), based on 1986 photography. Although the original FWW maps were produced as a separate data set, they were incorporated into a state wide composite land use/land cover (LU/LC) data set also being initially mapped from the 1986 photography. The FWW delineations were integrated into the LU/LC data layer in their entirety as originally delineated, with all line work and coding intact. The tidal wetlands were being mapped as part the LU/LC mapping effort itself. This integrated data set, including the FWW delineations, and the remaining land use/land cover delineations for areas outside of the FWW polygons, which included tidal wetland areas, became the initial 1986 LU/LC layer for the NJDEP. Beginning in 1995, NJDEP acquired new aerial imagery, and began updating the initial integrated LU/LC layer from 1986 based on this newer imagery. The 1986 layer was examined with the new imagery, and areas of change delineated, with any new line work and land use codes needed to map the changes added to the base data set. This updated LU/LC layer is identified as Land Use 1995 in this application. Included in the change analysis were any non-tidal wetland polygons mapped in the original FWW mapping effort, as well as any tidal wetland polygons mapped in the 1986 LU/LC mapping effort. More recently, new photography was acquired in the spring of 2002, and this photography was used in a second land use update project. The Land Use 1995 layer was examined over the 2002 imagery, and an updated layer based on the 2002 imagery was created, available in this application as 'Land Use 2002'. The layer displayed here is the selection of all wetlands, both tidal and non-tidal, as included in that 2002 land use layer. As with all original wetland delineations delineations, this data set is intended to serve as a resource for analysis rather than regulatory delineations. The NJDEP may change the line work of any wetlands polygon based on more in depth analysis and field inspection for regulatory purposes.
