Description:
Abstract:
This data set represents a combination of Rutgers University New Jersey 1995 Level 3 Land Cover (NJ L3LC) Classification wetland, New Jersey Department of Environmental Protection (NJ DEP) wetland dataset, and NJ DEP Tideland dataset. We used NJL3LC for most of the state and NJ DEP wetland data and NJ DEP Tideland data only in Delaware River upstream of Delaware Memorial Bridge. We classified wetlands into tidal open water, tidal wetland, non-tidal open water, non-tidal wetland, and dry land based on their original classifications. For further details on which areas use NWI and DNR, please see J.G. Titus and J. Wang 2008 report "Maps of lands close to sea level along the middle Atlantic coast of the United States " included in the zip file associated with this data set.
The zip file associated with this data set should include:

1.README_NJ_Elevation.doc, which provides a brief overview of the relationship between this dataset and related data.

2. Classification_of_Coastal_Wetlands.doc
Purpose:
1.  To be used along with the outside-of-study-area (nj_out_of_study_area.shp) as an overlay to the New Jersey sea level rise planning study's shore protection scenario data set, either for creating for maps or calculating statistics.  The sea level rise planning study examined  only land that is either below the 20-ft contour or within 1,000 feet of the shore. Any shore protection attribute values for  lands that are either  wetlands, open water, or land above the 20 ft NGVD contour may be misleading or wrong, and have not been reviewed. Therefore, some sort of "wetland mask" and "out of study area mask" must always be used with the New Jersey shore protection data set.

2. To be used along with the New Jersey Digital Elevation Model (DEM) to display wetlands and water in elevation maps of lands close to sea level.  The DEM provides "no data" (-9999) for all cells that are either open water or tidal wetlands.

Attribute_Accuracy_Report:
The underlying data used in the creation of this layer may contain errors or omissions. 
Attribute errors may have resulted from errors in the creation of the underlying NJ L3LC and NJ DEP Tideland and Wetland(NWI) data, or from how we classified the various types of wetlands.

Errors in Underlying Data.   Common errors in the underlying NJ L3LC and NJ DEP Tideland and Wetland data include changes since the imagery was collected, including:

a. Rising sea level may have converted dry land to tidal wetlands 

b. Rising sea level and other processes may have eroded dry land or tidal wetlands, converting it to open water

c. Nontidal wetlands may have been drained or filled for development.
In addition,  the NJ L3LC  dataset does not differentiate tidal river from non-tidal river. We only corrected this problem in Delaware and Hudson Rivers, but ignored the other smaller rivers.

Process_Description:
I. All areas other than the Delaware River upstream of Delaware Memorial Bridge and Hudson River. 

We classified the Rutgers University New Jersey 1995 Level 3 Land Cover (NJ L3LC) wetlands  into tidal open water, tidal wetland, non-tidal open water, non-tidal wetland, and dry land.  

1). Our tidal Open Water consists of the Rutgers'  Marine/Estuarine Open Water.

2). Our tidal Wetlands consists of Rutgers'  Marine/Estuarine Unconsolidated Shore, Estuarine Emergent Marsh, and Brackish Tidal/Fresh Tidal Marsh.

3). Our Non-Tidal Open Water consists of Rutgers' Riverine/Lacustrine/Palustrine Open water.

4). Our Non-Tidal Wetlands consists of Rutgers' Riverine/Lacustrine/Palustrine Unconsolidated Shore, Riverine/Lacustrine/Palustrine Emergent Marsh, Wetland Forest, and Wetland Scrub/Shrub

5). We treat all other attributes as  dry land.

II. Delaware River upstream of Delaware Memorial Bridge and Hudson River. 

The NJ L3LC dataset does not differentiate between tidal riverine and  non-tidal riverine.  Therefore, we used a combination of NJ DEP wetland and NJ DEP Tideland data to replace it in Delaware River upstream of Delaware Memorial Bridge and Hudson River. The NJDEP wetland dataset is a polygon dataset which includes tidal wetland, but not tidal open water. So we used NJDEP wetland dataset to define tidal wetland. The NJ DEP Tideland dataset is a line coverage which represents the upper limit of tidal influences. So we classified all the area on the river side of this line as tidal open water, except tidal wetlands defined by NJDEP wetland dataset.
