National Wetlands Inventory for New Jersey 2009

This data set represents the extent, approximate location and type of wetlands and deepwater habitats in the conterminous United States. These data delineate the areal extent of wetlands and surface waters as defined by Cowardin et al. (1979). Certain wetland habitats are excluded from the National mapping program because of the limitations of aerial imagery as the primary data source used to detect wetlands. These habitats include seagrasses or submerged aquatic vegetation that are found in the intertidal and subtidal zones of estuaries and near shore coastal waters. Some deepwater reef communities (coral or tuberficid worm reefs) have also been excluded from the inventory. These habitats, because of their depth, go undetected by aerial imagery. By policy, the Service also excludes certain types of \"farmed wetlands\" as may be defined by the Food Security Act or that do not coincide with the Cowardin et al. definition. Contact the Service's Regional Wetland Coordinator for additional information on what types of farmed wetlands are included on wetland maps. This data is hosted at, and may be downloaded or accessed from PASDA, the Pennsylvania Spatial Data Access Geospatial Data Clearinghouse http://www.pasda.psu.edu/uci/DataSummary.aspx?dataset=1455本数据集呈现了美国本土范围内湿地与深水生境的分布范围、大致位置及类型。这些数据依据Cowardin等人（1979年）提出的定义，划定了湿地与地表水的面积范围。 由于以航空影像作为湿地检测的主要数据源存在局限性，部分湿地生境未纳入本次国家制图项目。此类生境包括分布于河口潮间带、潮下带及近岸沿海水域的海草或沉水水生植被。部分深水礁群落（珊瑚或管栖蠕虫礁）也未纳入本普查范围，这类生境因所处水深较大，无法通过航空影像被探测到。 该机构还依据政策排除部分"人工养殖湿地"，此类湿地可由《食品安全法案》（Food Security Act）定义，或不符合Cowardin等人提出的湿地定义。如需了解湿地地图中包含的人工养殖湿地类型详情，请联系该机构的区域湿地协调员。 本数据集托管于宾夕法尼亚空间数据获取地理空间数据交换中心（PASDA, Pennsylvania Spatial Data Access Geospatial Data Clearinghouse），可通过以下链接下载或访问：http://www.pasda.psu.edu/uci/DataSummary.aspx?dataset=1455
