Item Identification

Title: Coastal Wetlands
Short Name: CoastalWetlands
Status: Completed
Publication Date: 2017-12-14
Abstract:

This data set represents the extent, approximate location and type of estuarine and marine wetland habitats in the United States and its Territories. These data delineate the areal extent of wetlands and surface waters as defined by the National Wetland Inventory (NWI) and includes the equivalent Coastal and Marine Ecological Classification Standard (CMECS) units. Certain wetland habitats are excluded from the NWI program because of the limitations of aerial imagery as the primary data source used to detect wetlands. This data set is neither designed nor intended to represent legal or regulatory products. For wetland information visit www.fws.gov/wetlands/.

Purpose:

To support coastal and ocean planning and other activities pursuant to the Energy Policy Act, Coastal Zone Management Act, Magnuson-Stevens Fishery Conservation and Management Act, National Environmental Policy Act, Rivers and Harbors Act and the Submerged Lands Act.

Supplemental Information:

The native coordinate system for this layer is Geographic Coordinate System North American 1983 (NAD 83).

Process Steps

Process Step 1

CC ID: 698216
Description:

Go to https://www.fws.gov/wetlands/Data/State-Downloads.html and download all geodatabase zip files

Unzip files and in each geodatabase, add the _Wetlands feature class to ArcMap

For each, Select by Attributes where WETLAND_TYPE = Estuarine and Marine Wetland and export into a new feature class

Merge the exported feature classes into a single feature class

Union the single feature class and Intersect to find overlapping features

Delete/Merge any overlapping features based on state and ATTRIBUTE

Crosswalk CMECS info into attribute field using table found at https://www.fws.gov/wetlands/documents/NWI_Wetlands_and_Deepwater_Map_Code_Diagram.pdf

Delete all superfluous fields

Check geometry and project data into WGS 1984 Auxiliary Sphere
