Item Identification

Title: Coastal Wetlands
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 ocean planning activities pursuant to the Executive Order Regarding the Ocean Policy to Advance the Economic, Security, and Environmental Interests of the United States, the Energy Policy Act, the National Environmental Policy Act, the Rivers and Harbors Act, and the Coastal Zone Management Act.

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
