Downloadable Wetland Shapefiles

This report contains Geographic Information System (GIS) data in georeferenced vector (polygon) format. The vector (polygon) data are available as Environmental Systems Research Institute (ESRI) shapefile files. Shapefiles generally include *.shp, *.shx, *.xml, and *.dbf files at a minimum. All these data also include *.prj files which contain the dataset projection information. The GIS shapefiles have been bundled with their corresponding Federal Geographic Data Committee (FGDC)-compliant metadata into compressed zip files.

To download the data, right-click on the appropriate filename hotlink below. Then select 'Save Target As...' to save the file to your local hard drive.

The following products were created in the course of this study:

1. GIS datasets (shapefile format) of NWI polygons in the Yaquina and Alsea estuaries, containing recommended revisions to the NWI classification (Yaquina_tidal_NWI_2011.zip and Alsea_tidal_NWI_2011.zip, respectively). Datasets include metadata, based on the metadata provided by EPA for the original Yaquina NWI layer.
2. GIS datasets (shapefile format) of the prioritization sites identified in the 1999 prioritization of tidal wetlands in the Yaquina and Alsea estuaries (Brophy, 1999): Yaquina_tidal_wetlands_2011.zip for the Yaquina estuary, and Alsea_tidal_wetlands_2011.zip for the Alsea estuary. Attribute tables contain all publicly available data in the original site information tables, as well as updates from this project. Metadata are included with the shapefiles.
