Hundreds of GIS layers are freely available on NOAA's Pacific Northwest Environmental Response Management Application® (ERMA) mapping site, published by the NOAA Office of Response and Restoration. The Puget Sound Institute is collaborating with NOAA to add map layers and GIS data to Pacific Northwest ERMA®. The goal is to map Puget Sound and Salish Sea ecosystem data, analysis and research.
In ERMA®, you can search and visualize multiple map layers, view metadata, display attributes, query, zoom, print, and download GIS data. All in your web browser—with no additional software required. It's an effective tool for finding and browsing GIS information relevant to the Puget Sound region.
