The catalog section of the Wisconsin Coastal Atlas provides several paths to discover, assess, and download geospatial data for the Great Lakes coasts of Wisconsin. Catalog resources include Open Geoportal - a map-based interface to search, preview and download geospatial data; GeoNetwork - an interoperable geospatial metadata catalog; a simple data download matrix inspired by the open data catalog at the City of Vancouver, BC; and links to a variety of state, regional and national geospatial catalogs.


WCA Coastal Data Access Matrix

The WCA Coastal Data Access Matrix encourages data sharing by providing access to coastal geospatial data hosted by Wisconsin Sea Grant in several formats including Esri shapefiles and Google Earth KML files. Click on links in the matrix cells to download data. Documentation is available by clicking the metadata cell.

WCA Open Geoportal

This data search interface for the Wisconsin Coastal Atlas utilizes Open Geoportal -- software developed by a consortium led by Tufts University. Open Geoportal provides organizations the opportunity to share geospatial data layers, maps, metadata, and development resources through a common interface.
