The U.S. Pacific West Coast Internet Map Server contains published data layers and information from the U.S. Geological Survey, Coastal and Marine Geology Program. An example of the default map view is shown at the right. The most striking data layer is the 250 m resolution digital mosaic of the GLORIA (Geologic Long-Range Inclined Asdic) sidescan data collected in the Exclusive Economic Zone (EEZ) of the U.S. West Coast. These data were acquired during a major field study conducted in 1984. A data layer indicating the Coastal Vulnerability Index showing the potential of coastal change due to sea-level rise is also available.

In addition to the GLORIA sidescan data, some multibeam backscatter and shaded relief imagery collected during various coastal mapping surveys are also available for viewing. Locations of these surveys are available and are shown in the default mapview. Other basemap data layers relative to the specific mapsite have been compiled from a variety of public domain sites and are also available for viewing and download.

Within the Internet Map Server, data layers have been grouped within category headings. Clicking the appropriate data folder will expand or collapse the folder allowing the individual data layers to be displayed. Data layers may be "turned-off or on" by selecting the visible button beside the layer name. The map view will automatically update. A complete description of the available data layers and links to download the data may be found in the GIS Data Catalog.
