The U.S. Atlantic East Coast Web Mapping Application contains published data layers and information from the U.S. Geological Survey, Coastal and Marine Geology Program (CMGP). An example of the default map view is shown at the right. This map view shows the U.S. Atlantic East Coast, portions of Canada and the Caribbean, the U.S. Atlantic East Coast GLORIA mosaic at a 250 m resolution and the Coastal Vulnerability Index showing the potential of coastal change due to sea-level rise. 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. East Coast. These data were acquired during a major field study conducted in 1987. A data layer showing the location of other CMGP seafloor mapping surveys is also available.

In addition to the GLORIA sidescan data, location of surficial samples and bottom photographs are also available for viewing. 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 Web Mapping Application, 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.

Internet Map Server hyperlink tool icon Hyperlink properties

The data layers listed below have associated hyperlink properties. To see the associated hyperlink property use the "Search" tool from the "Tools" drop down menu. From the "Search" window select the layer you wish to search on and then select one of the graphical tools to select geometric feature(s). On the MAP use the mouse to select the feature(s) you are interested in and the results will be displayed in the Search window. Selecting the hyperlink image icon, web mapping application hyperlink tool icon, will result in the associated information being displayed in a new browser window.

  • 1960 CONMAP bottom photos - When the "Search" tool is used on this layer the results will have a hyperlink icon to select, to view the bottom photographs acquired as part of the ground-truth topography. These photographs, collected during the 1960's as part of the USGS Continental Margin Program, have been rescued and georeferenced with an approximate spatial location.
