GIS Data Catalog
Below is a list of data available for viewing on the USGS Coastal and Marine Geology Program's USGS Louisiana Continental Slope Internet Map Server. Data have been compiled from a variety of sources and most of the data are currently available on-line for user access and downloads. Though some images have been converted to geographic for compilation within the Internet Map Server (IMS), the published images may be available in a projected coordinate system. The specific projection and datum information of the published image is noted in the data layer description.
