Description: This polygon layer was created from the flash_usgs_florida_arc data layer. Polygons were created based on continuous contour lines that cover the entire Florida shelf only, "island" contours were not included in this polygon layer. This metadata provides details on the cartographic production methods developed for digital map files and habitat data used in the United States Geological Survey (USGS) Florida Shelf Habitat Map Project. FLaSH Map was initiated in 2006 to accomplish goals set for USGS Coastal and Marine Geology National Benthic Habitat studies. In many instances, existing data were reformatted for use with Web-based technologies and user-friendly visualization tools implemented by FLaSH Map. In these instances, the metadata file explains the steps taken to incorporate the data set into the larger body of work. Data sets were pre-processed for use in a Geographic Information System (GIS) geo-database, and for visualization in one of several Web-based tools: an Internet Map Service (IMS), an interactive .html, or a .kml format for use in a global viewer such as World Wind or Google Earth. The Florida shelf bathymetry data are derived from the National Oceanic and Atmospheric Administration's (NOAA) Electronic Navigational Charts and from the National Geospatial-Intelligence Agency's (NGA) The Digital Nautical Chart®.
