This GIS data set represents coral and hardbottom habitats off Broward, Miami-Dade and Palm Beach Counties Florida. These data are the results of an integrated mapping project undertaken to provide a habitat map of the shallow Broward County seafloor between the 0m and 35m contour. All data were mapped in ArcGIS9 and polygons were drawn at a scale of 1:6000 with a one acre minimum mapping unit. The entire area mapped was roughly 110 square-kilometers. For the production of these polygons, high resolution LADS bathymetry was used to map reef geomorphology, acoustic data (QTC and Echoplus) were used to aid in defining the geomorphologic features into habitat types, and a waterproof drop video camera from a boat was used as groundtruthing to confirm substrate type. The shallow inshore seafloor from the 0m to -6m contour was mapped using a combination of assimilated data types including aerial photography and high-resolution bathymetry and the deeper seafloor habitats, from the -6m to the -35m contour, were mapped using mostly high-resolution bathymetry and acoustic ground discrimination. The result produced a seamless GIS benthic habitat classification of the entire nearshore reef system in Broward County. Refer to the final project report: Development of GIS Maps for Southeast Florida Coral Reefs, for a complete description of the classification.
