The purpose of the data is to support Florida Keys National Marine Sanctuary (FKNMS) benthic habitat mapping and research planning efforts for improved spatial and fishery ecosystem management. The data consists of multibeam data sets that for this segment were collected by eTrac Inc., under contract to NOAA/OCS in 2018.
All data products produced are supplied as ready to use products for a Geographic Information System (GIS) and CARIS, projected in Universal Transverse Mercator (UTM) 17 N, North American Datum 1983 (NAD83) and vertically reduced to Mean Lower Low Water (MLLW). |
