The areas on the map are linked to the corresponding data sets which contain values for X (easting), Y (northing), Z (elevation), and the RMS set to 0.0. Purpose: Detailed, high-resolution maps of Florida Bay mudbank elevations are needed to understand sediment dynamics and provide input into water quality and circulation models. The bathymetry of Florida Bay has not been systematically mapped in nearly 100 years, and some shallow areas of the bay have never been mapped. Numerical circulation and sediment transport models being developed for the South Florida Ecosystem Restoration Program are being used to address water quality issues in Florida Bay. Digitizing the historical shoreline and bathymetric data for comparison with modern data provides information on sedimentation rates within the Bay.

Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: For data format consistencies, RMS values for the 1890's data set are equal to 0.0. The horizontal positions of each data point were transformed from Latitude/Longitude to UTM (Zone 17) XY coordinates using NOAA/NGS software UTMSv1.0. Quantitative_Horizontal_Positional_Accuracy_Assessment: Horizontal_Positional_Accuracy_Value: 0.05 Horizontal_Positional_Accuracy_Explanation: unavailable Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: For data format consistencies, RMS values for the 1890's data set are equal to 0.0. Vertical positions were referenced to MLW (Mean Low Water). According to NOAA tidal datum information, NAVD88 is approximately 0.41m (1.35 ft) above MLW in the Florida Bay area. The 1.35 feet average is calculated using the elevation information from several tidal benchmarks throughout the Florida Keys. These tidal benchmarks are published by the National Geodetic Survey and can be located on their website http://www.ngs.noaa.gov/cgi-bin/ngs_opsd.prl/. Five tidal benchmarks were chosen from four different U.S. Geological Quadrangle locations including Blackwater Sound, Plantation Key, Long Key and Grassy Key. To compare the 1890's values to NAVD88 add 1.35 ft. to the depth values. Lineage: Process_Step: Process_Description: The historical bathymetric data obtained form NOAA/NOS archives were digitized using an Altech Digitizer. The data was georeferenced from the digitizer coordinates to geographic coordinates (latitude and longitude) using archived NGS control points on NAD 83.
