The purpose of this data is to support Florida Keys National Marine Sanctuary (FKNMS) benthic habitat map products and research planning efforts. We are providing improved seafloor mapping data products for areas of the FKNMS. They have been incorporated into the FKNMS Digital Atlas, an interactive dataviewer established in 2018 that features a number of mapping products, groundtruthing images and videos. The Sanctuary and partners have been using the dataviewer map service for planning, data visualization, and management plan development.
<DIV STYLE="text-align:Left;"><P STYLE="font-size:16ptmargin:0 0 0 0;"><SPAN><SPAN>This layer is a Principal Components Analysis (PCA) derived from the Lidar data set – 2014 Ocean Exploration Trust Dry Tortugas – presented in this digital atlas. The Geotiff is the results of a principle components analysis using 8 derived complexity surfaces from multibeam echosounder surveys - bathymetry mean, bathymetry standard deviation, curvature, curvature plan, curvature profile, rugosity, slope, and slope of slope The PCA is computed in ArcPRO geoprocessing tool “PCA”. The resulting Geotiff can be used to delineate topographically similar seabed features and differentiate benthic habitat types using the three-band color scale. To-date, these data have not been used to create a benthic habitat map.</SPAN></SPAN></P><DIV><DIV><P><SPAN /></P></DIV></DIV></DIV>
