Parent Layer: Principal Components Analysis - Highlighted Seafloor Features

Name: 2021 Tortugas Ecological Reserve North

Display Field:

Type: Raster Layer

Geometry Type: null

Description: <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 – 2021 Tortugas Ecological Reserve North – 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 STYLE="margin:10 0 4 0;"><SPAN /></P></DIV></DIV></DIV>
