Summary

Description

Benthic habitat polygon coverages are being created for the Olympic Coast National Marine Sanctuary (OCNMS). OCNMS has collected side scan sonar, multibeam backscatter, multibeam bathymetry, bottom grab and video data to produce polygon coverages describing seafloor substrate for various areas within the sanctuary. For this particular area, a maximum likelihood classification rule was used to segment side scan sonar imagery using local fourier histogram texture features calculated from grey scale pixel intensity values. The habitat polygons have attributes for megahabitat, bottom induration, mesohabitat, macrohabitat, polygon area and perimeter.
