Office of National Marine Sanctuaries, 2024: Olympic Coast National Marine Sanctuary - hab122_0702 - Habitat polygons for HMPR-122-2007-02 survey, https://www.fisheries.noaa.gov/inport/item/40075.
Full Citation Examples
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.

Abstract: |
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. |
Purpose: |
These data are intended for science researchers, students, policy makers, and the general public. The data can be used with geographic information systems (GIS) software to display seafloor characteristics within the survey area 121_0702. |

Process Steps
Process Step 1
Description: |
Local fourier histogram (LFH) texture features were calculated from the side scan sonar imagery using a 10x10 block size (Cutter et al.2003).Cutter, G.R. Jr., Y. Rzhanov, L.A. Mayer. 2003. Automated segmentation of seafloor bathymetry from multibeam echosounder data using local Fourier histogram texture features. Journal of Experimental Marine Biology and Ecology. 285-286: 355-370. |
---|
Process Step 2
Description: |
A mean and standard deviation was calculated for each data point produced from parameterized LFH feature vectors. Ascii grids were created for each LFH feature vector (other than LFH_0). |
---|
Process Step 3
Description: |
A multibeam backscatter intensity image was converted to arc ascii grid format. |
---|
Process Step 4
Description: |
Using ArcGis Spatial Analyst, multivariate signatures were collected from the backscatter image stacked with the 7 LFH feature vectors. |
---|
Process Step 5
Description: |
Using ArcGis Spatial Analyst, a maximum likelihood (ML) classification was performed on the 8 previously mentioned ascii grids. |
---|
Process Step 6
Description: |
Results of the MLClassify procedure were filtered using a Majority Filter using the eight|half parameter and then finally converted to feature polygons. |
---|
Process Step 7
Description: |
Attributes were added according to Greene et al (1999).Greene, H.G., M.M. Yoklavich, R.M. Starr, V.M. O'Connell, W.W. Wakefield, D.E. Sullivan, J.E. McRea, Jr., G.M. Cailliet. 1999.A classification scheme for deep seafloor habitats. Oceanologica Acta. 22(6):663 |
