Title: Olympic Coast National Marine Sanctuary - hab110_0204b - Habitat polygons for survey area 0204b
Short Name: hab110_0204b
Status: In Work
Publication Date: 2007-12-31

Benthic habitat polygon coverages are being created for the Olympic Coast National Marine Sanctuary (OCNMS). OCNMS has collected multibeam backscatter, multibeam bathymetry, bottom grab and video data to produce polygon coverages describing seafloor substrate for various areas within the sanctuary. A maximum likelihood classification rule was used to segment the acoustic imagery using local fourier histogram texture features calculated from multibeam xyz data along with multibeam backscatter intensity values. Video and sediment grab information was used to validate the classification. The habitat polygons have attributes for megahabitat, bottom induration, mesohabitat, macrohabitat, slope, complexity, and biology (where direct observations were available), polygon area and perimeter.


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 110_0204a.

Process Steps

Process Step 1

CC ID: 498718

Local fourier histogram (LFH) texture features were calculated from multibeam xyz data 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

CC ID: 498719

A mean and standard deviation was calculated for each data point produced from the 0-7 feature vectors of

Process Step 3

CC ID: 498720

A standard deviation surface was calculated from a 1m multibeam dtm using a 3x3 neighborhood analysis window.

Process Step 4

CC ID: 498721

A multibeam backscatter intensity image was converted to arc ascii grid format.

Process Step 5

CC ID: 498722

Using ArcGis Spatial Analyst, multivariate signatures were collected from 8 separate grids to segment the

Process Step 6

CC ID: 498723

Using ArcGis Spatial Analyst, a maximum likelihood (ML) classification was performed on the 8 previously

Process Step 7

CC ID: 498724

Seafloor slope was calculated from multibeam xyz data and reclassed into four groups (0-5%, 5-15%,

Process Step 8

CC ID: 498725

Standard deviation surface was relcassed into 3 groups (0-0.2, 0.2-0.5, and > 0.5)

Process Step 9

CC ID: 498726

Results of the MLClassify procedure, slope reclass and st_dev reclass were all converted to feature polygons.

Process Step 11

CC ID: 498728

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
