  1. The Benthic Terrain Modeler for Terrain Classification and Visualization of American SamoaMultibeam Data Dept. of Geosciences – Oregon State University Ron Rinehart Dr. Dawn Wright Emily Lundblad Emily Larkin NOAA - Coastal Services Center Josh Murphy Lori Cary-Kothera

  2. What is the BTM? • BTM = Benthic Terrain Modeler • Standalone program compatible with ArcGIS 8.x • Converts bathymetry into a user defined • classification system • Combination of spatial analysis algorithms

  3. Key Questions about the BTM Tool? What is it? How does one use the BTM tool? What are the key features? What are the computer system requirements? Why is this tool needed? Who will use it? Where will this tool be used? Is it a useful tool? When will it be available?

  4. Which Spatial Analysis Algorithms? Slope Multi-Scale Bathymetric Position Index Rugosity

  5. Bathymetric Position Index – How it Works Hilltop Middle Coarse BPI Valley Ridge Crest Fine BPI Stream Channel

  6. Bathymetric Position Index Sloped Surface Slope Stream Valley on a Sloping Hillside Composite BPI

  7. Rugosity

  8. How does it work? Step Four Step Two Step Three Step One Slope Biodiversity Enhanced Benthic Zones? + Composite BPI Bathymetry Fine BPI + + Coarse BPI Rugosity (derived from bathymetry)

  9. How does one use the BTM tool?

  10. How does one use the BTM tool?

  11. BTM Key Features? • Wizard Interface • ‘Learn More’ Buttons • Re-use intermediate results • Re-sampler built in to save time • Classification Dictionary • Dictionary files are XML • Skip the Wizard – Go Straight to the Desired Process

  12. Fine Print :: These are guidelines. As raster size increases so does processing time:: Computer System Requirements? • ArcGIS 8.x with Spatial Analyst • Fast processor >2.0 Ghz recommended • Up to a gigabyte of hard drive space • Rasters need to be ESRI GRID format

  14. Who will use the BTM?

  15. Example from Vatia Bay

  16. Bathymetry of Vatia Bay

  17. BPI of Vatia Bay Coarse BPI Fine BPI

  18. Benthic Terrain Classes of Vatia Bay

  20. Benthic Terrain of Vatia Bay

  21. Rugosity of Vatia Bay

  22. Rugosity of Vatia Bay

  23. Is it Useful? Data need to be ‘ground-truthed’ Mission scheduled for 2005 Potential for including Aspect Potential for Backscatter

  24. When and where will it be available? When: October 2004 Where: http://dusk.geo.orst.edu/djl/samoa Mirror at NOAA CSC
