IOCM Standards and Specifications – Durham NH – April 18-19, 2006
U.S. Coral Reef Task Force GoalU.S. Coral Reef Task Force Goal
Produce comprehensive digital maps of all shallow (<30m) coral reef ecosystems in the
United States and characterize priority moderate-depth reef
systems by 2009.
Shallow Water MappingShallow Water Mapping
IKONOS Imageof Midway Island
Estimated Depths(Stumpf & Holderied)
Habitat Classification Manual Interpretation
Aerial and satellite data being used for mapping in shallow areas.In most areas NOAA uses IKONOS imagery
to produce shallow-water (< 30m) benthic habitat maps.

•2005 and 2006 IHO Order values are estimations, as final processing and QA/QC are in progress. Final results may vary from these goals.
Issues:‘Strumming’/vibration in
temporary pole-mount (2004)
Error measurements– initial offset (in)accuracy– Importance of a good patch
test
Line spacing/Use of outer beam data
Coordination with Partners
-i.e. advance notice to COOPS for tide request
How to share responsibility and expertise for project planning, data acquisition and processing, product generation, documentation
• Funding, personnel, time
Balancing different operational needs (i.e. ROV versus multibeam) at sea and prioritization of divergent project areas

Map to IHO Standards in Priority Areas
• OCS participated in 2002 Kilo Moana survey in NWHI• OCS and NMAO did installation and original certification of Hi’ialakai
and Nancy Foster mapping systems. CRCP and OCS collaboration on re-calibration and re-certification of Hi’ialakai and AHI mapping systems now underway – collaborative yearly updates?
• Portions of USVI survey in 2005 & 2006 were conducted to IHO standards with documentation.
• Joint CRCP/OCS charting surveys for harbors in Saipan, Tinian, & Rota, CNMI, are planned for early 2007 using AHI.
