What standards are reasonable for CRCP mapping needs?

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.

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.
