NOAA/UNH Joint Hydrographic Center
Education and Research at the University of New Hampshire
www.ccom.unh.edu
Joint Hydrographic Center
• Directed by Congress• Created by
NOAA/UNH MOU June 1999
• Funded annually through a cooperative agreement grant
Complementary Centers
• NOAA/UNH Joint Hydrographic Center (JHC)– A Government and University Organization
• UNH Center for Coastal and Ocean Mapping (C-COM)– Provides for participation of other government agencies
and private sector
NSF, ONR, NRL, DARPA, USGS, GEBCO
Industrial Consortium
Center Goals
• To be a world leader in the development of hydrographic & ocean mapping technologies and approaches
• To expand the scope and applications of ocean mapping
• To educate a new generation of hydrographers and ocean mappers that can meet the growing needs of both government agencies and the private sector.

Research Themes
• The Request: Develop techniques to speed up the cleaning of multibeam sonar soundings
New Approaches to Multibeam Sonar Data ProcessingNew Approaches to Multibeam Sonar Data Processing
An example to consider
First, find the right question…
• What’s really the problem?
• What’s taking the time?
• What does the end user really need?
What is it that we really need to solve our problem?
Automated Multibeam Sonar Processing
• CUBE– Combined Uncertainty and Bathymetric
Estimator– Creates a high resolution digital elevation
model rather than a (huge) bunch of individual soundings
– Being incorporated into leading hydrographic software products
Valdez Survey Data
• 5 days
• Two launches with different multibeam systems
• 22,227,491 Soundings

Research Themes
• The Navigation Surface– Archiving a digital elevation model rather than
a shoal-biased set of soundings– Lets us generalize the products, not our original
survey data
Data Visualization and Management
This has been our archive product
Snow Passage Depth Plot H10949
This will be our archived product
Data: NOAA Ship RAINIER
Article 76 Bathymetric Study
• Identify areas of potential claim
• Identify existing data pertinent to LOS
• Define areas of potential claim where existing data is insufficient
• Determine survey requirements and costs to fill in data gaps
Research Project
• Next Generation improvements– What improved capabillity can be implemented
in today’s electronic charting technology
• Revolutionary changes– What should an electronic chart look like– Unconstrained by existing ECDIS and ENC
standards, formats, and conventions
Electronic Chart of the Future
