Joint Hydrographic Center

  • Directed by Congress

  • Created by NOAA/UNH MOU June 1999

  • Funded annually through a cooperative agreement grant


Complementary centers l.jpg
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

Center goals l.jpg
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 themes12 l.jpg
Research Themes

Sonar System Capabilities and Limitations

  • Push the limits of resolution (all sorts), coverage, and information content

Depth measurements from side scan sonars

Wide area side scan for habitat mapping

Water column information from multibeam sonars


Research themes13 l.jpg
Research Themes

New Approaches to Multibeam Sonar Data Processing

An example to consider

  • The Request: Develop techniques to speed up the cleaning of multibeam sonar soundings


First find the right question l.jpg
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 l.jpg
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 l.jpg
Valdez Survey Data

A CUBE vs. Traditional Method Trial

  • 5 days

  • Two launches with different multibeam systems

  • 22,227,491 Soundings




Research themes19 l.jpg
Research Themes

Data Visualization and Management

  • 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: NOAA Ship RAINIER


Article 76 bathymetric study l.jpg
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 l.jpg
Research Project

Electronic Chart of the Future

  • 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
