Sensitive Sea Areas (PSSAs) on electronic charts as mandated by the International
Maritime Organization (IMO).
Revolutionary:
Within the context of the “revolutionary” effort, Colin Ware, Kurt Schwehr, Matt
Plumlee, Roland Arsenault and Matt Quinn have been extending the capabilities of
GeoZui4D (as described above) as well as developing specific applications for the chart
of the future. The GeoZui4D version that has become the base for the Chart of the Future
project is now called GeoNav4D. Many of the new capabilities were described past
reports (and in the description of the flow visualization above). With the arrival of Kurt
Schwehr, the Chart of the Future project has undergone a re-evaluation in terms of the
immediate focus being taken. During the past few years, the Center has demonstrated a
number of charting components that have gained wide notice. For example, these pieces
include:
• Path planning with time dynamic depth contours for safe, caution, and grounding
• Haptic perception of bathymetry
• Pseudo-photo realistic renderings with billboards and 360 disk panorama models
• Basic ship position decoding from AIS messages
• Tide based flow modeling
• Multi-ship and marine mammal coordinated displays
• Multiple view coordination
• Analysis of a predictor for ship behavior to assist novice ship drivers
The Center has met with NOAA, the USCG RDC, and the British Admiralty to start
evaluating the components separately and in concert for possible test scenarios. As
discussed in the previous year’s reports, the Center is working with NOAA on a
showcase/demonstration project in the Port of Norfolk/Hampton Roads, VA. The target
date is a presentation in conjunction with the US Hydro Conference in Norfolk in spring,
2007. The Center will be deploying an AIS logging station to the area along with
processing and correlating the data products for the site. The goal is to show the best
possible scenarios with today’s technology when all data types are present and integrated
which currently not the case for any port area within the continental US.
For the Chart of The Future project, Kurt Schwehr has embarked on an analysis of ship
behavior and accidents. Initial work has established logging of the national Automatic
Identification System (AIS) network created by the USCG Research and Development
Center. This data can then be correlated with incidents and provide specific instances of
ship behavior. To complement this data stream, the Center is looking at events listed in
reports compiled by the USCG MISLE Marine Casualty database. The Center has
developed additional expertise with AIS by deploying an initial AIS receive-only station
in Portsmouth, NH for several months along with installing a SOLAS class RM808 AIS
unit provided by our industrial consortium partner L3/Klein. In the future, the Center
will deploy AIS stations as needed based on coverage holes in the USCG AIS network.
