Maximizing Mariner Effectiveness Through Fusion of Marine and Visualization Technologies
The goal of the Chart-of-the-Future Project is to investigate ways to provide more effective information to the mariner in order to maximize safety and efficiency of navigation. We proceed by developing proof of concept prototypes to test new ideas and utilize new technologies. We evaluate these prototypes either through interviews with potential users or by conducting more formal human factors studies. The following is a list of sub-projects.

The Chart Update Mashup (ChUM©) is a way to visualize critical chart corrections (from the Local Notice to Mariners) overlaid on NOAA Nautical Charts in an intuitive, geo-reference way. An interactive table allows for exploring and filtering the updates. The NOAA Chart Catalog is viewable as outlines and the NOAA Coast Pilot is automatically cross-linked with geo-referenced data to the chart. ChUM© is based on the Google Map V3 Api and accessible online at: http://vislab-ccom.unh.edu/~briana/chum/.

The main idea behind creating the GeoCoastPilot is to bring the existing Coast Pilot™ publication into the realm of modern interactive media. The information in the Coast Pilot™ books is often given piecemeal, leading mariners to read whole sections about a particular area of interest in order to pick out the few fragments that will be relevant on their next approach. The GeoCoastPilot will provide linkages between the written text, 2D and 3D views, web content, and other primary sources such as charts, maps, and related federal regulations.

GeoNav3D integrates detailed bathymetric models, tide and current models, GPS, and sonar into a single 3D computer interface. A voyage planning feature allows for depth information to be displays at the estimated time of arrival using tidal forecasts.
We have been conducting an investigation of ways to present photographic imagery to the mariner to better capture the utility of the early coastline sketches. Our focus has been on navigation in restricted waters, using the Piscataqua River as a test area. Through our investigation, we have developed a new method for presenting photographic imagery to the mariner, in the form of a series of panoramic images progressing down the channel.

Inexperienced helmsmen often oversteer because of the lag that occurs between changing the rudder angle and a change in the vessel’s heading. Predictive displays are a common way of mitigating the effect of lag on human control. Accordingly we developed a predictive display to show the position and heading of a vessel a short time in the future. With this display, the helmsman’s task becomes that of keeping the predictor on the planned path. In effect, the predictor is steered, not the vessel.

A specification is being developed to enable hydrographic and maritime safety agencies to encode AIS message contents using XML. AIS binary messages are an effective means to digitally communicate relevant ports/waterways information related to dynamic and real-time information. Learn more about AIS .
