An off-line charting facility accepts the data from both configurations, producing tide reduc- tion, change of vessel position and general edit- ing of all collected data. The data can be from more than one vessel or from previous surveys. A digitizing feature allows additional informa- tion to be added to the database and interactive computer-aided techniques are used to produce the contours. Final charts and overlays are printed on a high-quality graphic plotter. The modular design allows the data collection and charting operations to be performed in parallel. The charting system can also be used dynamically to produce dredge control data for computer-aided graphical displays to indicate: guidance for the dredger; location of dredge leads and quality control of the dredge area; cross-section profiling showing current with de- sired overlay; and pre- and post-dredge survey contours to allow volumetric calculations.

The company has now made available a series of high-tech aluminum pre-fab sectional mod- ular consoles to fit any wheelhouse or open com- mand bridge. The design of each innovative control system is engineered to place all essential instrumenta- tion in one easily accessible helm station com- mand center. The layout features logical place- ment of engine instrumentation, navigation equipment and communication equipment around the helm's wheel. According to GALAX, these sophisticated modular console systems only could have been custom-ordered in the past, but now the custom- er can kit-assemble his own console for up to 70 percent off custom prices.
