Enhancing Lighted Navigational Aids Using GIS Mapping

This paper proposes a methodology to help navigate more safely using GIS Mapping. A proposed methodology can build up lit maps to most bay areas and port entrances. A detailed description of the range ring methodology is given and recommendations are drawn. It is concluded that the mapping of a lit area will help revision and maintenance of existing withdraws of bay lighting. A practical implementation of the methodology is applied to Great South Bay area in New York. Results show that there is a need to increase the buoys light and revise existing buoys locations in order to make night navigation through the bay safer.
