Abstract:
1. A method for using a computer and a global positioning system device to facilitate the creation and dissemination of marine navigational waypoints and routes, said method comprising the steps of: inputting into the computer, updateable waypoint data bases containing, electronic marine chart data, said data bases including, name, charts, description, position, latitude, and safety notes, said waypoints being designated by acronym, said waypoints being further designated by reference to a standardized reference to aids to navigation, geographic location and latitude and longitude with said waypoints designated to refer to preferred deep water positions, said waypoints being cross referenced to applicable hard copy charts, inputting into the computer data bases, compiled navigational routes, said data bases comprising successive waypoints derived in said waypoint data bases from a first waypoint to a last waypoint of a desired route, said data to be designated by, route waypoint, waypoint name, distance, leg length, in miles, course in true bearing, and specific route data, including shallow water, bridge heights, warnings and reference information pertinent to the waypoints shown, inputting data from the computer into said global positioning system device, inputting into the computer, data from said global positioning system device creating thereby a transfer of compiled route data between the computer and said global positioning system device, modifying said navigational routes using the computer and said global positioning system device, thereby updating said routes to include current conditions relevant to each of said waypoints, modifying data sets in the computer to make correct reference to said marine charts, and truncating said data sets to facilitate printing reports suitable for manual use in the event of failure of said global positioning system device or computer.
