The method of claim 1 wherein the chart comprises at least information selected from a hardness of the bottom of the water body, a content of the bottom of the water body, a weed content of the water body, or a current present in the water body. 16. The method of claim 1 wherein the chart further comprises at least one or more spot depths or at least one continuous depth contour line at a selected depth. 17. The method of claim 1 wherein the selected depth comprises a thermocline region. 18. The method of claim 1 wherein the surface of the contour line is representative of a portion of the body of water free from a sheet of ice. 19. A system for displaying a graphical output of one or more selected areas of a body of water, the system comprising one or more computer readable memories including: one or more codes directed to at least one chart of one or more regions of a body of water, the chart comprising a plurality of bottom depths below a surface of the one or more regions of the body of water, the chart being configured to be output on the display; one or more codes directed to receiving information associated with at least one depth to be highlighted on the display simultaneously with the chart; one or more codes directed to processing information associated with the selected depth with information from the chart to identify at least a contour line at the selected depth; and one or more codes directed to outputting one or more indications associated with the contour line on the display to highlight. 20. A method to graphically output a depiction of one or more selected areas of a body of water together with adjacent contiguous land surface areas above the water surrounding said water body to a GPS Display Device, the display being coupled to a GPS device, the method comprising: providing at least one chart out of a plurality of charts of one or more regions of a body of water from a computer readable memory or memories, the chart comprising a plurality of bottom depths below a surface of the one or more regions of the body of water, the chart being configured to be output on the display;selecting a range of depths to be highlighted simultaneously with the chart on the display;processing information associated with the selected depth range with information from the chart to identify the selected depth range; andoutputting one or more indications associated with the one or more regions on the display to highlight the selected depth range. 21. A method to graphically output a depiction of one or more selected areas of a body of water together with adjacent contiguous land surface areas above the water surrounding said water body to a GPS Display Device, the display being coupled to a GPS device, the method comprising: providing at least one chart of one or more regions of a body of water, the chart comprising a plurality of bottom depths below a surface of the one or more regions of the body of water together with a land surface adjacent to the body of water, the chart being configured to be output on the display; andselecting a value consisting of either a positive off-set or a negative off-set by which to modify at least one depth label of the bottom depths and to modify a display of the land surface adjacent to the body of water on the display. 22.
