Depth highlight, depth highlight range, and water level offset highlight display and systems
View Patent ↗A digital mapping display and related system for fishing, and other applications.
1. A method of displaying a depiction of an area of a body of water to a display, the method comprising, the steps of:
receiving a user selection of at least one depth to be highlighted on the depiction of the area of the body of water on the display;
identifying a contour corresponding to the at least one depth; and
outputting one or more indications associated with the contour on the display to highlight the contour.
2. The method of claim 1 , wherein the step of receiving the user selection of the at least one depth to be highlighted comprises the step of receiving the user selection of a single depth, and wherein the step of identifying the contour comprises the step of identifying a contour line, and wherein the step of outputting one or more indications associated with the contour comprises the step of outputting one or more indications associated with the contour line on the display to highlight the contour line.
3. The method of claim 1 , wherein the step of receiving the user selection of the at least one depth to be highlighted comprises the step of receiving the user selection of a depth range, and wherein the step of identifying the contour comprises the step of identifying a contour area, and wherein the step of outputting one or more indications associated with the contour comprises the step of outputting one or more indications associated with the contour area on the display to highlight the contour area.
4. The method of claim 1 , wherein the step of identifying the contour comprises the step of identifying a depth contour interval corresponding to the at least one depth, and wherein the step of outputting one or more indications associated with the contour comprises the step of outputting one or more indications associated with the depth contour interval on the display to highlight the contour area.
5. The method of claim 1 , wherein the step of receiving the user selection of the at least one depth to be highlighted comprises the step of receiving the user selection of a depth and a depth highlight range, and wherein the step of identifying the contour comprises the step of identifying a contour area between the depth plus the depth highlight range and the depth minus the depth highlight range, and wherein the step of outputting one or more indications associated with the contour comprises the step of outputting one or more indications associated with the contour area on the display to highlight the contour area.
6. The method of claim 1 , wherein the step of receiving the user selection of the at least one depth to be highlighted comprises the step of receiving the user selection of a depth for a water level offset, and wherein the step of identifying the contour comprises the step of identifying each contour line included on the depiction, and wherein the step of outputting one or more indications associated with the contour comprises the step of outputting one or more indications associated with each contour line on the display to highlight the contour area including an adjustment to each contour line by the water level offset.
7. A method for displaying selected features of a chart of a body of water and associated areas, comprising the steps of:
receiving from a user a selected parameter by which to adjust a display of the chart;
highlighting a contour on the chart on the display when the selected parameter is a desired depth highlight;
highlighting a first contour area on the chart on the display when the selected parameter is a desired depth highlight with a depth contour interval corresponding to the desired depth highlight;
highlighting a contour area on the chart on the display when the selected parameter is a range of contiguous depths or a desired depth highlight and a depth highlight range; and
changing displayed depth values on the display for contour lines on the chart when the selected parameter is a water level offset.
8. A method of adjusting depth indications of contour lines on at least a portion of a chart based on a change in water level of a body of water, comprising the steps of:
receiving a water level offset value indicative of a change in water level from a chart water level existing at a time when the chart was made;
mathematically adjusting the depth indications of the contour lines included on the chart based on the water level offset value; and
displaying adjusted depth indications of the contour lines on at least the portion of the chart.
9. The method of claim 8 , further comprising the step of displaying area above an adjusted depth of zero as land on the chart.
