Abstract

In non-limiting examples of the present disclosure, systems and methods for dynamically updating contour maps are provided. A first water level for a body of water may be determined by a computing device. A location within the body of water may be identified. A second water level relating to the identified location within the body of water may be determined, and the second water level and the first water level may be compared. Upon comparing the first and second water levels, a contour map for the body of water may be automatically updated.

Dependent claims

A method for dynamically updating a contour map associated with a body of water, the contour map including g water depth values for the body of water, the method comprising:

using at least one processor:
loading a pre-existing contour map of the body of water, the pre-existing contour map including a water depth value at a plurality of positions within the body of water;
displaying a graphical user interface including a selectable control that is selectable by a user via a user input device to selectively enable and disable an automatic contour map update function on a display;
determining that the selectable control has been selected to enable the automatic contour map update function;
measuring a position on the body of water using a position sensor, the position also being included within the pre-existing contour map;
measuring a current depth of the body of water at the position using a depth sensor;
extracting a depth value of the body of water indicated by the pre-existing contour map at the position;
determining a difference between the depth of the body of water indicated by the pre-existing contour map at the position and the current depth of the body of water at the position, the difference representative of a physical change in the depth of the body of water at the position and at least one other position;
automatically updating the pre-existing contour map to indicate the physical change, including updating the water depth values of the pre-existing contour map by shifting at least the water depth values at the position and the at least one other position by the determined difference;
and
displaying the updated contour map including the updated water depth values in the graphical user interface.
