Marine electronic device for generating a route based on water depth

A method comprising:

• receiving, via a user interface, a first user input defining a minimum water depth value for a route on the body of water;
• receiving, via the user interface, a second user input defining a maximum water depth value for the route;
• causing a chart to be displayed on the user interface;
• receiving, via the user interface, a third user input directed to the chart defining an ending point;
• and
• generating, using a processor, a continuous route from a starting location to an ending location corresponding to the ending point based on the maximum water depth value and the minimum water depth value.

A marine electronic device comprising:

• a user interface;
• a processor;
• and
• a memory having computer program code stored thereon, the memory and the computer program code are configured to, with the processor, cause the marine electronic device to:
• determine a minimum water depth value for a route on a body of water;
• determine a second user input defining a maximum water depth value for the route;
• receive, via the user interface, a third user input defining an ending point;
• determine a continuous geographical area extending between a starting location and an ending location that comprises a water depth that satisfies both the maximum water depth value and the minimum water depth value, wherein the ending location corresponds to the ending point provided through the third user input;
• and
• generate a continuous route from the starting location to the ending location formed of a plurality of geographical locations within the determined continuous geographical area.
