US Patent 10460484 Systems and associated methods for route generation and modification

A touch screen may be utilized by a marine electronic device to easily enter a route in relation to a chart. The marine electronic device may automatically determine and join geographic points associated with the chart to generate a route based on a touch pattern. The marine electronic device may be configured to complete the route to form a route loop in instances in which the start and end of the touch pattern are within a predetermined distance. The completion of the route may be accomplished by connecting the end point to the start point or by “snapping” the end point to the start point, e.g. shifting the end point to the start point. Additionally or alternatively, a user may use pre-determined route snippets to quickly and easily alter a route.
