Determining a boundary enclosing a region of interest for a body of water
First Claim
1. A marine device located within a marine vessel, the marine device comprising:
- a display;
a memory unit configured to store an offset direction and an offset distance associated with a boundary defining mode;
a location determining component configured to generate geographic location data indicative of a geographic location of the marine device while the marine vessel navigates a body of water having a natural shoreline along a perimeter of the body of water;
a user interface configured to receive the offset direction and the offset distance from the traveled path to the natural shoreline; and
a processing unit coupled with the display, the location determining component, and the memory unit, the processing unit configured to;
determine a path traveled by the marine vessel based on the geographic location data,determine an offset based on the offset direction and the offset distance,determine a boundary formed by applying the determined offset to the traveled path, the determined boundary at least partially enclosing a region of interest and corresponding to the natural shoreline,associate a water depth of zero with the determined boundary, andcause the display to present a map including the region of interest;
wherein the offset direction is a side of the marine vessel for which the offset distance is to be applied.

Abstract
Various techniques are described that relate to the manner in which marine devices may generate and display a water depth contour map while navigating a body of water. The contour map includes contour lines associated with determined contour line data that indicate geolocations of underwater terrain existing at depths of the body of water specified by the contour lines. A boundary enclosing a region of interest for the body of water may be determined and the contour map may include contour lines determined using the determined contour line data within the region of interest. The boundary may correspond to a natural shoreline along the perimeter of a body of water or a portion of the body of the water. The boundary corresponding to a shoreline may be automatically identified based on a stored map by identifying geographic locations along the perimeter of the body of water.
