Abstract

A method in a computer system in a vessel for generating a presentation of a region-of-interest in an original chart image for display on a display screen, the computer system displaying a representation of the vessel moving along a course in the original chart image, the region-of-interest being located along the course proximate to the representation of the vessel, the method comprising: establishing a lens for the region-of-interest, the lens having a magnified focal region for the region-of-interest at least partially surrounded by a shoulder region having a diminishing magnification, the focal region having a size, a shape, and an orientation with respect to the course; receiving one or more signals to adjust at least one of the size, shape, and orientation of the focal region; and, applying the lens to the original chart image to produce the presentation.
