Abstract
In certain embodiments, determining maritime paths includes accessing a feasibility matrix comprising feasibility values for locations of an area. A feasibility value indicates navigability at a location. One or more non-navigable locations represent one or more barriers. Waypoints around the barriers are determined. A cost matrix comprising cost values is calculated. A cost value indicates a distance between two points of a set of points, where the set of points comprises one or more start points, one or more end points, and the waypoints. Dijkstra's technique is applied to a selected start point and a selected end point to yield a shortest length path between the selected start point and the selected end point.
