Abstract
A navigation system includes a navigation database and a route generator. The route generator receives an avoidance, generates a concave polygon representing the avoidance with respect to four-dimensional data of the navigation database, identifies a displacement vector of the avoidance, shifts the concave polygon using the displacement vector, identifies each gap between vertices of the shifted concave polygon, adds an added edge to the to connect vertices across each identified gap, determines, for each edge of the concave polygon, if the edge includes an internal edge, removes each internal edge from the concave polygon, compares the concave polygon to the plurality of cells, identifies one or more cells in which the concave polygon is located, and outputs a navigation alert based on the identified one or more cells.
