Methods and algorithms for solving the problem of selecting boundary points of aircraft basing areas
The paper considers a set of methods and algorithms that allows determining the geodetic coordinates of the vertices of a convex polygon (with the number of vertices not exceeding a given one), limiting the initial set of points with known geodetic coordinates. When solving the problem, we developed the following: an algorithm for determining the geodetic coordinates of the polygon vertices; proposals for improving the methodology for constructing the boundaries of the area where points of the aircraft basing areas are located; algorithms for determining the set of points that are the vertices of a convex polygon that limits the initial set of points; an algorithm for reducing the number of vertices of a convex polygon; methods for selecting points by direction and by range; a method for determining the angle at the vertex of a polygon; a method for determining the geodetic coordinates of the vertices of a polygon that do not belong to the original set of points. To effectively solve the problem, we examined several different algorithms, e.g. the Jarvis March algorithm and the Graham scan. The use of the above methods and algorithms makes it possible to determine the geodetic coordinates of the vertices of a convex polygon (with the number of vertices not exceeding a given one), limiting the initial set of points with known geodetic coordinates, and increases the validity and accuracy of determining the geodetic coordinates of the boundary points of the aircraft basing areas.
