Ellipsoidal Gnomonic Projection by Double Projection Method
Chinese Nautical Chart requests that gnomonic projection should be used if over 60% of the area latitude is over 75°。In this paper,the gnomonic projection equation from the earth ellipsoid to the surface of projection is derived by double projection method.The three important characteristics and application of the ellipsoidal gnomonic projection are described.
