Abstract :
Kumar Mapping (KMap) System is based on a “bird’s-eye-view” snapshot picture of the Earth’s surface in small-size ellipsoidal trapezoids. At the poles, the smaller side of the trapezoid will be zero and it will become triangular. Each trapezoid is mapped individually and independently of the adjoining neighbor. The smaller the area size, the flatter will be the trapezoid, which on paper will become a trapezium. Keeping the trapezium sides equal to the actual lengths of the latitudinal or longitudinal arcs of the corresponding trapezoid, distortions due to flattening of the bulge will be practically zero for nautical charts. The trapeziums or triangles are not converted to squares or rectangles, and charts will have true North and scale with no discontinuity in coordinates. The Earth’s ellipsoidal ocean surface is charted as a mosaic of small trapezium/triangle shaped charts producing seamless coverage with adjoining KChart and/or KMap.
