CONVERSIONS BETWEEN HUNGARIAN MAP PROJECTION SYSTEMS

Abstract

\Vhen different map projection systems are applied simultaneously over a given area, the need for conversion permanently arises in the overlapping areas of these systems. Conversions, however, cannot always be made by closed matnematical formulas and in these cases it frequently raises serious problems to apply a correct transformation method. Hence such an algorithm and program package was developed for all combination conversion between Hungarian map projection systems and their reference surfaces which does not cause any difficulties even for users having no deeper knowledge in map projections.
