Equidistant conic projection

Length loyalty ( equidistant or the even isometric ) conic projections are card network designs in which the earth's surface is projected onto a cone. In normal situation, the meridians are mapped isometrically. The lowest distortion happens at also length-preserving contact or the two also length-preserving cut circles. About the location of the contact or intersection circles can be the card network design for different areas to optimize.

Leaving the Berührkreis to the equator migrate arises as a limiting case (cone with infinite height ) the length-preserving cylindrical projection ( Equirectangular ).
