Definition

A CONFORMAL PROJECTION of the cylindrical type. The EQUATOR is represented by a straight line true to SCALE; the GEOGRAPHIC MERIDIANS are represented by parallel straight lines perpendicu­lar to the line representing the EQUATOR; they are spaced according to their distance apart at the EQUA­TOR. The GEOGRAPHIC PARALLELS are represented by a second system of straight lines perpendicular to the family of lines representing the MERIDIANS, and there­fore parallel with the EQUATOR. CONFORMALITY is achie­ved by mathematical analysis, the spacing of the PARAL­LELS being increased with the increasing distance from the EQUATOR to conform with the expanding SCALE along the PARALLELS resulting from the MERIDIANS being repre­sented by parallel lines. Since RHUMB LINES appear as straight lines and DIRECTIONS can be measured directly, this PROJECTION is widely used in NAVIGATI­ON.
