A line of a map projection along which the principal scale is conserved. This is the case of the meridians in all normal cylindric and conic equidistant projections and the great circles that irradiate from the centre of azimuthal equidistant projections. Note that an equidistant line is always a line of constant scale but not necessarily a conformal line.
