If the length of the line segment connecting two projected points on the plane is proportional to the geodesic (shortest surface) distance between the two unprojected points on the globe, then we say that distance has been preserved between those two points. An '''equidistant projection''' preserves distances from one or two special points to all other points. The special point or points may get stretched into a line or curve segment when projected. In that case, the point on the line or curve segment closest to the point being measured to must be used to measure the distance.
* [[Plate carrée projection|Plate carrée]]: Distances from the two poles are preserved, in equatorial aspect.
* [[Azimuthal equidistant projection|Azimuthal equidistant]]: Distances from the center and edge are preserved.
* [[Equidistant conic projection|Equidistant conic]]: Distances from the two poles are preserved, in equatorial aspect.
* [[Werner cordiform projection|Werner cordiform]] Distances from the [[North Pole]] are preserved, in equatorial aspect.
* [[two-point equidistant projection|Two-point equidistant]]: Two "control points" are arbitrarily chosen by the map maker; distances from each control point are preserved.
