<P> A map projection is a systematic transformation of the latitudes and longitudes of locations from the surface of a sphere or an ellipsoid into locations on a plane . Maps can not be created without map projections . All map projections necessarily distort the surface in some fashion . Depending on the purpose of the map , some distortions are acceptable and others are not ; therefore , different map projections exist in order to preserve some properties of the sphere - like body at the expense of other properties . There is no limit to the number of possible map projections . </P>
