Mapinfo 10 intersection between circle7/14/2023 Conformal projections, for example, are preferred for nautical charts or small scale maps because they locally preserve angles necessary for navigation and survey drawings. The choice of projection depends on a map’s use, scale and audience. The only exception is a Globe, which preserves angles, areas and distances perfectly. Projection almost always introduces distortion, most projections cannot preserve angles, areas and distances at the same time, they may be conformal (angle-preserving), equal-area (area-preserving) or equidistant (distance preserving) but not all at once. The task of projecting, or unfolding the spherical Earth onto a flat map, is an age old problem in cartography.
