Standard Map Projections

           The some of the standard ways to project the maps are discussed here:-
       Conical Projections:-  Conical projections are made as if a large paper cone rested on the top of the globe with its point above the North Pole and its bottom edge touching the globe somewhere north of the Equator. When the cone is cut, a flat map unfolds, shape like a fan. Conical projections are best for showing areas in the middle latitudes.
         Cylindrical Projections:-  It show the globe as if it where projected onto a large sheet of paper surrounding it. Those points around the center,near the poles are stretched causing landmarks far to the north and south to look much larger than they really are.
        Azimuthal Projections:- Azimuthal projections are also called plane or zenithal projections. To create these, the mapmaker designates one point of the globe as the center of the map , the point can be any where and projects an image as if a flat piece of stiff paper were resting there.
