                 Bird's-Eye View mapsThe so-called bird's-eye view maps
                (oblique views) stands between the artistic perspective view and
                the map itself. It is a picture drawn or photographed at an
                angle from above as seen through the eyes of a bird. It helps to
                understand the map which is usually harder to interpret and is
                therefore often found in the introduction to school atlases.
                Bird's-eye views are also popular for touristic advertising or
                as a souvenir. |
