The 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.
