The General Perspective projection is a map projection used in cartography in which the Earth is depicted as viewed from a finite distance above its surface. If the view precisely faces the center of the Earth, the projection is a vertical perspective projection; otherwise, it is a tilted perspective projection. Here is shown a vertical perspective from an altitude of 35,786 km over (0°, 90°W), corresponding to a view from geostationary orbit. Due to the horizon as seen from the viewpoint position, the projection always shows less than half of the Earth's surface: in this case neither of the North and South Poles is visible.
