File:Vertical perspective SW.jpg to appear as POTD soon

[edit]

Hello! This is a note to let the editors of this article know that File:Vertical perspective SW.jpg will be appearing as picture of the day on November 28, 2015. You can view and edit the POTD blurb at Template:POTD/2015-11-28. If this article needs any attention or maintenance, it would be preferable if that could be done before its appearance on the Main Page.  Chris Woodrich (talk) 00:42, 11 November 2015 (UTC)Reply

General Perspective projection
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.Map: Strebe, using Geocart
