Longitude: from West to East this map definition covers 1.01 degrees. At an image width of 200 pixels, that is 0.005 degrees per pixel. At an image width of 1000 pixels, that is 0.001 degrees per pixel. Latitude: from North to South this map definition covers 0.44 degrees. At an image height of 200 pixels, that is 0.0022 degrees per pixel.
Null Island is the location at zero degrees latitude and zero degrees longitude), i.e., where the prime meridian and the equator intersect The name is often used in mapping software as a placeholder to help find and correct database entries that have erroneously been assigned the coordinates 0,0.
The calculation is essentially the conversion of the equatorial polar coordinates of Mecca (i.e. its longitude and latitude) to its polar coordinates (i.e. its qibla and distance) relative to a system whose reference meridian is the great circle through the given location and the Earth's poles and whose polar axis is the line through the ...
Positions are traditionally given using degrees, minutes, and seconds of arcs for latitude, the arc north or south of the equator, and for longitude, the arc east or west of the Prime Meridian. Any position on or above the Earth's reference ellipsoid can be precisely given with this method.
Longitude at right edge of map, in decimal degrees; Precision. Longitude: from West to East this map definition covers 0.577 degrees. At an image width of 200 pixels, that is 0.0029 degrees per pixel. At an image width of 1000 pixels, that is 0.0006 degrees per pixel.

When this is not the case, as in astronomy or for geographic coordinates (latitude and longitude), degree measurements may be written using decimal degrees (DD notation); for example, 40.1875°. Alternatively, the traditional sexagesimal unit subdivisions can be used: one degree is divided into 60 minutes (of arc), and one minute into 60 ...
Thus 4 minutes (more precisely 3 minutes, 56 seconds), in the equation of time, are represented by the same distance as 1° in the declination, since Earth rotates at a mean speed of 1° every 4 minutes, relative to the Sun. An analemma is drawn as it would be seen in the sky by an observer looking upward.
