Decimal degrees (DD) is a notation for expressing latitude and longitude geographic coordinates as decimal fractions of a degree. DD are used in many geographic information systems (GIS), web mapping applications such as OpenStreetMap , and GPS devices.
The numerical values for latitude and longitude can occur in a number of different units or formats: [2] sexagesimal degree: degrees, minutes, and seconds : 40° 26′ 46″ N 79° 58′ 56″ W; degrees and decimal minutes: 40° 26.767′ N 79° 58.933′ W; decimal degrees: +40.446 -79.982; There are 60 minutes in a degree and 60 seconds in a ...
Geodetic latitude and geocentric latitude have different definitions. Geodetic latitude is defined as the angle between the equatorial plane and the surface normal at a point on the ellipsoid, whereas geocentric latitude is defined as the angle between the equatorial plane and a radial line connecting the centre of the ellipsoid to a point on the surface (see figure).
Coordinate values (latitude, longitude, and altitude) should be delimited by spaces. The decimal point is a part of the value, thus must usually be configured by the operating system. [a] Multiple locations should be represented by multiple lines. Latitude and longitude should be displayed by sexagesimal fractions (i.e. minutes and seconds).
Latitude at bottom edge of map, in decimal degrees; left = -122.604 Longitude at left edge of map, in decimal degrees; right = -122.253 Longitude at right edge of map, in decimal degrees; Precision. Longitude: from West to East this map definition covers 0.351 degrees. At an image width of 200 pixels, that is 0.0018 degrees per pixel.
A geographical mile is defined to be the length of one minute of arc along the equator (one equatorial minute of longitude) therefore a degree of longitude along the equator is exactly 60 geographical miles or 111.3 kilometers, as there are 60 minutes in a degree. The length of 1 minute of longitude along the equator is 1 geographical mile or 1 ...
Latitude at bottom edge of map, in decimal degrees; left = -118.348 Longitude at left edge of map, in decimal degrees; right = -118.128 Longitude at right edge of map, in decimal degrees; Precision. Longitude: from West to East this map definition covers 0.22 degrees. At an image width of 200 pixels, that is 0.0011 degrees per pixel.
Longitude at right edge of map, in decimal degrees; Precision. Longitude: from West to East this map definition covers 25 degrees. At an image width of 200 pixels, that is 0.125 degrees per pixel. At an image width of 1000 pixels, that is 0.025 degrees per pixel. Latitude: from North to South this map definition covers 17.5 degrees. At an image ...
