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.
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).
Informally, specifying a geographic location usually means giving the location's latitude and longitude. 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
Each of the 1-degree quadrangles is further subdivided into 60 1-minute longitude zones, numbered 00 through 59 from west to east, and 60 1-minute latitude bands, numbered 00 to 59 from south to north. These numbers are always written as two digits, with a leading zero if necessary, and the easting is always followed by the northing.
Plus codes are derived from latitude and longitude coordinates, so they already exist everywhere. [5] They are similar in length to a telephone number (e.g., 849VCWC8+R9) but can often be shortened to only four or six digits when combined with a locality (e.g., CWC8+R9, Mountain View, California). Locations close to each other have similar codes.
The iPhone has finally caught up with its BlackBerry, Windows Mobile 5.0, and S60 competition, at least as far as Google Latitude is concerned. The stalker-centric program is now available for ...
A geographic coordinate system (GCS) is a spherical or geodetic coordinate system for measuring and communicating positions directly on Earth as latitude and longitude. [1] It is the simplest, oldest and most widely used type of the various spatial reference systems that are in use, and forms the basis for most others.
Click the email icon. The geographical coordinates are embedded in the email link which is then displayed. The coordinates are the two numbers displayed immediately after the letters "cp=". The latitude and longitude are separated by a tilde ( ~ ). The latitude is displayed first, and both coordinates are displayed in decimal degrees format.
