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.
It supports simple mathematical operations like addition, subtraction, division, and multiplication. Like Binary numbers calculator, it is based on Mathematical calculator. The tricky part is degree notation. The . symbol separates the whole part of the degree from the fractional part.
Decimal degree (decimal notation, DD.DDDDDD°) On this page you can calculate and work with it, as well as Google Maps and Microsoft (Bing) Maps. This system is used mainly because it can be calculated very well.
There is another way to state the size of an angle, one that subdivides a degree using a system different than the decimal number example given above. The degree is divided into sixty parts called minutes. These minutes are further divided into sixty parts called seconds.
Each degree is divided into 60 minutes as usual, but there are no seconds. The minute is expressed as a decimal instead. For example 23° 34.62' is read as "23 degrees 34.62 minutes.
Angles measured in degrees may also be expressed using decimal portions of a degree, for example: \(72.5^{\circ}=72^{\circ} 30^{\prime}\) Converting from decimal to DMS
One way to write spherical coordinates (latitudes and longitudes) is using degrees-minutes-seconds (DMS). Minutes and seconds range from 0 to 60. For example, the geographic coordinate expressed in degrees-minutes-seconds for New York City is: But you can also express geographic coordinates in decimal degrees.
