## Geographic Coordinates

### Desription

"A geographic coordinate system is a coordinate system that enables every location on the Earth to be specified by a set of numbers or letters. The coordinates are often chosen such that one of the numbers represents vertical position, and two or three of the numbers represent horizontal position. A common choice of coordinates is latitude, longitude and elevation."

"The World Geodetic System is a standard for use in cartography, geodesy, and navigation. The latest revision is WGS 84 [...], established in 1984 and last revised in 2004."

### Notes

At the NumericalChameleon you can enter WGS84 based coordinates in many ways:
Latitude/Longitude (WGS 84) [9.9, 9.9]]
Latitude and Longitude, each separated by a comma, expressed in decimal form. Decimal separator can be the dot or the comma.
Example: 48.13856021337852, 11.572996973991394
See also http://en.wikipedia.org/wiki/Longitude
and http://en.wikipedia.org/wiki/Latitude
Latitude/Longitude (WGS 84) [9° 9.9' N, 9° 9.9' E]
Latitude and Longitude, each separated by a comma, expressed in angular degree, angular minute und a geographic indicator (N=north, S=south, E=east and W=west). Decimal separator can be the dot or the comma.
Example: 48° 8.313612802711106' N, 11° 34.37981843948364' E
Latitude/Longitude (WGS 84) [9° 9' 9.9" N, 9° 9' 9.9" E]]
Latitude and Longitude, each separated by a comma, expressed in angular degree, angular minutes, angular seconds and a geographic indicator (N=north, S=south, E=east and W=west).
Example: 48° 8' 18.816768162666335" N, 11° 34' 22.789106369018555" E
Universal Transverse Mercator (UTM) [9U 9.9 9.9]
An UTM-coordinate consists of the UTM zone number, an easing coordinate in that zone and the northing coordinate in that zone, each separated by a blank.
Example: 32U 691412.5188777333 5334902.7385507

Maidenhead Locator
The Maidenhead Locator consists of 6 characters. Each 2 characters for the Field (A-R), Square (0-9) and Subsquare (A-X).
Example: JN58SD

Military Grid Reference System (MGRS)
The coordinate in the MGRS consists of the grid zone designator (UTM-Zone+UTM-Band), the the 100,000-meter square identifier and a numerical location.
For now there is no support for MGRS references in polar regions north of 84°N and south 80°S.
Example: 32UPU9141334903

Earth-Centred, Earth-Fixed Cartesian Co-Ordinate (ECEF)
The ECEF is a cartesian coordinate system and represents positions as an X, Y and Z.
Example: (4177563.1907362374,855478.9576390916,4727171.597994833)

### Useful Features

Google Maps
With a click on the button called "Google Maps" your internet browser opens Google Maps with the coordinates that you have entered.
