Defining Parameters. The coordinate origin of WGS 84 is meant to be located at the Earth's center of mass; the uncertainty is believed to be less than 2 cm.. The WGS 84 meridian of zero longitude is the IERS Reference Meridian, 5.3 arc seconds or 102 metres (335 ft) east of the Greenwich meridian at the latitude of the Royal Observatory.. The WGS 84 datum surface is an oblate spheroid with. Latitude (φ) is a geographic coordinate that specifies the north-south position of a point on the Earth's surface. Latitude is an angle which ranges from 0° at the Equator to 90° (North or South) at the poles. Longitude. Longitude (λ) is a geographic coordinate that specifies the east-west position of a point on the Earth's surface Google Maps is WGS84. It's just Digital Degrees instead of Degrees, Minutes, Seconds.

Use type() to determine whether a coordinate is a 2D coordinate (has latitude and longitude only) or 3D coordinate (has latitude, longitude and altitude). Use distanceTo() and azimuthTo() to calculate the distance and bearing between coordinates. The coordinate values should be specified using the WGS84 datum FlightGear uses a set of different coordinate systems to express geographic locations. All these coordinates are based on the WGS84 Ellipsoid.. Scenery layout, airports, runways, navaids, aircraft positions, and all that sort of stuff is all based on WGS84

By default, GPS receivers record data in latitude-longitude using the WGS84 (World Geodetic System 1984) datum (WGS84 is an earth fixed global reference frame, including an earth model. See http://www.wgs84.com/wgs84/wgs84.htm). Many GPS receivers allow the user to view their location in local coordinates as well (e.g., UTM, State Plane, etc.), performing a translation from WGS84 to the desired coordinate system (and datum) Summary. When originally defined, North American Datum 1983 (NAD 1983) and World Geodetic System 1984 (WGS 1984) were equivalent. In order to minimize coordinate changes, NAD 1983 is tied to the North American, Pacific (for Hawaii, Guam, etc.), and Marianas tectonic plates. WGS 1984 is tied to the International Terrestrial Reference System (ITRF).

A geodetic datum is a tool used to define the shape and size of the earth, as well as the reference point for the various coordinate systems used in mapping the earth. Throughout time, hundreds of different datums have been used - each one changing with the earth views of the times WGS84 frames are specifically named NAD83 (CORS96) and WGS84 (G1150). Thus, when the receiver tell us that the computed coordinates using GPS observations are referred to the WGS84, they actually mean WGS84(G1150). On the other hand, if we use CORS coordinates data, or the OPUS service, the NAD83 reference frame to which thes 1.WGS84 is the World Geodetic System or, more specifically, the most recent revision based on the version established in 1984. 2.European Terrestrial Reference System 1989 (ETRS89) is the geodetic reference frame utilized for the European areas. 3.WGS84's scope is worldwide while ETRS89 is limited to the European/Eurasian areas

The World Geodetic System of 1984 is the geographic coordinate system (the three-dimensional one) used by GPS to express locations on the earth. WGS84 is the defined coordinate system for GeoJSON, as longitude and latitude in decimal degrees. For the most part, when you describe a lon/lat coordinate location, it's based on the EPSG:4326. Lat/Long (DMS) - WGS84 eg N 52° 55.244 W 003° 58.438 or 53:04:49N 4:13:33W Generally most reliable to enter Degrees, Minutes, Seconds, using colons rather than symbols, eg 53°04'49.01N 4°13'33.0W as [ 53:04:49.01N 4:13:33.0W] If have Degrees and Decimal Minutes, just omit the seconds, eg [ 52:55.244N 3:58.438W Coordinate conversions between Swiss grid (CH1903) and WGS84 If you live in Switzerland or use Swiss maps, chances are that you have to deal with the Swiss grid (or Swiss coordinate system), which is a simple and practical coordinate system especially designed for this country
