Java library for converting OSGB (Ordnance Survey National Grid) references and standard Latitude-Longitude (WGS84) coordinates.
The following examples, taken from the unit tests, show how to use the library. For more example, refer to the unit tests.
double[] latlon = OSGB36.fromWGS84(51.5085300, -0.1257400);
//latlon[0] = 51.508019, latlon[1] = -0.1241133
double[] latlon = OSGB36.toWGS84(51.5, 0.116667);
//latlon[0] = 51.500514, latlon[1] = 0.115033
//Convert to Easting and Northing
double[] eastingNorthing = NationalGrid.fromNationalGrid("NW 16234 34223");
//Convert from Easting and Northing into Cartesian Coordinates (LatLon)
double[] latlonOSGB38 = EastingNorthingConversion.toLatLon(
eastingNorthing,
Constants.ELLIPSOID_AIRY1830_MAJORAXIS,
Constants.ELLIPSOID_AIRY1830_MINORAXIS,
Constants.NATIONALGRID_N0,
Constants.NATIONALGRID_E0,
Constants.NATIONALGRID_F0,
Constants.NATIONALGRID_LAT0,
Constants.NATIONALGRID_LON0);
//Convert from LatLon (OSGB) to WGS84
double[] latlonWGS84 = OSGB36.toWGS84(latlonOSGB38[0], latlonOSGB38[1]);
