Converts ECEF Cartesian coordinates back to geodetic WGS84 latitude/longitude/height using Bowring's method.
Worked example
ECEF point. Returns the matching latitude, longitude and ellipsoidal height.
Frequently asked questions
Is the height ellipsoidal or above sea level?
Ellipsoidal (above the WGS84 ellipsoid). Use the orthometric-height converter to get height above mean sea level.
