The Molodensky-Badekas transformation changes coordinates from one reference frame to another by means of a 10-parameter shift. The Molodensky-Badekas transformation is a variation of the Helmert transform where the rotational terms are not directly applied to the ECEF coordinates, but on cartesian coordinates relative to a reference point (usually close to Earth surface, and to the area of use of the transformation). When px = py = pz = 0, this is equivalent to a 7-parameter Helmert transformation.
- Input Coordinates : Enter cartesian coordinates. Use Comma-separated values, and enter one coordinate per line. Supports input of multiple lines. The cartesian coordinates format is X , Y , Z, The unit is meters(m).
Convention : Indicates the convention to express the rotational terms when a 3D-Helmert /
7-parameter more transform is involved.
The two conventions are equally popular and a frequent source of confusion. The coordinate frame convention is also described as an clockwise rotation of the coordinate frame. It corresponds to EPSG method code 1034 (in the geocentric domain) or 9636 (in the geographic domain) The position vector convention is also described as an anticlockwise (counter-clockwise) rotation of the coordinate frame. It corresponds to as EPSG method code 1061 (in the geocentric domain) or 1063 (in the geographic domain).
The result obtained with parameters specified in a given convention can be obtained in the other convention by negating the rotational parameters (rx, ry, rz)
