Expand description

7-parameter Helmert (Bursa-Wolf) transformation parameters.

Defines the transformation from one datum to WGS84 geocentric coordinates:

[X']   [dx]         [  1  -rz   ry] [X]
[Y'] = [dy] + (1+ds)[  rz   1  -rx] [Y]
[Z']   [dz]         [ -ry  rx   1 ] [Z]

Fields§

§dx: f64

X-axis translation in meters.

§dy: f64

Y-axis translation in meters.

§dz: f64

Z-axis translation in meters.

§rx: f64

X-axis rotation in arc-seconds.

§ry: f64

Y-axis rotation in arc-seconds.

§rz: f64

Z-axis rotation in arc-seconds.

§ds: f64

Scale difference in parts-per-million (ppm).
