Based on the Helmert family of transformations, the Six Parameter transformation is very similar to a Seven Parameter CFR transformation, except it does not contain a scale parameter. This shift also uses a more rigorous variation that does not require the rotation angles to be small to achieve accurate results.
The "SixParameter" DatumShift has the following Parameters:
|
Parameter Name |
Parameter String |
Units |

Y Translation |
dy |
|
|
Z Translation |
dz |
|
|
X Rotation |
rx |
|
|
Y Rotation |
ry |
|
|
Z Rotation |
rz |
