Six Parameter

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

X Translation

dx

Y Translation

dy

Z Translation

dz

X Rotation

rx
