Use the following equation to calculate the HeightField Scale:

   Scale = (DataMax - DataMin) / (0.5 * sqrt((xMax-xMin)^2 + (yMax-yMin)^2))

To adjust for the offset of the DataMin value, insert a Transform module between the Gridder output and the HeightField input and offset the Z axis by the DataMin value.


Terminology note: DataMax and DataMin are referring to Zmax and Zmin

See attached Excel file for an example of the equation.
