Step 5: Determine Scale
This screen contains different fields, depending on the <Method:> selected. The explana-
tions for the softkeys given below are valid as indicated. The scale is calculated using the
formula (r + h)/r where r is the radius of the ellipsoid at the position of the WGS 1984 point
selected in DET C SYS Step 3: Choose Common Point and h is the height of this point
above the local ellipsoid.
