continues to Determine Scale .
For Onestep and Twostep only.
The scale is calculated using the formula (r + h)/r where
r
is the distance from the centre of the ellipsoid to the WGS 1984 point
selected in Choose Common Point , and
h is the height of this point above the WGS 1984 ellipsoid.
Key Description
OK To confirm the selections and to continue with the subse-
quent panel.
Grid Available Twostep and for Method: Combined scale factor .
To compute the grid scale factor. Refer to "39.4.3 Computing
the Grid Scale Factor".
Height Available Twostep and for Method: Combined scale factor .
To compute the height scale factor. Refer to "39.4.4 Comput-
ing the Height Scale Factor".
Scale or
Ppm
To switch between displaying the true scale and displaying
the ppm.
Meas app To measure a point and store it in Job where WGS84 points
are stored . Method: Convergence angle when WGS84
point is highlighted.
