Computing Required Azimuth

Available for:
One Point Localisation method with Onestep or Twostep transformation.
•
Method: Two WGS84 points and Method: User entered in Determine
•
Rotation.
Allows two local points to be chosen from local job between which the
required azimuth is computed. This azimuth is then used with an azimuth com-
puted between two WGS 1984 points chosen from the WGS84 job to calculate
the rotation of the transformation.
The computed required azimuth appears in the Required azimuth field for
Method: Two WGS84 points and the Rotation field for Method: User
entered in Determine Rotation.
Press Inverse in Determine Rotation.

Computing the Grid Scale Factor

For One Step Localisation method with Twostep transformation. Calculates the
grid scale factor. The grid scale factor is the scale factor of the point chosen,
relative to the projection being used.
Description
The point ID of the first known point for the
azimuth calculation.
The point ID of the second known point for
the azimuth calculation.
