Compute azimuth step-

Determine Coordinate System - One Point Localisa-

Computing Required Azimuth

Available for <Method: Two WGS84 Points> and <Method: User Entered> in DET C SYS

Step 4: Determine Rotation.

Allows two local points to be chosen from <Local Pts Job:> selected in DET C SYS Deter-

mine Coord System Begin between which the required azimuth will be computed. This

azimuth is then used with an azimuth computed between two WGS 1984 points chosen from

<WGS84 Pts Job:> selected in DET C SYS Determine Coord System Begin, to calculate

the rotation of the transformation.

The computed required azimuth appears in the <Reqd Azimuth:> field for <Method: Two

WGS84 Points> and the <Rotation:> field for <Method: User Entered> in DET C SYS

Step 4: Determine Rotation.

Refer to "39.1 Accessing Determine Coordinate System - One Point Localisation"

to access DET C SYS Step 1: Choose Transform Type.

Select <Transfrm Type: Onestep> or <Transfrm Type: Twostep>.

Continue to DET C SYS Step 4: Determine Rotation.

Select <Method: Two WGS84 Points> or <Method: User Entered>.

INV (F2) to access DET C SYS Compute Required Azimuth.

DET C SYS Compute Required Azimuth

<From:> The point ID of the first known point for the azimuth calculation.

<To:> The point ID of the second known point for the azimuth calculation.

Select the points stored in the <Local Pts Job:>.
