Compute azimuth

You can compute an azimuth using keyed‑in data or points stored in the job and store the results in the job.

  1. To open the Compute azimuth form, do one of the following:
    • Tap and select Cogo / Compute azimuth.
    • From the calculator, tap Azimuth.

  2. Calculate an azimuth using one of the methods below.

    1. In the Method field, select Between two points.

    2. Select the From point (1) and the To point (2).

      The software calculates the azimuth between the entered values (3).

    3. Tap Store.

    You can compute an azimuth from two points in the job directly in an azimuth field. To do this, enter the point names in the Azimuth field, separated by a hyphen. For example, to compute the azimuth from point 2 to point 3, enter "2–3". This method works with most alphanumeric point names, but it does not support point names that already contain a hyphen.

    1. In the Method field, select Bisected azimuths.

    2. Enter values for Azimuth 1 (1), and Azimuth 2 (2).

      The software calculates the following values: the azimuth halfway between the entered values (3) and the computed angle, measured clockwise between azimuth 1, and azimuth 2.

    3. Tap Store.
    1. In the Method field, select Bisected corner.

    2. Select the Side point 1 (1), Corner point (3), and Side point 2 (2).

      The software calculates the following values:

      • azimuth (4), halfway between Side point 1 and Side point 2, from the Corner point
      • inside angle (5) and outside angle (6)
      • distance from the corner point to the two side points and the distance from one side point to the other
      • azimuth from the corner point to the two side points
      • angle between the corner point and each side point, as well as the opposite angle (7)
    3. Tap Store.
    1. In the Method field, select Azimuth plus angle.

    2. Enter the Azimuth (1) and the Turned angle (2).

      The software calculates the sum of the two values (3).

    3. Tap Store.
    1. In the Method field, select Azimuth to line offset.

    2. Select the line (1), and enter the station (2) and the horizontal offset (3).

      If the line does not already exist, tap and select Two points. Enter the start point and end point to define the line.

      The software calculates the following values: computed azimuth (4), from the start point of the line to the offset point, and the computed angle, measured clockwise between the line and the azimuth (4).

    3. Tap Store.

  3. When selecting reference points, select them from the map or tap for other selection methods. See To enter a point name.

    You can enter data in different units. For example, you can add an angle in degrees to an angle in radians, the answer is returned in the format you specified in the job properties.
