Creating an Observation by Angle and Distance

Product Documentation

View Original

Use the angle distance (AD) command to quickly create a point by angle and distance.

Create a point using an angle turned from either a specified reference line or a previously determined backsight point. You can also use a vertical angle or vertical distance to locate the point.

Note

For parameter descriptions, see the Quick Reference tab.

To create an observation by angle and distance, using the command language

  1. In Toolspace, on the Survey tab, right-click the network that you want to add points to, and click Survey Command Window.
  2. At the Command line, enter:

    AD (point) [angle] [distance] (description)

To create an observation by angle, distance, and vertical angle, using the command language

  1. In Toolspace, on the Survey tab, right-click the network that you want to add points to, and click Survey Command Window.
  2. At the Command line, enter:

    AD VA (point) [angle] [distance] [vertical angle] (description)

To create an observation by angle, distance, and vertical distance, using the command language

  2. At the Command line, enter:

    AD VD (point) [angle] [distance] [vertical distance] (description)

Examples

This example creates point 103, which is located by turning a horizontal angle of 80°20'40" right at a distance of 100 units from the instrument point with the description WELL. Because no method of vertical difference determination was given, the elevation is <Null>.

AD 103 80.2040 100 WELL

This example creates point 101, which is located by turning a horizontal angle of 100°20'45" right from the backsight and using a vertical angle of 91°15'15" at a distance of 100 units from the instrument point with the description IP.

AD VA 101 100.2045 100 91.1515 IP

This example creates point 102, which is located by turning a horizontal angle of 90°30'30" right from the backsight and using a vertical distance of -1.5 units at a distance of 200 units from the instrument point with the description EL.

AD VD 102 90.3030 200 -1.5 EL

Points created with the angle distance command:

Point 101 is located by turning a horizontal angle of 100°20'45" right from the backsight and using a vertical angle of 91°15'15" at a distance of 100 units from the instrument point with the description IP.

Point 102 is located by turning a horizontal angle of 90°30'30" right from the backsight and using a vertical distance of -1.5 units at a distance of 200 units from the instrument point with the description EL.

Point 103 is located by turning a horizontal angle of 80°20'40" right at a distance of 100 units from the instrument point with the description WELL. Because no method of vertical difference determination was given, the elevation is <Null>.
