To Create a Survey Observation by Angle and Distance

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.

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)

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>.

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

or

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

or

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

Parameter	Definition
point	The assigned point identifier. You do not need to assign a point number if auto point numbering is on.
angle	The measured horizontal angle. It is assumed to be clockwise (right). Use a negative number (-) to turn counter-clockwise (left). Express in the current units (Degrees Minutes Seconds (D.MS), grads, decimal degrees (D.DD), radians, or mils).
distance	The distance from the instrument point to the point being located. It is measured in the current units unless otherwise specified. Distance is assumed to be a horizontal distance unless VA is used. When VA is used, the distance is recognized as slope distance.
vertical angle	The direction of the vertical angle (zenith, horizontal, or nadir). Specify the vertical angle in the current angular units.
vertical distance	The elevation difference from the instrument to the prism. If the prism is higher than the instrument, then this is a positive value.
description	An optional description associated with the point.
