Use the stadia rod intercept method to reduce a distance that has been measured.

STADIA (point) [angle] [distance] [rod] (vertical angle) (description)
| Parameter | Definition |
|---|---|
| point | The point identifier of the new point. 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). Type the angle in the current units (DMS, grads, decimal degrees, 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. The distance is assumed to be a horizontal distance unless a vertical angle is specified. When a vertical angle is specified, the distance is recognized as a slope distance. The distance required here is actually the rod intercept multiplied by the stadia constant. For example, if 1.37 is intercepted on the stadia board, and the stadia constant is 100, then you should type 137 as the distance. |
| rod | The rod reading taken by the central hairline of the instrument. This is, in effect, the height above ground of the sighted target point. |
| vertical angle | The direction of the vertical angle to the rod (zenith, horizontal, or nadir) and must be specified in the current angular units. |
| description | An optional description associated with the point. |
