2. Description of the Related Art In a surveying work, for example, when a road or a residential land development is designed, there is a work called "measurement setting" for staking a position on a drawing to be a new road on the site. This surveying work is a very important task that is indispensable for survey design work and is frequently performed, but conventionally, it has been performed almost manually.

[0003] Such a total station (TS)
To explain an example of the conventional measurement work using
A TS is set at a first reference point (M1) called an “instrument point”, and the TS is collimated in a direction of a second reference point (M2) called a “back view point” and is referred to as a “measuring point”. The surveying work is performed by driving a pile into one or a plurality of predetermined coordinate positions (Tn). In order to determine this surveying point, the coordinates from the instrument point (M1), the rear viewpoint (M2) and the surveying point (Tn) are used to determine the direction from the instrument point (M1) to the rear viewpoint (M2). On the other hand, an angle ∠M2-M1-Tn (referred to as an “inner angle”) formed by the direction from the instrument point (M1) to the measurement point (Tn) is calculated, and the TS is manually turned to the inner angle. Thereafter, the person with the prism moves to the front of the TS and starts measuring the distance. The prism is moved back and forth until the measured distance becomes a predetermined distance between points (between M1 and Tn), and the pile is driven when the distance is matched.

In recent years, work has often been performed using a combination of an electronic field note (also referred to as a “data recorder”) and a TS. However, the TS is very delicate to adjust the measurement angle of the TS. In order to operate in a timely manner, considerable techniques were required, and the accuracy and time tended to vary depending on the observer. In addition, when the prism moves, the speed of the work to follow and collimate it is required, and the direction with the remaining distance is given to the person with the prism, and the person with the prism Personal experience and intuition, such as how much distance to move to the target measuring point after moving in the direction of, greatly affects the efficiency of work.
