Further, in the surveying system according to the present invention, the portable computer is provided with operating means for instructing the automatic tracking type distance measuring and angle measuring instrument to operate.

Further, the surveying system according to the present invention provides an operation instruction for directing the automatic tracking type distance measuring instrument to a desired desired known point selected from the known points stored in the storage means. The operating means is configured so as to be able to perform.

In the surveying system according to the present invention, a desired surveying scheduled point is superimposed and displayed on the screen display means.

In the surveying system according to the present invention, a technician carrying a portable computer tracks the target with an automatic tracking distance measuring and angle measuring instrument while carrying the target. Then, the portable computer receives the measurement data of the target position measured by the automatic tracking type distance measuring angle measuring instrument via the measuring-side transceiver and the operating-side transceiver, and stores the data in the storage means. The current position of the target and its movement locus are displayed on the screen display means using the data.

In this way, the surveying engineer
By looking at the screen display means, it is possible to grasp the survey result accurately and in real time while always checking where you are, and also to perform surveying alone by a technician without the need for an assistant as in the past It can be performed.

The automatic tracking type distance measuring and angle measuring instrument includes an automatic tracking type total station, an automatic tracking type transit, and the like. The format of the portable computer is arbitrary, and can be appropriately selected from a notebook computer, a pen-input computer, a touch panel computer, and the like.

The movement trajectory of the target may be displayed as discontinuous data consisting of only the data of the actually measured points, or the coordinates of the unmeasured points may be obtained by using the coordinate data of the measured known points. It may be determined by an interpolation process or the like and displayed as a continuous curve.

When the measurement is performed by the automatic tracking type distance measuring and angle measuring instrument, the measurement is automatically performed at time intervals set on the instrument side, and the measured data is similarly transferred to the portable computer. It may be performed automatically, but if the portable computer is provided with operating means for instructing the operation of the automatic tracking type distance measuring instrument, the automatic tracking type distance measuring and measuring apparatus can be operated by operating the operating means. By giving an operation instruction to the angular instrument, the technician can cause the automatic tracking distance measuring angular instrument to measure the target position, transfer the measurement data, record the measurement data, and the like at a convenient timing.

In particular, when the automatic tracking type distance measuring and measuring instrument loses a target, that is, when a mirror lost (prism lost) occurs, the automatic tracking type distance measuring and measuring instrument is swung up, down, left and right by remote operation. To recapture the target.

Here, the operation means is provided so that an operation instruction to direct the automatic tracking type distance measuring and angle measuring instrument to a selected desired known point among the known points stored in the storage means can be given. With this configuration, even when a mirror is lost in the automatic tracking distance measuring and measuring instrument, a target is set on the selected known point, and in this state, the automatic tracking distance measuring and measuring instrument is directed to the known point. By allowing the target, the target can be surely recaptured.

If the desired surveying point is displayed on the screen display means in a superimposed manner, a technician who conducts surveying with the target can display the intended surveying point displayed on the screen displaying means and his own. It is possible to surely move to the next surveying point while checking the position.
