A geodatic surveying device which is equipped with an automatic target point sighting functionality for determining the position of a target point. A reticle pattern that corresponds to the outer shape of the known reticle is stored, wherein a main point of the reticle pattern is predefined as indicating the target point. In order to carry out an automatic target point sighting functionality, the evaluation means are designed such that, after the function start, a camera image of the reticle is automatically recorded, the reticle pattern is aligned with the reticle in the camera image by means of image processing and, depending on a position of the main point in the camera image in the matched state of the reticle pattern, the orientation of the sighting apparatus is changed in a motorized manner such that the optical target axis OA is oriented with high precision at the target point.

An augmented-reality system is combined with a surveying system to make measurement and/or layout at a construction site more efficient. A reflector can be mounted to a wearable device having an augmented-reality system. A total station can be used to track a reflector, and truth can be transferred to the wearable device while an obstruction is between the total station and the reflector. Further, a target can be used to orient a local map of a wearable device to an environment based on a distance between the target and the wearable device.
