Abstract: A total station including an electro-optical distance measuring unit and a scanning functionality is disclosed. The total station may include an analysis unit for analysis of the registered measuring signal data and conversion thereof into scanning points for a point cloud, whereby a point cloud having the scanning points can be generated. The distance measuring unit may be configured in such a manner that the distance measurement can be carried out by means of runtime measurement and/or waveform digitizing (WFD). In addition, the total station may have a program storage unit which may provide at least two scanning modes, wherein the at least two scanning modes differ at least in a measuring rate such as, for example, in the number of scanning points per unit of time.

Abstract: A method comprising: setting up a stationary surveying device at a first known positioning in a surrounding area of the object; retrieving from a memory a set of object points of an object to be surveyed and/or to be marked; surveying and/or marking from a first positioning object points of the set of object points that can be surveyed and/or can be marked from the first positioning by means of the free beam, on the basis of a target direction; ascertaining missing object points of a set of object points; relocating the surveying device to a second, unknown positioning in the surrounding area of the object; automatically determining a second positioning by the surveying device on the basis of the knowledge of the first positioning, so that the second positioning is known; surveying and/or marking missing object points by means of the free beam from the second positioning.
