Abstract
In laser surveying system has a laser measuring unit which is operable independently of a laser projector, a laser spot pattern is first determined by using the laser measuring unit and projected onto the working face of an object structure by driving the laser projector. While marking the working face with the laser spot pattern formed by the laser projector to execute the desired construction work, the laser measuring unit is turned toward a different measuring object so as to independently make other measurements. Thus, point marking and measurement on different objects can be rationally effected at one time.
