ABSTRACT:
The invention relates to an arrangement for setting out terrain points and straight lines comprising a tacheometer which emits a measuring beam and detects the same after reflection at a reflector, a means for interrupting the measuring beam which is intended to mark the place of the terrain point to be set out, a target at the same place, displaceable at least at right angles to the measuring beam, and means for indicating the position of the means for interrupting the beam relative to the latter. By virtue of the arrangement the operator setting out the terrain point is able to accomplish the task without the aid of the tacheometer operator.
