A setting out device comprises a rod which can be supported at a target point in the area surrounding a point to be set out, a reflector which is arranged on the rod for tachymetric detection of the target point, a unit provided at the rod for transmitting information to and receiving information from a tachymeter, and an auxiliary setting out device which is arranged or can be arranged in a definite position in relation to the reflector for converting position correction information with respect to the point to be set out that was transmitted to the transmitting and receiving unit into a mark in the terrain representing the point to be set out. In this way, it is possible to set out possible projected points in the terrain within a short period of time and with great accuracy.

Setting out device

A geodetic instrument is disclosed which is set up over a ground point by a tripod and whose telescope is swivelable about a tilt axis and a rotational axis and which is outfitted with a laser arrangement for centering the rotational axis over the ground point and for determining the height h of the intersection point of the tilt axis and rotational axis over the ground point. In an instrument of the type mentioned above, a first, preferably collimated, laser beam extending in the rotational axis and at least one further laser beam path which extends divergent to the first laser beam are provided and, together, enclose an angle &ggr;, and wherein there is further provided a measuring device for determining the distance a between the two laser beam paths at the height of the ground point and an evaluating device for calculating the height h of the intersection point over the ground point from the relationship h&tilde;a.
