Abstract: A measuring system for marking a known target point in a coordinate system includes a mobile marking unit and a geodetic measuring device. The measuring device has a sighting unit, angle measurement functionality, and a camera for capturing a camera image. The measuring system has a database storing a target point position, an output unit that presents the camera image, and a control and processing unit. The measuring system has presentation functionality that presents a spatial deviation between the marking unit and target point positions on the output unit in first and second directions using, respectively, using first and second deviation displays. The first deviation display indicates a distance of the target point position from a plane defined by the measuring device and the marking unit. The second deviation display indicates a distance of the target point position from a normal to the plane defined by the marking unit position.

Abstract: Method for determining, with geodesic precision, the position of a target point on a target object by using a geodesic measuring device, said method comprising a sighting device which comprises at least one objective unit that defines an optical line of sight, an electronic distance measuring unit, and a thermal imaging camera for recording a thermal image in the direction of the optical line of sight.
