Abstract
A survey system including a target unit that has a survey stick having a high-precision localizable target and a hand-held remote control unit. The remote control unit has an electronic graphical display and can be mounted on a holder on the survey stick such that the remote control unit is in a fixed position relative to the target fitted to the survey stick. The remote control comprises a camera for taking a camera image in a defined shooting direction. In addition, an image processing and evaluation unit with a data link to the position-finding unit and to the camera is provided which, from knowledge of the fixed relative position and of a defined shooting direction and also on the basis of the determined target position, can spatially relate image data from the camera to the targets in the coordinate system.
