Abstract
The invention relates to a method for measuring tracks in relation to a measuring plan of the track which contains the actual position of the track, in relation to an absolute coordinate system. A measuring platform () is guided along the track (), whereon an inertia platform () is arranged, which is initialised, respectively, calibrated to the beginning of the measurement and is aligned in relation to the coordinate system. The inertia platform () detects the respective positions of the measuring platform () in relation to the coordinate system during the journey of the measuring platform (). Positional data of the inertia platform () is periodically examined based on fixed points (') which are arranged in the vicinity of the track and deviations in relation to the coordinate system are corrected by novel calibration, respectively, alignment.
