1. A method for operating a piste grooming vehicle having at least one piste grooming device for preparing a piste, comprising the steps of:
detecting an actual topography of a piste section, positioned in front of the piste grooming vehicle in a forward travel direction thereof, of the piste, the step of detecting an actual topography including:
detecting coordinates of the actual topography with respect to a local vehicle coordinate system assigned to the piste grooming vehicle;
detecting a location, with a GPS location system, and a position, with a position measuring unit, of the piste grooming vehicle and therefore of the local vehicle coordinate system with respect to a global reference coordinate system, the position measuring unit measuring a longitudinal inclination and/or a transverse inclination of the piste grooming vehicle; and
transforming the detected coordinates of the actual topography into the global reference coordinate system as a function of the detected location and the detected position of the local vehicle coordinate system;
determining at least one differential value between the transformed coordinates of the actual topography and coordinates of a reference topography of the piste, the coordinates of the reference topography being based on the global reference coordinate system, to determine an actual topography of the piste section with respect to the global reference coordinate system; and
actuating the at least one piste grooming device in accordance with the at least one determined differential value.
