Abstract
Some embodiments of the invention relate to a method for determining the position data of a geodesic surveying instrument by comparing of a reference data set extracted from data of an image of the surroundings of the surveying instrument position with position-referenced data sets which consists of data of a corresponding type, and determining the position data using the position reference of the selected position-referenced data set that has a comparatively important level of match with the reference data set.

18. A method for determining the position data of a geodetic surveying instrument, wherein the method comprises:
-
recording an image of the environment of at least one contiguous region of the environment of the surveying instrument position to be determined, providing a multiplicity of stored position-referenced volumes of data from position-referenced data records, extracting a reference volume of data consisting of read or derived data of one image of the environment by means of image processing, wherein each position-referenced volume of data and the reference volume of data have data of corresponding type, collating the reference volume of data with the provided position-referenced volumes of data with identification of matches between reference volume of data and a respective individual position-referenced volume of data, selecting that position-referenced volume of data that has a comparatively significant degree of match with the reference volume of data, ascertaining the position data of the surveying instrument position on the basis of position reference of the selected position-referenced volume of data. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41)
