1. A method for determining position data (2) of a geodetic surveying instrument (50) by:

  • recording an environment image (1,9,11,12) of at least one contiguous region of the environment of the surveying instrument position (P) to be determined,providing various stored position-reference data volumes (4,13,14,15,22c) from the position-reference data records,extracting, by image processing, a reference data volume (22b,35) formed by read or derived data of one environment image (1,9,11,12), wherein the respective position reference data volume (4,13,14,15,22c) and the reference data volume (22b,35) have corresponding types of data (D1a, D1b, D2a-D2D, D3a-D3e, D4a-D4e,40),-in the case of a match between an identification reference data volume (22b,35) and the respective position reference data volume (4,13,14,15,22c), the reference data volume (22b,35) is surveyed (3) using the provided position reference data volumes (4,13,14,15,22c),-selecting (7) a position reference data volume (4,13,14,15,22c) having a relatively significant degree of matching with said reference data volume (22b,35),-determining (8) position data (2) of the surveying instrument position (P) based on a position reference (5) of the selected position reference data volume (4,13,14,15,22c), the position data (2) of the surveying instrument position (P) being determined as known absolute position data of actual or calculated recording locations associated with the selected position reference data volume (4,13,14,15,22 c).
