CONSTRUCTION SITE REFERENCING

The invention relates to a method of automated spatial worksite referencing of a networked electronic measuring device, which has awareness of a rough location information of itself at a worksite location. It does so with querying a database for construction plan information about the rough location and its vicinity and about an actual work progress. Thereof an actual-state nominal spatial information at the rough location and its vicinity is computed. According to the invention, an automatically determining of a fine location information of the networked electronic measuring device at the worksite location, is done by at least one iteration of: automatically determining a measurement point in the vicinity and measuring the measurement point by the networked electronic measuring devices measurement functionality, and then automatically assimilating the measurement point to the actual-state nominal spatial information and thereby determining the fine location information. When a desired level of ambiguity and/or accuracy of the determined fine location is not reached, do another iteration with another additional measurement point, or else, automatically derive the fine location information as spatial reference of the networked electronic measuring device with respect to the worksite location.
