A method of automated spatial worksite referencing of a networked electronic measuring device, with: ∘ ascertaining a rough location information of the networked electronic measuring device at a worksite location (4,21), ∘ querying a database stored at a server means for construction plan information about the rough location and its vicinity and ∘ querying the database for an actual work progress with respect to a construction process, ∘ computing an actual-state nominal spatial information at the rough location and its vicinity based on the construction plan information and the actual work progress and ∘ automatically determining a fine location information of the networked electronic measuring device at the worksite location (4,21), by at least one iteration of • automatically determining a measurement point in the vicinity, preferably wherein said point allows for reducing ambiguities and/or increasing accuracy of the fine location information, • measuring the measurement point by the networked electronic measuring devices' measurement functionality, • automatically assimilating the measurement point to the actual-state nominal spatial information and determining the fine location information of the networked electronic measuring device thereof, and ∘when a desired level of ambiguity and/or accuracy of the determined fine location information is not reached, determine, measure and assimilate an additional measurement point in an additional iteration, and ∘when the desired level of ambiguity and/or accuracy is reached, automatically derive the fine location information as spatial reference of the networked electronic measuring device with respect to the worksite location, preferably including providing of the fine location information for further worksite tasks. ∘ ascertaining a rough location information of the networked electronic measuring device at a worksite location (4,21), ∘ querying a database stored at a server means for construction plan information about the rough location and its vicinity and ∘ querying the database for an actual work progress with respect to a construction process, ∘ computing an actual-state nominal spatial information at the rough location and its vicinity based on the construction plan information and the actual work progress and ∘ automatically determining a fine location information of the networked electronic measuring device at the worksite location (4,21), by at least one iteration of • automatically determining a measurement point in the vicinity, preferably wherein said point allows for reducing ambiguities and/or increasing accuracy of the fine location information, • measuring the measurement point by the networked electronic measuring devices' measurement functionality, • automatically assimilating the measurement point to the actual-state nominal spatial information and determining the fine location information of the networked electronic measuring device thereof, and • automatically determining a measurement point in the vicinity, preferably wherein said point allows for reducing ambiguities and/or increasing accuracy of the fine location information, • measuring the measurement point by the networked electronic measuring devices' measurement functionality, • automatically assimilating the measurement point to the actual-state nominal spatial information and determining the fine location information of the networked electronic measuring device thereof, and ∘when a desired level of ambiguity and/or accuracy of the determined fine location information is not reached, determine, measure and assimilate an additional measurement point in an additional iteration, and ∘when the desired level of ambiguity and/or accuracy is reached, automatically derive the fine location information as spatial reference of the networked electronic measuring device with respect to the worksite location, preferably including providing of the fine location information for further worksite tasks.
