Metrology

Metrology is about highly accurate measurements for construction and engineering purposes. Where accuracies in traditional land surveying and topography are often on the mm to cm level and in marine surveying and bathymetry on the dm to m level, metrology brings those accuracies down to sub-millimeter level to allow constructions to be accurately engineered. An example underwater is the spool piece connection between a pipeline and a subsea platform or riser. 

Techniques used in metrology are often derived from standard techniques such as underwater acoustics positioning, total stations and level instruments but use versions that are more accurate or have measuring procedures that surpass those used in general surveying.
