Metrology is an expert application of survey and photogrammetric techniques for the determination of the shape and dimensions of 3D objects to the highest possible accuracy, and always with the most precise possible control of this accuracy.

For these purposes we make use of the most precise instruments and methods (ZEISS S10 electronic tacheometer (total station) guaranteeing distances to ± 1 mm and angles to ± 0.3 mgon, and ROLLEI d507 terrestrial photogrammetric camera) as well as procedures which allow the data collected to be processed with extremely high redundancy (overdetermination).
