4. Geometric Documentation of Monuments  The geometric documentation of a monument is the procedure of acquiring, processing, presenting, archiving, storing and managing of data (nowadays mostly digital) adequate to determine the position, the true form, shape and size of the monument in the 3D space at a given moment in time.  The geometric documentation of monuments records their present, as this has evolved through time and provides the necessary base material for those who study their past as well as for those who take care of their future.
