The capacities expressed by the new systems of data acquisition also have a spin-off for the archaeological field, not only for objects of great dimensions, but above all for objects of small height in which the accuracy of the datum accuracy allows hints for new types of detail analysis.
Through the combination in the use of some software, often coming from different fields of application, we can think about laser scanning as a base on which to make a series of direct and indirect derivation data meet that is. Both a series of data proper to the analyzed object (e.g. the texturization and the simulation of optoelettroncs behaviors) and data derived from the study of the same object.
If from one side it is therefore interesting to be able to submit the single object to a detail analysis, impossibile up to yesterday, the most important spin-off from the scientific point of view is felt in the use of this study on a great deal of analogous finds in a systematic way.
From here the possibility to develop typological analyses also substantialized by a metrological analysis supported by the precision of the numerical datum.
The further benefit of an investment in such a search of this type is the ability to represent the analyzed objects in a dynamic and interactive way allowing both a more expeditious analysis from the experts of the sector also for objects characterized by a complex morphology and for a more immediate and comprehensible popular fruition for the vast public of non-attachés, too.
Therefore, the online popularization of VRML models and STL files allows both an interactive consultation, and also the possibility to stimulate the diffusion of the datum aside from its geographical position and its state of maintenance.
