The high geometric objectivity characteristics entail that the reference system provide information on materials and details. As a result a two- fold description is required on the one hand the mea- surable geometry which in alignment with the scienti- fic idea method and the concept of space posited by Merleau-Ponty is exclusively referred to man and his work, and on the other hand real geometry which as claimed by Fermat is set in a specific historical process and is never fixed as an a priori and timeless category. It is, in fact, true that according to the way analogical information is perceived, used and communicated, the models do no longer simply prefigure but become data management systems capable of integrating hetero- geneous and fragmentary sources of information, of connecting different subjects/objects (private or pu- blic) and of governing an entire product lifecycle which in our case is referred to conservation and safeguard of a fortified structure, celebrates the god of war Khal- med at measurement investigations.
