4 - PROSPECTS OF APPLICATION IN THE CATALOGUING 
OF THE IMAGES PROJECTED ON THREE-DIMENSIONAL 
SURFACES 
The high number of takens and the fragmentation of 
the acquisition of the images (made by a sequence 
of pictures of the surfaces of the building, of 
the mosaics, of the bas-rilieves and of frescos) 
ask that the phase of survey could be made with 
instrumentations of big handiness. 
In particular it is needed an organic project of 
memorization, organization of archives in the way 
that could satisfied the needs of cataloguing and 
fast consultation. 
The images are acquired in different sequences 
depending on the purposes. It is as a film 
reassembled in different histories 
At the end of the cataloguing it becomes important 
to think at a spatial collocation where to put the 
images: it means to locate the images in the 
recreated space of the building (Brumana,1991). In 
this case the three-dimensional aspect involes not 
only the single image, that can be imagined, for a 
moment, bidimensional: for example the internal 
images of a Basilica must located on the 
corresponding surfaces (the domes images on the 
domes, the images of the floor on the floor...) in 
the way to dress all the body of the church. This 
operation corresponds in technical terms to a 
projection made with a number of images. 
A catalouguing directly based on the geometry of 
the object should permit a well done organization, 
directly reachable by the great number of 
utilizers in function of the position. It sholud 
also permit an interesting connection and 
investigation between the cognitive levels. 
The St.Marcus' Basilica is now referred in all its 
surveies to the National Geographic system. A GIS 
will allow in the future the availability of the 
monument in its whole.
