Figure 15. Examples of model texturing 
to free the operator (who does not have to be a photogrammetric 
specialist) from the limitation of reading information only on 
one plane, as happens using rectification images. The thematic 
representation, useful in conservation analysys and projects, can 
also be acquired directly by the conservator observing texturized 
model (Figure 15). 
4. CONCLUSION 
New tridimensional models can be useful for programs of 
conservation of the architectonic heritage. We have good hopes 
in to the future in which it will be possible to walk in a 3D space 
phases, following the reconstruction projects or to schedule the 
routine maintenance and simulating technical installation. Since 
many years the member of this local research pool are involved 
in problems concerning the analysis and metric survey of ancient 
architecture and archaeological fields. Recently we were involved 
in laser scanner evaluation, both for image communication and for 
metric precision. It is too early to make statements about this work: 
we are still completing the model. Our purposes are: to complete 
the apse modeling from photogrammetric and topographic data and 
to merge it with the transept model; to combine stratigraphy data 
with 3D model; to navigate our site in 3D and to be able to replay 
the constructive phases as they proceeded through different time.
