. Bertotti Scamozzi's prints are clearly a product of a measured 
survey; there are differences on minor details, 
. there is then a confrontation possible with today's measured 
drawings as shown in the illustration included, 
. the big question to be raised then is why and when the 
transformations occurred (the thermal window on the south 
facade has been closed, the vaulted hall at the ground floor 
has been radically changed to create a higher room at the first 
floor, ...). 
A manual has been written out and the technical procedures for a 
measured survey of a villa have been compiled. The priority, in 
logical and temporal terms, of measured drawings is stressed 
because of its irreplaceable function permitting the spatial location 
and representation of datums (historical information, quality of 
materials, stratification of layers, conservation state ...). 
Moreover we have suggested a further operation to implement the 
existing catalogue with a photogrammetrical campaign (facades, 
courtyards, arcades, decorated halls, ...) extended to the most 
significant villas. For those which will undergo a program of 
restoration a topographical campaign is absolutely necessary to 
support adequately the surveying. 
The quality and the quantity of informations that have been 
gathered, the necessity to record and to transmit not only the datas 
but also the drawings has advised us to have recourse to a CD- 
ROM.

different operations, the instruments used, 
. the topographic data: the network, the photogrammetric control 
points surveyed with multiple forward resection, the marked 
stations that establish the vertices of plano-altimetric network, 
field notes and sketches, 
. the photogrammetric data relative to front elevations: 
catalogued photographs, camera calibration certificate, 
orientation parameters, 
. numerical drawings of various floor plans (ground and first floor), 
significant sections (with integration of photogrammetry and 
measured survey), roof structure, structural details and 
ornamentation, 
. the program of digital photogrammetrical restitution 
(monoscopic and stereoscopic) using the orientation 
parameters (previously calculated and supplied by the CD- 
ROM) permitting the restitution of the parts that other scholars 
claim important in their research. 
This aspect offered by digital photogrammetry is particularly 
important to us: this experiment has attempted to underline the 
relationship between the representation of measured drawings and 
other investigations pertinent the studio of the architecture of a 
Venetian villa. Together with the representation of the survey work, 
with the architectural form of the building, there will be the pos- 
sibility to introduce new information, to develop closer a deeper 
architectural knowledge of the historical heritage.
