PHOTOGRAMMETRY AND SURVEY PROCEDURES FOR THE ANALYSIS OF VENETIAN VILLAS: THE CASE STUDY OF VILLA ZENO BY ANDREA PALLADIO

摘要

one of the most significant aspects of the architectural heritage of the Veneto region is the Venetian Villa. This project originates from the necessity of standardization which will regulate techniques and adjust procedures in order to analyse and catalogue their preservation. Different approaches are necessary for the comprehension of a historical building and the measured survey is essential for two particular reasons - the first being the knowledge of the building's composition, its geometry, its proportions; the second being the possibility for the spatial location and representation of datums (historical information, building materials, stratification of layers, quality of conservation ...). Measured survey is therefore contemporarely the representation of the material text of the villa and the most adequate support for the informations acquired through different investigations and various analytical techniques. The primary objective is to establish a vade-mecum for a project planning of the operations to be repeated for all villas, a preliminary standard support for different successive specific examinations. The mean with which all information have been catalogued is through the CD-ROM (an instrument suitable for the integration of scholarly programs of investigation) where the technical report of the survey work can be found with all the topographical and the photogrammetrical datas, the program of digital photogrammetrical restitution (monoscopic and stereoscopic) using the orientation parameters (supplied by the CD-ROM) permitting the restitution of those elements that other scholars claim important in their research.
