CLOSE-RANGE PHOTOGRAMMETRY PRACTICE: GRAPHIC DOCUMENTATION of the INTERIOR of the WALLS of AVILA (Spain)

Abstract

This work presents the results of the photogrammetric survey of the inner side of the walls of Avila. The graphical restitution realized is part of the studies for the Master Plan of the walls of Avila promoted by the Cultural Heritage Institute (IPCE), under the Spanish Ministry of Education, Culture and Sport in 2017. The monument has been extensively drawn throughout history, but there isn't a complete and detailed planimetric documentation of its whole extent. The huge dimensions of the walls and the different conditions of the visible sectors of the interior side were difficult conditions to overcome. The versatility and great accuracy of photogrammetric method allowed the reconstruction of the interior of the walls in a short time and with accurate results . Moreover the possibility of integrating the results with previous surveys made it possible to present a complete and coherent documentation of the walls. This is an important point and in the research a continuity is sought between restitutions carried out with tools and at different times. In addition, a series of considerations are advanced about the transformation of traditional methods of representation of architectural heritage.
