The technologies of architectural survey: A new comparison based on the Tower of Sotillo de la Ribera, Burgos

Abstract

The paper offers an original research about the analysis and the comparison of different techniques of survey concerning the architectural field – image-based and range-based – throughout the development of the theory of errors in order to evaluate reliability and precision of the results. In particular, this analysis will be focused on the tower of the parochial Church of Santa Águeda, a building located in the small village of Sotillo de la Ribera, within the province of Burgos (Spain). The first part of this work, therefore, has been submitted to the implementation of different methodologies, from the direct survey used as a basis, to the procedure to represent graphically the results (elevation, orthophoto and 3D model). The second phase, better illustrated here, deals with the validation of everything taken into account in order to evaluate the reliability and the precision of the graphics generated by means of traditional survey, photogrammetric survey and laser scanner.
