Cycles and trends in the dynamics of a leaning tower. Eight years of geometric monitoring with surveying techniques

DOI: 10.7764/RDLC.16.1.158 This paper presents the methodology and results of the geometric monitoring of a leaning tower (Santa Maria la Blanca church in Agoncillo, La Rioja, Spain) with surveying techniques. Throughout the period 2007-2014, two types of variations in the geometry of the building have been tracked: those due to a seasonal cycle (winter-summer) and those caused by the progressive increase in the leaning of the tower. The text describes the distribution of the control points, the fieldwork, the computation strategy and the way to ensure that the results are significant. By way of conclusion, this work discusses the applicability of these techniques to the monitoring of historic buildings.

El modelo 3D como base para la documentación y difusión de los elementos patrimoniales. Aplicación al mausoleo romano denominado ‘la Sinagoga’ de Sádaba (Zaragoza, España).

A case study of a project for the geometric documentation of a roman mausoleum from the 4th century is used as the overarching element in order to put forward a reflection on some of the steps for the process of documentation itself, as well as on the utility of the outcomes. The main issues considered are: (1) documentation project, (2) three-dimensional modeling, (3) use of different kinds of two-dimensional and three-dimensional representations, (4) Augmented Reality and (5) archive and dissemination of information.
