Integration of Hybrid Outdoor and Indoor Surveying. A Case Study in Spanish Renaissance Style Towers

Abstract

The fusion of different image- and range-based techniques is acknowledged as the best option for threedimensional surveying of objects displaying a complicated geometry at different scales and/or resolutions. A special case deserving still several challenges involves to towers which represent a compendium of constructive elements and, consequently, a large amount of problems related to conservation or maintenance interventions. In this work, we display an extended photogrametric approach which includes elements information systems in Architecture with a special regard to structural analysis and some aspects of materials analysis. We illustrate our approach with several examples regarding a hybrid surveying of architectural Renaissance towers which have been constructed in several agrarian zones of the kingdom of Castilla (Spain) along 16th and 17th centuries.

Terrestrial and Aerial Ground-Penetrating Radar in Use for the Architectural Researches: Ancient 16th Century Water Supply and Drainage at the Monastery of El Escorial (Madrid, Spain)

“…Precedent researches on the use of aerial oblique visual and infrared images for archaeological researches are numerous: among the recent contributions can be mentioned: about low cost aerial photographic techniques, see Eppich, Almagro, Santana and Almagro (2011); about producing georeferenced cartography from single oblique Photos, see Bozzini, Conedera and Krebs (2011); about the identification of archaeological remains from the air, see Aber, Marzolff and Ries (2010), as well as Mirijovsky, Martinek and Brus (2011). The use of small remote-controlled helicopters for architectural and archaeological surveyings is being applied for long by the DAVAP Research Team at the University of Valladolid (Sánchez, San José, Fernández, Martínez and Finat 2011). Similarly some interesting experiences have been accomplished using GPR, as those led in the Alhambra (Granada, Spain) by Rafael Gómez (2008), and by the team of Prof. Conyers at the University of Denver (Conyers, Ernenwein & Bedal 2002), who uses the GPR mapping for the detection and interpretation of cultural materials.…”
