3d Recording and Modelling of Mining Heritage: The Monserrat Mine, Sierra Minera of Cartagena-La Unión, Southeast of Spain

Abstract

ABSTRACT:Mining heritage is essential to understand the history, landscape and cultural manifestations linked to mining industry. The Mountain Range of Cartagena-La Unión is one of the most relevant old Mediterranean mining areas, with mining sites that were already exploited before the Carthaginian domination. It was declared a Site of Cultural Interest in 2009. Our aim is to document and to enhance its premises, which are currently in a bad state of preservation and have been plundered. The methodology that we suggest combines various techniques, such as laser scanning, LIDAR and digital photogrammetry, in order to obtain the best results based on the characteristics of the objects to be inventoried. For this study, we have chosen an area in which a digital model has been created by means of terrestrial laser scanning and airborne LIDAR, then we have textured it with the images taken. With this model, it is possible to measure the deterioration and displacement suffered by its elements, in particular, the chimney and the boiler room.

Condition Assessment of Heritage Buildings via Photogrammetry: A Scoping Review from the Perspective of Decision Makers

“…Another investigated aspect concerns the verification of the verticality of slender elements like masonry towers or chimneys by taking direct measurements of vertical displacements on 3D data, by comparing different height transversal sections, or with the help of best-fitting algorithms. By way of example, García-León et al (2017) used reality-capture 3D data of a masonry chimney in an old mining heritage in Mountain Range of Cartagena-La Unión (Spain) [89]. The workflow entailed the combination of LIDAR and photogrammetry to obtain an accurate photorealistic representation of the chimney, in which both visual assessment of crack patterns and direct measurements of the cross-section-centres' displacement at different heights supported technicians in understanding the risk of collapse of the structure [89].…”

In the same direction, the work of Markiewicz et al (2017) focused on the verticality control of a monumental masonry tower within a medieval fortification (Kraków Bishops' Castle in Ił ża, Poland).…”
