The graphic survey of the architectural heritage supported by the 3D laser scanner. Case study: the Castellot house

Abstract

[EN] The architectural graphic expression, with all the variants that make it up, strengthens a substantial part of the process of approaching the project, also of its resolution. When the architectural intervention corresponds to the rehabilitation of a historic building, the aforementioned link acquires greater prominence, both in the previous phases of analysis, and in the consequent decisions that will derive from them. The help of technologies in the capture of information and the possibilities of virtualization provided by computer applications, have determined both the work methodologies and the forms of graphic representation to obtain results. This article describes the processes carried out for the graphic representation of a Renaissance palace in the province of Teruel, Casa Castellote, as a starting point to advance in its knowledge. Every graphic survey, any virtual model analyzing an architectural object, the intangible contribution of the initial sketches, and the conclusive planimetric representation configure an essential scientific research to address a project solution. This analytical graphic process, as well as the consequent creative graphic process, require systematization. The result is the obtaining of a digital model that will allow the study and analysis of the model through different visualizations, whether planimetry, or virtual three-dimensional models, which, in addition, enable accessibility to the documentation of the heritage asset and its dissemination to society.
