Abstract

The purpose of the present paper is to highlight the advantages deriving from a multidisciplinary approach to the surveying and rendering of historic-architectural legacy. Surveys are performed to detect, study and record typical and irregular features of a building, as well as to show its structural morphology and static conditions; they involve, as such, measurements as well as readings of metric data, aimed to master the architectural complexity andevery other aspect of the survey object – metric, morphological and tectonic – in order to achieve the broadest possible related knowledge. New surveying techniques, such as 3-D laser scanning and digital photogrammetry, offer effective tools to meet specific analysis requirements, although in some cases they may be partially inadequate: in fact, for their full exploitation, both these techniques require the area in front of the surveyed object to be free from obstacles. Since this cannot always be achieved, it can be useful to provide for an integration of collected data with direct measurements. The survey described in this paper, performed on the Stampace rampart in Pisa, has been studied, designed and carried on so that computer-based surveying and rendering techniques and methods would be usefully complemented by traditional ones. In detail, only partial accessibility to every section of the architectural compound has called in turn to the joined implementation of innovative surveying techniques – terrestrial laser scanning – and traditional ones, the latter integrating the former. For this purpose, a topographical framing network has been set up so to allow merging of data collected by different techniques in a single geo-referred system, by joining vertices conveniently placed all above the area. The drafting of the graphical survey documentations has been focused not only on the rendering of geometrical and dimensional features, but also on the synthetic presentation of matter, structural and historical data analytically collected alongside the strictly surveying job.
