Dal rilevamento integrato al SiArch-3D: il caso di studio della chiesa di S. Paolo a Peltuinum (AQ)

From integrated surveying to SiArch-3D: the case-study of S. Paolo church in Peltuinum (AQ). The church of S. Paolo near Peltuinum (AQ) has been chosen as case study to test the SiArch, i.e. the Architectonical Informative System studied by the Research Unit of L'Aquila University. Before the earthquake of ApriI 6th 2009, happened during the research period, the building was surveyed using digital photogrammetry techniques by PhotoModeler Scanner 6 software. After the seismic event the church was surveyed with laser scanner. About architectonical surveying, according to the used instruments, digital photogrammetry techniques are simpler, faster and more economie, but surfaces built by photogrammetric point clouds are satisfying only for flat façades or with regular curvature, and elements with limited prominence. Using all surveying data, was reelised the church's 3D photorealistic model. To build an Architectonical Informative System, the first step is planning the database, that required to compose 3D model according to constructive elements. Then the 3D model, textured by Autodesk 3DStudioMax 20 1Oand exported in *.3ds format, is imported in ArcScene of ESRI ArcView 9.3 software. This procedure gives the possibility to realize an architectonical informative system with photorealistic 3D model into GIS environment. Moreover another testing is about the importation of churciis mesh textured surface, realized by digitaI photogrammetry techniques, into ESRI GIS environment.
