The integrated digital approach to the survey and the geometric modeling of the Archaeological buildings. The case study of the amphithe atre into pompeii’s archeological site

The paper summarises the integrated digital survey activities of the Pompeii Amphitheater conducted through the integration of four digital technologies: 3D laser scanning, GPS and traditional topographic surveyings, high-resolution photographic mapping and digital photogrammetry techniques. The georeferenced point cloud model has been analysed to study the geometric shape of the building and necessary 2D representations are presented, extracted from 3D model.
