An improved stratigraphy based on laserscan survey

Pubblicazione degli atti del convegno su CD-Rom. Purpose: This is a presentation of same case studies conducted by our survey lab on some archaeological monuments. The main objective is to underline the use of laserscan pointclouds for viewing and managing stratigraphy in a point based 3D Model. Methodology/Approach: The main subject of the presentation will be the digital surveys of the Baptistery in Lucca and some area from Villa Adriana in Tivoli. Starting from the digital survey based on 3d laser scanning of those monuments (conducted using Leica HDS systems) we will show our procedure to manage and archive the data of those surveys together with some evolved strategies for transferring traditional two-dimensional solutions for reading and drawing into the three-dimensional datascape. All the survey presented come from our latest experience in laserscan survey, while our laboratory has work, during the last two years, on almost forty survey of monumental architecture, some of them with main archaeological features. Finally: some considerations about how innovative could be the three-dimensional stratigraphy solution for a better understanding, documentation and diffusion of excavation results while working on the site as when the site is open for tourist frequentation. Results: The production of well suited product of digital survey with an appropriate language towards archaeology, based on the understanding of the monument characteristics instead of mass-gathering information and unshaped documentation. The development of easy to use procedure for stratigraphy building in 3d data models, with a workflow system suitable for technical operators as well for naïve users.
