AFT is an expert land survey and topography office situated in the urban area of Rouen (Haute-Normandie). For about six years, its land surveyor and photogrammetric activities have allowed it to work on archaeological sites. A new department, named AFT Archaeology, is now in charge of taking topographical surveys in order to produce 3D models of the archaeological sites and historical monu¬ments. First, in this article we are going to describe the laser scan techniques, the kind of laser used and the information processing. Then, we are going to illustrate some applications on archaeological and historical sites and also some exceptional objects we scanned. These examples of what we are doing will be illustrated by a 3D model presentation, section and map. In a few words, this little introduction will aim to show the interest of laser digitisation and 3D modelling techniques: perfect digital copy, extremely accurate and exhaustive (up to 1/10e mm of precision), study support, evaluation support (3D presentation in museography, pictures for archaeological excavation reports, etc).
