Abstract

Research at the Solutrean site at Fressignes (Indre) was largely preceded by digital input methods. Only the final campaigns (1998-2005) made it possible to deploy on the terrain an acquisition software for the spatial data and the archaeological characteristics, FrAcTool, which had been specially developed for the site. The data bank that had been elaborated reported the data on the terrain and completed it by using the other tools covering the analytical description of all the work that had been done since the research project had been started in 1983: digital retrieval of the coordinates, numbering of the photographs, stratigraphical layers, their spatial context and their georeferenced mosaicing. Moreover, all of the coordinates were checked simultaneously by mathematical models. The application of 3D is prepared by georeferencing and mosaicing of the images. The triangulation of the shadows of the objects gives the vertical sections of the terrain, the contours and the orthophotos. Laser surveys of the terrain constitute the final phase for the volumetric representation of the progressive spatial data during research.
