Among 3D tools, photogrammetry has received growing attention for the modeling of under¬ground spaces. The flexibility of its implementation and the wide field that it can cover encourage its use for recording decorated walls and their contexts. As part of a developing program ANR microanalysis on prehistoric art, 3D photogrammetry modeling were carried out in caves in Blanchard (Indre, France) and Rouffignac (Dordogne, France). I make quickly reference at two examples which are developed in article: 1) the numbering and analysis of the condition of the walls and the engravings; 2) localization in 3D pointcloud of archaeological data (paintings, prints, objects of flint or bone stuck into the wall) and links with different kinds of information about them (type, descriptions, dimensions, drawing, etc.). These applications illustrate the possibilities offered by current 3D tools in the study of rock art, and are sometimes new ways for the study of prehistoric representations in their geomorphological and archaeological context

Up to now Geographic Information Systems have rarely been used to study decorated caves. The research conducted for more than 12 years now in the Chauvet cave required a unifying tool that would collect, on the same support, all of the different types of information gathered from the various fields of research involved in the study of the cave. The objective was to find a system that could centralize and cross reference all of the information acquired. Besides just a filing system, this tool was also needed to promote the development of new research for a better comprehension of the cave and the way in which it was occupied. The diversity of the data to be integrated and the needs of the different disciplines required a co-constructive approach to the support and to the means for representing the data. In order to be able to cross-reference both the data collected from the soil and from the walls we decided to direct the GIS developments towards the integration of three dimensional information. The first GIS applied to caves with paintings should also be a useful reference tool for the study of other caves in the future. This article is intended to describe the different stages we passed through for the implementation of this tool, by analyzing the limitations, the choices made and the prospects we envisage.
