Photogrammétrie appliquée à l'étude architecturale et archéologique, exemples de quelques chantiers récents

Abstract

International audience ; The application of photogrammetry in archaeology has developed greatly in the last ten years. A short while ago, the technique was confined to prestigious operations because it required sophisticated and expensive technical means. Nowadays, it can be used by all operators thanks to the increase in computer hardware and the development of specific software, such as those based on the close-range photogrammetric technique. The democratization in the use of these powerful, fast and accurate tools allows users to increase the number of surveys and opens, at the same time, new research perspectives. In addition, the ability to manage more data in a short time makes it possible to deal with new topics that were previously difficult to face, while their efficiency changes the standpoint and the interest on the subject. Nevertheless, such changes involve developing new intervention strategies and working methods. Photogrammetric processes have been implemented on three recent archeological programs in Egypt: the Tiberius Gate at Medamoud, the el-Nabih cistern in Alexandria, the Ayn-Soukhna charred boat. The efficiency and the interest of photogrammetric solutions have been tested on these various fieldwork contexts.
