This presentation introduce two applications of digital photogrammetry in an archaeological context: the first one focuses on data survey and management and the second one deals with complex surface definition and laser scanning. These two applications are made with the web based photogrammetric software, ARPENTEUR system, (Architectural PhotogrammEtry Network Tool for EdUcation and Research) available at http://www.arpenteur.net. ARPENTEUR is a set of tools developed in MAP laboratory dedicated to archaeological survey and also used to teach photogrammetry

After a brief presentation of the ARPENTEUR project we will focus on a project in medieval archaeology in collaboration with the “Dipartimento di Studi storici e Geografici” of the University of Florence (Italy) who are responsible for the archaeological research. The case study is the Castle of Shawbak, traditionally known in historical reports as the “Crac de Montréal” in Jordan.

The second application combines the laser scanning techniques and close range photogrammetry. One of the main objectives of architectural and patrimonial survey is to provide a precise documentation of the status quo of the surveyed objects (monuments, buildings, archaeological object and sites) for preservation and protection, for scientific studies and restoration purposes, for the presentation to the general public. Complex object, not planar or with ornaments and decorations require high-density and high-resolution spatial data.

The laser scanning techniques and close range photogrammetry can offer two complementary sets of instruments and technologies able to answer the specific requirements of architectural and archaeological surveys. The second case study is about the ancient water supply system of Petra, Jordan. Given the inaccessible nature of the site, a hybrid survey method was relevant. This case study is a part of a project in collaboration with Istituto di Geodinamica e Sedimentologia e Centro Studi Archeologici “CE.S.AR”, Università degli Studi di Urbino, Italy and ITABC laboratory, (Istituto per le Tecnologie Applicate ai Beni Culturali), Consiglio Nazionale delle Ricerche, Rome, Italy).
