An information system for medieval archaeology based on photogrammetry and archaeological database: the Shawbak castle project

The paper presents an interdisciplinary project which is a work in progress towards a 3D Geographical Information System (GIS) dedicated to Cultural Heritage with a specific focus application on the Castle of Shawbak, one of the best preserved rural medieval settlements in the entire Middle East). The Shawbak archaeological project is a specific and integrated project between medieval archaeological research and computer vision done thanks to a long cooperation between University of Florence and CNRS, LSIS, Marseille. Focusing mainly on stratigraphical analysis of upstanding structures we provide archaeologists with two-step pipeline. First a survey process using photogrammetry, both in a traditional way with additional annotations and using the most advanced technique to obtain dense maps and then a tool for statistical analysis. Two main applications are presented here, stratigraphy analysis with Harris matrix computed on the fly from the 3D viewer and statistical tools, clustering operation on ashlar in order to show new relationships between the measured artifacts. All these developments are written in Java within Arpenteur framework[4].

The Evolution of Masonry Technique in Islamic Military Architecture: the Evidence from Shayzar

Abstract This article describes and discusses the building sequence identified with the stratigraphic analysis of an architectural complex at the site of Shayzar in Syria. This sequence appears to represent the general sequence of occupation for the castle of Shayzar. It also provides evidence to illustrate the evolution of masonry technique at the site over many centuries; a number of dated inscriptions preserved at the site has contributed absolute dating to a significant part of this sequence. This evidence was recorded in the course of the first season of field work carried out in the spring 2002 for a project of archaeological investigations, the Progetto Shayzar.
