From underwater photogrammetry to a web integrated documentation system: The case of the ‘grand ribaud f' estruscan wreck

The interdisciplinary work we present here is aimed principally at administering diverse types of information collected during an <br />archaeological excavation using a single data management system. The approach is global, from the consultation of three- <br />dimensional data to simple textual data to the addition of data captured by a digital photogrammetry system called l'Arpenteur <br />[Surveyor], which is fully integrated to the data management system. <br />We are using an object formalisation of the manipulated archaeological data using JAVA 1.3, the language chosen for all <br />developments, from the digital photogrammetry tool to the three-dimensional model generator (VRML or JAVA 3D) used as a <br />navigation interface in the database. <br />Following a brief introduction to the archaeological context, and the special aspects of the excavation due to the great depth of the <br />shipwreck, we will then present the existing system and explain the problems encountered. Not all of them have yet been resolved, <br />such as the translation of objects to and from the relational DBMS, the revision of data coming from different sources, and the <br />automatic generation of three-dimensional models as a navigation interface
