Abstract

In our solution a rich database model is used to represent stratigraphic data. This allows for the easy selection of ranges and types of data for visualisation. Using a simple data management application, several archaeologists can easily share the same dataset, enabling group work. Using a database management system for data storage instantly gives numerous benefits, which, among others, include efficient data representation, robust data access, transactional processing and data integrity constraints (verification of possible values, their constraints, their relationships, etc.). A prototype of an X-VR based Harris Matrix visualisation system has been developed. 3D diagrams can be displayed using standard VRML plug-ins to internet browsers without installing any specific software. The system has been tested on data from Gdańsk town excavations – Szafarnia (Schaferei) site.
