seen from a spatial information specialists’ point of view. Results of work in several working areas will be presented: establishment 
of a spatial reference system, fusion of spatial data obtained from different sources with special credit given to the role of digital 
between all project participants and other interested persons. Readers will get an idea how to combine data from various sources 
project information system. 
ZUSAMMENFASSUNG: 
Seit 1997 finden im Bereich Yozgat, einer Stadt in Zentralanatolien, an deren Stelle sich Tavium, die ehemalige Hauptstadt des 
Hettitherreichs befand, archäologische Forschungen statt. Der Artikel befasst sich mit den Vorbereitungsarbeiten für zukünftige 
Ausgrabungen im ehemaligen Stadtbereich, und zwar aus der Sicht der raumbezogenen Informationsverarbeitung. Ergebnisse aus 
verschiedenen Arbeitsbereichen werden vorgestellt, und zwar die Einrichtung eines räumlichen Bezugssystems, die Vereinigung von 
raumbezogenen Daten aus verschiedenen Quellen, wobei die Rolle von digitalen Geländemodellen besonders berücksichtigt wird, 
und, schlussendlich, der Entwurf und die Realisierung einer Internet-Präsentation, um den Informationsaustausch zwischen den 
Projektbeteiligten und anderen interessierten Personen zu unterstützen und zu fördern. Der Leser erhält eine Vorstellung, wie sich 
Daten aus unterschiedlichen Quellen mit verschiedenen räumlichen Eigenschaften in demselben räumlichen Informationssystem 
verknüpfen und die daraus gewonnenen Informationen in einem webbasierten Informationssystem integrieren lassen.

ABSTRACT: 
Since 1997 archaeological research has taken place in the area of Yozgat, a central Anatolian city where Tavium, the ancient capital 
of the Hittite Empire was located. The article deals with the preparatory work for future excavations in the area of the ancient city 
terrain models and, finally, design and implementation of an Internet presentation to support and promote information exchange 
with divergent spatial properties in one spatial information system and how to integrate this information in a web-based overall

Minor. Nowadays, we find there only the remains of ruins, 
notably of a theatre, which survived the use of historical 
material in building the neighbouring village of Yozgat. Figure

around 200 kilometres east of Ankara, the capital of modern 
capital of the Galatian tribe of Trocmi, and at the same time, 
relations with the neighbouring countries were recorded in a 
large number of tablets, which recently were nominated and 
recommended for inclusion in the UNESCO Memory of the 
World Register (UNESCO, 2001). Tavium, or Tavia, was the
