ABSTRACT:
Based on the results of a workshop in 2001, a research project for development of a geographical information system (GIS) for
cultural heritage has been started at the Techn. University of Munich in co-operation with municipalities and other regional
authorities in a rural and on agriculture and tourism depended region of the free state of Bavaria. In many institutions valuable data
of the history of the region and the culture landscape and of architectural monuments have been collected and stored. Overlaying and
combined information in GIS with considerable analysis and visualisation methods can supply an important contribution for the
sustainable development of the rural area. Thereby temporal survey and analysis of cultural data are playing a special role. As a result
of the combination of current and historical data valuable hints arise from the procedures in cultural history and can be used for
future planning. The paper describes aspects of object-oriented temporal data modelling and application in a large-scaled cultural
heritage geo information system.
ZUSAMMENFASSUNG:
Die Technische Universität München beschäftigt sich seit mehreren Jahren auf Initiative eines Workshops mit Gemeinden und
anderen behördlichen Verwaltungen mit der Entwicklung eines Geoinformationssystems (GIS) für kulturelles Erbe in einem von
Landwirtschaft und Tourismus geprägten, ländlich strukturierten Gebiet in Bayern. An vielen Stellen werden wertvolle Daten über
die Geschichte einer Region, über die historisch Kulturlandschaft und Baudenkmäler gesammelt und gespeichert. Die
Zusammenführung und gemeinsame Auswertung in einem GIS mit umfangreichen Analyse- und Visualisierungsmethoden kann
einen wichtigen Fachbeitrag zur nachhaltigen Entwicklung ländlicher Gebiete liefern. Eine besondere Bedeutung hat dabei die
zeitliche Erfassung und Auswertung der Daten. Durch die Kombination der aktuellen mit historischen Situationen ergeben sich
wertvolle Hinweise über die Veränderungsvorgänge in der kulturellen Geschichte und können in zukünftige Planungen eingebracht
werden. Das Manuskript beinhaltet Aspekte zur Modellierung objekt-orientierter temporaler Datenmodelle und deren Anwendung in
einem großmaßstäbigen Geoinformationssystem für kulturelles Erbe.
1. INTRODUCTION
For some years the Techn. University of Munich has been
working to develop a GIS for cultural heritage in co-operation
with municipalities and other regional authorities.
The area under investigation is the Achental, a structurally rural
region of the free state of Bavaria at the north edge of the Alps,
near the border to Austria, witch depends on agriculture and
tourism (Figure 1).
In many public and private institutions valuable data of the
history of the region, the culture landscape and of architectural
monuments have been collected and stored. Overlaying and
combining this information in GIS with wide analysis and
visualisation methods can supply an important contribution for
the sustainable development of the rural area.
Closely working together with the regional authorities for
preservation of monuments and historic buildings, with the
district office, with the district office for rural development,
municipalities and citizens there was made an analysis of
requirements to the possibilities of using a GIS for historical
questions about cultural heritage.
The paper introduces some results of the analysis of
requirements and some aspects of modelling a temporal GIS for
cultural heritage using UML (Unified Modelling Language).

In the following chapters a prototypic realisation of a temporal
GIS for cultural heritage is shown, in which the object oriented,
temporal data model has been implemented in an object
relational database (Oracle 8i) and therefor is combinable with
available data in a spatial database (ESRI).
A platform independent software application based on Oracle
Extensions to JDBC has been developed to query and visualise
the historically interesting spatial and attribute data. The access
from the application to the geo-referenced data and ESRI-
SDE is made by MapObjects (ESRI).
