ABSTRACT
The variety of the cartographic 3D-visualisation is constantly increasing and thereby more and more fields of
application are being developed. These facts require that the coherence of technical, perceptive-psychological
and cartographic-theoretical aspects has to be subdivided and classified. Through these formulations of
interdependence of the single parameters shall be pointed out. The consideration of communication-theoretical
and perceptive-theoretical aspects shall lead to a purpose-oriented realisation of the 3D-visualisation techniques
according to the user’s necessities.
KURZFASSUNG
Das thematische Gebiet “Kartographische 3D-Visualisierung”, dessen Vielfältigkeit ständig zunimmt und dem
immer mehr Anwendungsbereiche erschlossen werden, erfordert, daß die Zusammenhänge von technisch-
verfahrensspezifischen, ^ wahrnehmungspsychologischen ^ und kartographisch-theoretischen — Faktoren
aufgeschlüsselt und klassifiziert werden. Hierdurch sollen Ansátze einer Interdependanz der einzelnen Parameter
aufgezeigt werden. Die Berücksichtigung kommunikationstheoretischer und wahrnehmungstheoretischer
Aspekte soll zu einer anwendergerechten und verwendungszweckorientierten Umsetzung der 3D-
Visualisierungstechniken führen.
1 INTRODUCTION
1.1 Scientific Application Fields of 3D-Display Techniques
For GIS and remote sensing environments, common as well as new innovative techniques are applied to 3D data
sets, virtual reality or volumetric models.
The advantages of 3D representations assumed in the higher validity of the special visualisation form are also
more and more used in different kinds of atlases (for example the Swiss National Atlas) as in large-scale (virtual)
representation forms.
1.2. Activities in Theory of Cartography
At the Institute for Cartography of the Dresden University of Technology research is, i.a., especially focussed on
the development and application of theory of cartography. This research field is strengthened by the role of the
Institute as one of the international centres of cartographic semiotics also within the scope of ICA (Koch cum.
lit. 1999/2000; Wolodtschenko cum. 1it.1999).
1.3 Consideration of Theoretical and Cognitive Aspects
In cartographic sciences the cognitive aspects especially have never been so popular like the perception-
psychological ones. This is mainly due to the complex data material which is comparatively difficult to interpret.
