the hypothesis of a former temple located at the top of the
hillock Kuyiikkale (see also Figure 9) one can calculate the
maximum height of the former theatre platform if one assumes
that the platform should not be an obstacle for the theatre
visitors. The result of this calculation is, that the visitors had the
temple in their view field while joining a theatrical performance
if the platform was not higher than 9 metres.

Figure 9 shows the complete landscape area which could be
overlooked by the theatre visitors.

Visibility analysis can be used for many other purposes, like for
the detection of suspected watchtower locations which were
needed to control a certain area, for an analysis to answer
questions like ‘from which points of the ancient trade roads was
it possible to see the city?’, ‘from where could a certain
religious building be seen?’ or, in turn, ‘where is the most
probable location of a religious building which is assumed to be
seen from a certain area?’.
4.4.3 Other DEM applications: The slope as an important
terrain measure is strongly linked with many archaeological
research items, like landuse considerations, for instance,
because agriculture or building construction may be restricted
to a maximum terrain slope. Natural erosion processes strongly
correlate with slope measures, artificial slopes may have been
created to improve the defence capabilities against attackers,
steepest path calculations can help to discover remains of
irrigation systems. All slope calculations needed in such cases
can be performed very easily once a DEM is available.
Automatic cross section calculations can be used for the
validation of suspected courses of paths, roads, rivers, etc.
Visualisation is another wide DEM application field which will
be discussed shortly in the context of the Internet presentation
of the Tavium Research Project (see next section).
5. TAVIUM RESEARCH PROJECT WEBSITE
Meanwhile, the Internet became a standard medium for
information exchange. The advantages of this new medium are
obvious: information can be accessed all around the clock from
everywhere in the world, the contents of websites can be
updated easily within a very short time span, all information is
provided at a relatively low cost level as compared to classical
print media, but still at a considerable size, etc. In some way a
certain standard of how to structure and to present information
on the Internet is already available. A website for the Tavium
Research Project was created which meets the requirements of
all the de facto agreements with regard to the arrangement of
information on the screen, to the navigation through all pages,
to the use of commonly used icons and other components of a
widely accepted Internet look and feel.
5.1 Website Design
A flat hierarchy of categories was established to facilitate the
navigation on the website (see Table 3). At the moment of
publication the website contains more than 150 Internet pages.
Actually, the pages are only available in German language, but
the intention is to provide the presentation in English language,
too, and, possibly, even in Turkish language. Figure 10 shows
the front page of the Internet presentation.
