Title
New perspectives to save cultural heritage

main contribution is in the field of training and education,
where simple tools and teaching material can be used without
additional costs, and where a knowledge multiplication can be
assumed.
2.2 Digital Presentations
Setup of Surveying Instruments: This presentation shows the
step by step setting up of a geodetic instrument horizontally and
precisely over a ground point. Short movie sequences help to
visualize manual procedures, that are difficult to explain in
words (Fig. 2).
The teaching material should become widely available in the
near future. The material has been compiled with Microsoft®
PowerPoint and converted to hypertext documents, which can
be made available on the Internet. All the data is available in
widely distributed formats, such as JPG and GIF for images and
MPEG for movie clips. All vector graphics have been
transformed to raster images due to the lack of a standard vector
data format.
Traverse: This presentation shows the principle of a traverse,
how it has to be computed and why this concept is
recommended for different applications. The different types of
traverses are compared. This topic is usual difficult to explain to
people without a geodetic background. The fact that the
graphics and the calculations are shown side by side on one
screen help people with a visual oriented perception to
comprehend the concept, theory and praxis.
Texts are short and are available both in English and in German
at this time, but could easily be translated into other languages.
We will do this on demand if a qualified person commits to do
the translations. In the future it is planned that the number of
presentations available will be increased. However, at present
there are the following five presentations:
Basic Surveying Equipment: Basic Geodetic Equipment is
explained, especially theodolites, total stations and accessories.

Design of a Geodetic Control Point Network: This
presentation shows a hierarchical approach to control point
network design for the indoor and outdoor survey of a site
containing two buildings. The net is consolidated step by step
by traverses and polar measurements. The concepts of increased
reliability and accuracy are explained during the network design
process.

Stereo Photogrammetry: This presentation shows the
principles of a stereo photogammetric survey. The concept and
the data acquisition is explained, also the connection to human
vision. An example highlights the steps of image orientation
