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
