2. PROJECTS 
In the Czech Republic, there are lots of monuments of various architectonic styles. At the Laboratory of Photogrammetry and Lab. of 
Quantitative Methods, usually 4-6 precise projects per year are carried out. Recently, a method of simple digital photogrammetry for 
filling of the monument database with help of students has been implemented. 
Based on a grant of the Czech Grant Agency, a large long-term project for historical monument documentation by using a new 
digital technology has been started (1999-2003). The project is defined as a complex research for historical monument documentation 
using digital photogrammetry, physical methods and GIS. For testing a new technology, the historical centre of the town Tele, (which 
is included into the list of the world monuments of UNESCO) is selected. 
The targets of the project are to do the 2D and 3D measurements of the historical centre of the town Tele together with testing of new 
digital methods for the terrestrial photogrammetry. Another aim is to propose an optimum procedure for measuring historical objects 
and especially creating of the classified knowledge about Tele gained through historical and architectural analysis in the form of an 
information system connected to the state coordinate system.

3. CONCEPTION AND METHODOLOGY 
The measurement of the historical part of the town Tele represents the spatial (3D) evaluation of about 50 objects (facades) and 
several interiors of historical buildings (the vaults in churches). The project aim is not only documentation, but also the result 
presentation using new technologies. For the photogrammetric measurements, various methods will be used. For the 
photogrammetrical method, good visible control points defined in 3D coordinates of the state coordinate system are needed. The 
number of control points differs with the method; usually it is necessary to determine 6-10 control points for each object. For the 
connection to the neighbouring object some further connecting points will be used. Due to number and the complexity of the objects 
approximately 1000 control and connecting points must be measured and connected with the state coordinate system. A special 
geodetic micro-network was stabilised and measured by the surveying company in Jihlava. There are several methods for the 
determining of such a number of control points:
