The variability of data collecting methods was high in this case. This would be problematic for small companies working in this area 
and interesting in this kind of work. It would almost be necessary to combine surveying methods on one side and photogrammetric 
methods on other side. This brings requirements of appropriate equipment, software and experienced operators. The co-operation of 
companies looks as a good way to accomplish this task. 
During the process of joining all of these models together, some problems with the data relationships and data homogeneity ap 
peared. This required checking the data directly with the physical building of the theatre. The amount of these problems was not so 
large (some details) because of monitoring of this during processing.

There will be three-dimensional photo-realistic model of the entire theatre. What would be the next step? The trend leading to 
creation of Spatial Information Systems is obvious. In this particular case it will be something like Cultural Heritage Information 
System. The second way, which has a very close relationship to the first, is the presentation of three-dimensional data via Internet - 
virtual tours, virtual tourism. That is why it is necessary to continue with new technologies leading the way to utilising three- 
dimensional data and their actualisation.
