SPATIAL INFORMATION SYSTEM OF HISTORICAL SITE – PROPOSAL AND REALISATION OF FUNCTIONAL PROTOTYPE

The development of the methods of spatial data acquisition together with progress in information technologies brings up a question about creation and usage of spatial models and spatial information systems of historical sites and buildings. This paper presents the current state of the “Live Theatre ” project. The theme of the project is the proposal and realisation of a spatial information system of the baroque theatre of Cesky Krumlov castle (UNESCO site). The project is divided into three main stages – creation of a 3D model, proposal of a conception of a spatial information system and realisation of a functional prototype. Spatial data were acquired by means of photogrammetric and surveying methods. An accurate 3D model was built in CAD system MicroStation and it is a photo-realistic (textured) model. The proposal of a conception of a spatial information system was the main result of the author’s dissertation. The essential feature of the proposed conception is creation of subsystems targeted on three spheres – management, research and presentation of the site. Functionality of each subsystem is connected with its related sphere; however, they are using the same database. Realisation of a functional prototype (with sample data) is a present stage of the project. During this stage we are solving several basic technological topics. Now we are concerned with spatial data, its formats, format conversions (e.g. DGN ⇒ VRML) and its connection to other types of data. After that we will be seeking a convenient technical solution based on network technologies (Internet) and an appropriate layout of data (database). The project is carried out in close co-operation with the administration of Cesky Krumlov castle and some other partners (e.g. Computer Graphic Group, CTU in Prague). This stage of the project will finish in the middle of next year (6/2005)
