they are able to be modelled accurately and in greater detail using standard CAD software (Jedlicka et al. 2013). On the other hand, it is not possible to model all buildings in the surroundings this way. It would be highly time consuming and, of course, there is no existing historical documentation of all objects inside the manor. Many buildings do not exist anymore or they were significantly rebuilt or renovated. Some information can be acquired on the basis of old photographs, but mostly the only data source available is the old map. Therefore, surrounding buildings can be reproduced based on vectorized old maps using procedural modelling approach. Polygon layers with footprints are used as a foundation for buildings. Missing information (e. g. the height of buildings) can be chosen randomly or better considering the look of buildings in a given time. ESRI City Engine is used for procedural modelling. One example of the procedural modelling result is displayed in figure 7. Figure 7. 3D web mapping application - example of one scene of the chateau Mnichovo Hradiste Conclusion This article introduces a project focused on web presentation of chateaux and manors in the Czech Republic. Various sources of maps, plans and photographs are included and the most important map layers are described. Old maps and plans are georeferenced and close chateau surroundings on selected maps are vectorized allowing land-use comparison. Objects of economic and cultural background of domains are vectorized and later displayed as points of interest in the web mapping application. The application provides quick access to a specific chateau or castle using spatial bookmarks and shortlists as filters. It shows georeferenced old maps and various plans, vectorized objects and areas, as well as historical and up to date photographs. The application allows users to compare various layers and photos from different periods of time. Besides the classic way of presenting 2D data via web mapping application, this article briefly introduces the possibilities of 3D procedural modeling and presentation of 3D scenes on the internet. The 2D web mapping application can be accessed at http://gis.fsv.cvut.cz/castles. In the future, the application will be complemented by text information about chateaux, their surroundings, gardens, economic background of domains and their former owners, aristocratic families.
