ABSTRACT: Chateaux and castles are an important part of cultural heritage in the Czech Republic. The aim of this project is to develop a public web mapping application capturing the changes of manors and surrounding landscape during the last two centuries. This mapping application will be based on digitized and georeferenced old maps and various plans as well as both historical and up to date photographs. The application will allow users to compare various rasters, vector layers and photos from different time periods. Two-dimensional web mapping application will be also supplemented with a 3D web scene based on procedural modelling rules. The procedural modelling approach provides a quick way to create 3D models of buildings within a manor from 2D vector layers. Rules can be then continuously refined or even high detailed non-procedural models can be added to depict the most significant buildings (i.e. chateaux, castles or churches).
