The objective of the study is to visualize the Vltava River valley in the area of Kamýk nad Vltavou. The workflow involves the georeferencing and vectorization of map data in ArcMap. Based on this processing, 3D objects are procedurally modelled in the CityEngine programme. The resulting 3D objects are complemented with a photogrammetrically created model of the Kamýk Reservoir. The results are presented in the form of map applications. This study aims to present the workflows already used in the project and the procedures planned for use during further processing. Many of these techniques are already well-known and well-established, such as raster data georeferencing, raster data vectorization, drone-based photogrammetry, manual and procedural 3D modelling or statistical, socioeconomic and hydrological studies of changes over time. However, what makes this project different is the combination of all these procedures within one project of the processing of the entire Vltava River valley territory. The main objective of the study is to create 3D models in the CityEngine programme depicting the state of the Kamýk nad Vltavou cadastral area in different periods of time (before, during and after the Kamýk Dam construction). The obtained and processed data used in the creation of these models will subsequently also be employed within the Vltava Project for the investigation of the impact of the Kamýk Dam construction, the Vltava Cascade as a whole and other external impacts on the entire Vltava River valley.
