Examples of different details visualized in 3D
LOD2 ~ Automated visualization of LOD2 buildings constructed using combination of digital terrain model, digital surface model and buildings footprints. Automatic detection of roof type and height were used. Roof shapes are generated using City Engine Procedural rule.
Data sources: DTM 5G and DSM 1G – sample data.

LOD3 ~ Kozel Chateau – visualization of chateau area in a level of detail corresponding to CityGML LOD3: portraying detailed terrain, land use, buildings with windows, doors and facade relief, forests and freestanding trees, bushes, etc. Buildings models were created by 3D editing tools in SketchUp and converted to Geodatabase using CityGML SketchUp plugin and ArcGIS Data Interoperability Extension.
Data sources: surveying and CAD models of chateau Kozel.
Data sources: surveying and CAD models of chateau Kozel.
LOD4 ~ Chateau Chapel visualized in LOD4 (all details in both exterior and interior). Riding hall visualized in LOD3 for comparison. Buildings were created and converted from SketchUp using the same process as for LOD3 buildings.
Data sources: CAD models of chateau Kozel.

3D GIS for indoor navigation
IndoorGML ~ Visualization of four different navigational graphs in the building of Faculty of Applied Sciences, for: general public, wheelchair, evacuation, wheelchair evacuation. These graphs can be displayed simultaneously or dynamically switched. Each graph is originally created in IndoorGML format and is ready to be used for navigational purposes.
Data sources: CAD models by Ateliér Soukup.

Visualization of 3D analysis
Visibility analysis ~ Visualization of driver’s visibility conditions 3D analysis. Red point shows a car entering a junction. Green areas shows the driver’s view.
Source data: DTM 5G, Ortophoto of the Czech Republic, Laser scan surveying.

Cesium based 3D solutions for HS Layers NG
Rostěnice farm application visualises geographical data in a 3D environment. This can help a farmer to better understand the farm fields. The farmer can explore the relation of the yield potential to the topography, slope, orientation and topography wetness index in his/her field. The farmer can check the parts of fields with steep slopes and how the machinery deals with them (checking the machinery tracklogs). The technical details can be found here. The application uses the digital terrain model of fifth generation and the digital surface model of first generation produced by ČÚZK.

This application visualises the Open Land Use dataset on top of the EU-DEM terrain model in a perspective view. Displaying the data in 3D environment helps the user to explore an area of interest in more natural way than a traditional map. Moreover, the user can add a web map service of his choice (as long as the WMS is in WGS84 coordinate system) to make custom 3D mash-ups. The technical details can be found here.
Noise modelling
Noise pollution emitted by traffic may vary significantly with difference in height and time. Unfortunately these differences are likely to stay unnoticed for 2D map user. As shown in our visualizations third dimension can be used to show user what might otherwise stay hidden or unclear.
