The web application shows a 3D model of the city of Brno at the level of detail 2 (LOD2). As the application is based on two data sources, the buildings are displayed in different detail .

The application contains a more detailed and accurate model, which currently covers part of the city (approximately 17,000 buildings in the wider city centre) and which was created from aerial photographs taken in 2020 by using stereophotogrammetric method. This model was created by TopGis.

At the same time, you will find here a 3D model created by the Brno City Chief Architect’s Office (KAM), which contains buildings for the whole city, but is rather indicative - the height of buildings, roof type and its orientation may not correspond to reality.

Both datasets are available for download and free use. You can find the accurate 3D model here and the indicative 3D model here.

The scene also includes a 3D model of trees which is based on urban greenery data. The digital terrain model which serves as the base elevation for the web scene was developed by TopGis in 2019.

The application has been optimised for the current versions of Google Chrome and Mozilla Firefox (with WebGL support). It is recommended to run the application with a graphic card with a minimum memory of 2 GB and a high-quality internet connection. The web scene’s rendering speed depends on these parameters. If you do not see the building model in the scene, please try to open the application in another web browser.

The web application is based on the ESRI platform and its administrator is the Brno City Chief Architect’s Office (KAM).

The original application of a 3D model of the city of Brno in the level of detail 1 (LOD1) from 2017 is available here.
