Drone-based data collection is suitable for capturing temporary and shot term changes (e.g. events or construction sites) or structural changes within the city and updating the city-wide data of the Digital Twin Munich.
Spatial data, especially realistic 2D and 3D data, provides the most important basis for the Digital Twin Munich. This data is collected through regular aerial surveys of the entire city every two years. However, many of the city's administration duties require more up-to-date data. This is where drone-based data collection is particularly useful. Medium-size areas or individual objects can be captured rapidly by drones with very high spatial and real-time resolution and then integrated into the Digital Twin Munich. One example is the annual Oktoberfest in Munich. The final setup is completed just before the event opens. In this case, drone-supported data collection is particularly suitable for the photogrammetric capture of the event site in the quickest time possible. The resulting 2D and 3D maps support the work of the relevant departments before and during the festival week.
