Bundesstadt Bonn

Online city map is available again

The online city map of the City of Bonn at as well as the map services of the Geodata Infrastructure (GDI) Bonn and the spatial services of the Open Data portal are available again to the usual extent - except for the current traffic situation.

Against the backdrop of the general IT threat situation, which has worsened significantly and is assessed systematically as well as regularly, the city administration had proactively taken the City Plan temporarily offline on January 13, 2023. This measure served to maintain an optimal level of security. 

The Bonn online city map at (opens in a new tab) has been a reliable source of information for citizens, business and science for more than 10 years.

In coordination with central IT and the Chief Digital Officer of the City of Bonn, the Office for Land Management and Geoinformation is designing a modern Urban Data Management (UDM), which includes a data platform as well as the topic of data strategy. This is an important step in the digital transformation of the administration and the city.

In Urban Data Management, the previous geoportals, and thus also the online city map, will be completely merged. Due to the complexity of the topic and the scope of the existing geodata infrastructure, the project will be successfully implemented under optimal conditions by the end of 2026.
