IT security and data protection are the top priorities for the Bonn city administration. To ensure an optimum level of protection, it was therefore necessary at short notice to take the stadtplan.bonn.de portal and the online map services of gdi.bonn.de offline. This also affects many pages of www.bonn.de, where temporarily no map services and overviews can be offered. The city administration asks for your understanding.

Property tax calculation is not affected by the changes. The situation is different for some spatial Open Data services that are technically based on the city map. Here, too, data can no longer be accessed for the time being.

Data on the current water level of the Rhine can be found under  this link (opens in a new tab).
