All freely accessible data of BAW may, in accordance with § 12a E-Government-Act (Act to promote electronic government (EGovG)), be re-used without any restrictions and without the need for compulsory registration provided that the source reference is indicated, as laid down in the GeoNutzV ordinance ("Verordnung zur Festlegung der Nutzungsbestimmungen für die Bereitstellung von Geodaten des Bundes: Ordinance to Determine the Conditions for Use for the Provision of Spatial Data of the Federation). As to the layout of source references, the BAW requests adherence to the following guidelines (cf. § 3 of the GeoNutzV ordinance):

  • The obligation to indicate the enclosed source references shall apply to any data and other services of BAW that are used without alteration. Source references must also be indicated even if extracts or excerpts are used or if the data format has been changed. Displaying the BAW logo shall be considered as meeting the requirement of source reference in meaning of the GeoNutzV ordinance.
  • In the event of more advanced alteration, processing, new design or other adaptation, BAW at least expects to be mentioned in a central list of references or in an imprint.
  • Indication of alteration according to the GeoNutzV ordinance may read as follows: "Data basis: Bundesanstalt für Wasserbau, gridded data reproduced graphically"; "Data basis: Bundesanstalt für Wasserbau, averaged over individual values", or "Data basis: Bundesanstalt für Wasserbau, own elements added".
  • If a service provided by BAW is used in a way that does not comply with its intended purpose, the enclosed source references have to be deleted. This shall especially apply to warnings for which there is no guarantee that they are delivered to all users at all times completely and without delay.

Wherever data or information from third parties is used for the generation of BAW-own products and services, BAW assures that it holds all necessary rights to do so.
