    In order to offer public access to environmental data, Germany and Austria have developed a meta information system called Umweltdatenkatalog (UDK).

The new concept of the UDK is presented in detail addressing both the datamodel and the main functionalities as the UDK-Explorer, the Thesaurus-Navigator, and the GIS-viewer.
