The Thesaurus Project of the Geological Survey of Austria attempts the task of the construction of a controlled vocabulary for the semantic harmonisation of map-based geodata. The content-related realization of this project is governed by the Thesaurus Editorial Team, which consists of thematic experts from the Geological Survey of Austria. Currently there are 5 thematic thesauri available which reflect the basic information of geological maps: lithology, geologic timescale, geologic structures, geologic and tectonic units. All thesauri are available in both German and English* via an open web-application and standardised service interface.

With the development of semantically and technically interoperable geodata the Geological Survey of Austria implements its legal obligation defined by the EU-Directive 2007/2/EC INSPIRE and the national Geodateninfrastrukturgesetz GeoDIG, respectively.

*Note that some information or documentation might not be available in English yet.
