OneGeology-Europe was an EU eContentPlus project with the purpose of developing a harmonised data model (based on existing international standards) for 1:1 million geological map data and serving these data for 21 countries through OGC-compliant web services in a multilingual portal in 18 languages.

The map has been further developed as part of the general EGDI intiative and is currently served by the Geological Survey of Slovenia.
