The purpose of One Geology-Europe is to enable the sharing and accessibility of European geological data. The national geological institutes have a wealth of data assets which is often accessible only to specialists. In addition, these data have not been easy to understand so far, their use and inter-operability are difficult. These functions will be possible with One Geology-Europe.

 At European level, geology is a key dataset within the INSPIRE ((Annex II) European Directive. In fact, based on the knowledge it provides, European Directives are drafted and issued on groundwater and landscape monitoring (GMES, GEOSSand SEIS). Moreover, geology is essential to the forecasting and mitigation of landslides, subsidence, earthquakes, flooding and pollution.
