Geological mapping and the production of geological maps is one of the most fundamental tasks of a national geological survey organisation. The EuroGeoSurveys (EGS) community has for many years worked in EU co-funded projects to harmonise such maps across Europe. One of the flagship projects was the OneGeologyEurope project that ran between 2008 and 2010 producing a surface geological map dataset at a scale of 1: 1 million covering 21 European countries – a compilation that was subsequently supplemented by a number of additional countries. In the spring of 2016, a number of the underlying web services have been upgraded to be truly INSPIRE compliant. The EGDI is hosting these services, but also provides access to other geological map datasets from Europe such as the International Geological Map of Europe in scale 1: 5million (IGME 5000) and a cross-border 1: 100 000 geological map covering the eastern part of the Alps between Italy and Slovenia harmonised as part of the eENVplus project. All of these datasets are suited for different use cases.
The European data harmonisation projects and facilitation of INSPIRE Earth Science is undertaken by the Spatial Information Expert Group under EGS.
