GeoE3 is a project co-financed by the Connecting Europe Facility of the European Union that will provide the vital connection between existing and emerging National, Regional and Cross-Border digital services. The action provides dynamic integration of high-value data sets and services (e.g. meteorological or statistical data) with geospatial features from existing national geospatial data platforms (e.g. building data or road network data). This simplifies meaningful analysis and visualization in a national and cross-border context. By enabling the Open Public Data Digital Service Infrastructure, GeoE3 develops fundamental services to better serve the European citizen by enhanced availability, interoperability, and integration of services.
