NGU Superficial geology - OneGeology-Europe WP3. Mapscale 1:1 M. This service shows surface geology, structures and bedrock defined by rock types and ages. The areas of bedrock are also assigned to tectonic units. The map has been compiled using data acquired during several mapping campaigns carried out over decades, which was archived in digital format, published or prepared in manuscript form between 1989 and 2001. Due to variations in the quality of information gathered and the different scales used in different mapping campaigns, the level of accuracy in the underlying national database is variable. The database is designed for presentation at the 1:1M scale.

The Geological Map of Italy at a scale 1:1.000.000 is a service provided for the OneGeology-Europe project. The layers display geological units classified using the harmonized nomenclature for lithology, age and geological structure given by the attributes contained in the WP3 standard vocabularies.

The database for geological map of Romania at 1:1 000 000 scale had been built on the basis of geological map built by an authors team in 1978 and is organized in two layers (Geologic Unit – lithostratigraphy and Geologic Structure – geological boundaries and faults) and two tables. This has been modified for harmonization in to OneGeology Europe project.
