The first version of the contiguous digital map was compiled by Š. Káčer et al.(2005) under the terms of the geological project Digital Geological Map of the Slovak Republic at a scale of 1: 50 000. In addition to areal, line and point information, the following separate layers are available: a list of the background documents, classification of the data in terms of quality, a review of the scheme used for classification of geological units and structures. The areal information provided on the digital map includes: the unified legend and the original legend showing the characteristics and occurrence of individual lithotypes across the whole territory of Slovakia.

The GEO_200k_RO dataset has been created by vectorization of the paper map series: Geological Maps of Romania at a scale of 1 : 200 000, created during the years 1960-1969. This dataset was digitally processed using ArcGIS software as ESRI geodatabase format.

The GEOCR500 dataset was processed completely digitally in ArcGIS 9.1 and integrated within a regional geographic information system.

Geological Map of the Western Carpathians and Adjacent Areas at a scale of 1 : 500 000 compiled by J. Lexa et al.( 2000). The map contains both polyline and polygon layers. The basis used for the compilation of this map is the Geological Map of the Slovak Republic at a scale of 1:500 000, compiled by A. Biely et al.(1996) with amendments derived from the geological maps of the neighbouring countries.

The Geological Map of Finland depicts the main features of bedrock geology in Finland. In this dataset bedrock areas are classified according to rock types and ages. The dataset is an improved version of the Geological map of the Fennoscandian Shield. The legend has been revised in cooperation with the geological surveys of Sweden and Norway.

The dataset incorporates the main features of the bedrock geology in Norway. Areas of bedrock are classified according to rock type and age. Dyke swarms, tectonic structures, impact sites, and basalts are also shown. 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 and therefore the level of accuracy is variable.

Database containis a overview geological map of the Czech Republic at a scale of 1: 2,500,000 (schema) in English.

Geological Map of the Czech Republic 1 : 500,000 published in 2007, modified to be INSPIRE-compliant (cut-out for the area of the Czech Republic, harmonized data).

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.

Geological Map of the Mirofillon area, scale 1:50 000. The map shows polygonal and selected linear geological information sourced from the published IGME 1:50000 scale map of Greece. Geological units are identified using the 1G-E vocabulary that may differ from that on the printed maps. Τhe original data were published in the frame of the program for the compilation of the Geological Map of Greece, scale 1:50 000. The geological mapping has been carried out by K. Manakos, during 1981-1983. Micropaleontologic determinations : Dr. V. Skourtsi-Koroneou. IGME licensing terms and conditions apply to external use of the data.
