Lack of spatial soil data in digital form has been a primary obstacle in establishing European policies on land use and environmental protection. Abundant data on soil characteristics exist in Finland but have been scattered among various sources, making it difficult for authorities to make country-wide presentations and predictions.The objective of the project was to create georeferenced soil map and database according to the instructions of the European Soil Bureau using data from existing databases and collecting some new data. The basis of the work was a geological map of quaternary deposits, which describes the soil at a depth of 1 metrem (parent material) according to the Finnish classification based on the concentration of organic matter and the texture of mineral material. Primary research topics included generalization methodology of soil polygons with GIS technology, calculation of soil characteristics needed in the database and computerizing the existing non-digital soil information. It was proved that aerial geophysics can be used for separation of shallow peats from deep peat soils and muddy soils and other wet areas can be identified. Soil names according to the FAO/Unesco system and the World Reference Base for Soil Resources (WRB-2014) were derived from the soil names of the Finnish soil classification system and geophysical data. Soilscape (Soil Mapping Units) of Finland with WRB-2014 soil classification, intented to be used in European scale e.g to delineate risk areas mentioned in soil framework directive proposal.

The 1:100 000 scale bedrock map data of the Geological Survey of Finland (GTK) include material produced during 1948-2007 for the needs of the mapping of mineral resources, for the sustainable exploitation of aggregate resources and for scientific research. These data include lithological information as polygons, bedrock observation points and drilling sites as well as essential tectonic observations, and information on lithological primary structures, ore minerals and metamorphic index minerals. Some 1:100 000 map sheets give both stratigraphical information as well as lithological data. An explanatory text accompanies most map sheets.

The Rock Geochemical Database of Finland data set describes the concentrations of major and trace elements in the bedrock of Finland. In all, 6544 samples were analysed for the total and partial concentrations of 57 elements using several different methods (XRF, ICP-MS, ICP-AES, GFAAS). The samples were taken during 1990-1995 with a mini-drill from rock that was as unaltered as possible. The sampling density varies between one sample per 30 km2 and one sample per 120 km2. The chemical analyses of the data were performed during 1992-2001. The reproducibility of the analytical results and the analytical drift were estimated using 375 duplicate sample pairs. The lowest reliable concentration was determined for each element and analytical method. In addition to the chemical concentrations, the database contains spatial data and several geological attributes for each sample. The data set and its manual were published in 2007 and they are available via the web site of the Geological Survey of Finland (GTK).

The data set relating to overall mapping of national peat resources contains by focus area those mires over 20 ha in extent that are most important from a peat production perspective. Since 1975 additional smaller areas have been included as required. For each mire, there are data on mire type, peat type, peat reserves, peat physical properties, mires that are suitable for peat production, peat quality and exploitable peat reserves. This information is published in municipality-specific peat investigation reports that present general information on each mire investigated and their applicability to energy, horticultural and environmental peat production as well as to protection purposes, among other uses.

The Superficial deposits of Finland 1:1 000 000 is based on 'Quaternary Deposits of Finland and Northwestern Part of Russian Federation and their Resources (Sheet 1, Western part)' mapping data. This data is also based on the 1984 map 'Quaternary Deposits of Finland' (1:1 000 000) in the “Geologia” (Geology) folio of the Atlas of Finland, 5th edition (123-126, 1990). Joint scientific and technical planning for the map of the 'Quaternary Deposits of Finland and Northwestern Part of Russian Federation and their Resources' was begun in 1987 while work on the map started in 1988. No field mapping was done for the map, rather the 1:1 000 000 Quaternary map printed in 1984 was supplemented with new data partly obtained from rock aggregate studies and partly from information on superficial deposits gathered in other superficial mapping projects. The map 'Quaternary Deposits of Finland and Northwestern Part of Russian Federation and their Resources' was printed in 1993. The map shows the superficial deposits with colours and symbols and these are classed according to their mode of geological development. The deposit classes are as follows: pre-Quaternary bedrock exposures (no Quaternary layers); boulder field, physically weathered bedrock; gravelly and sandy till; silty till; clayey till; hummocky moraine ; moraine complex; esker, delta, sandur, sorted marginal formation; interlobate formation (esker); till-covered esker / other till-covered gravel and sand deposit; gravel and sand deposit peripheral to eskers; littoral gravel and sand deposit; fluvial deposit; homogeneous clay and silt deposit; layered (varved) clay and silt deposit; peat deposit. Additionally, drumlins, end moraines, aeolian deposits, and sites of gravel, sand, clay and peat extraction as well as gold panning areas have been indicated with symbols. The data set was converted to a digital format to meet the needs of the OneGeology-Europe Project for a printed map in 2009. This data did not include drumlins, end moraines, aeolian deposits, and more important sites for the exploitation of superficial deposits (sites of gravel, sand, clay and peat extraction as well as gold panning areas). In accordance with the 1984 Quaternary map (1:1 000 000) the minimum size of the deposit polygon is generally one square kilometre. In nature the size of superficial sedimentary deposits is usually smaller than one square kilometre and therefore the most common deposit type in the area is shown in the polygon. In places, deposits smaller than a square kilometre that are significant from a superficial perspective have been noted. As a rule, the narrowest point of the deposit polygon was 0.5 km and in important cases, for example on eskers, 0.3 km. As an exception, the size of small eskers has been exaggerated. Coordinate reference system of the Superficial deposits of Finland 1:1 000 000 was transformed in October 2013. The transformation from Finnish National Grid Coordinate System (Kartastokoordinaattijärjestelmä, KKJ) Uniform Coordinate Frame to ETRS-TM35FIN projection was done by using the three-dimensional transformation in accordance with the recommendations for the public administration JHS154. The water layer which were used in the OneGeology-Europe project was replaced in 2015 with the more accurate water layer of the Topographic database 1:55 0000-1:500 000 (DVE3) from ICT Agency HALTIK.

Bedrock of Finland 1:200 000 is a unified bedrock map dataset covering the whole Finland. It has been compiled by generalising the scale-free bedrock map feature dataset. The dataset consists of a lithological/stratigraphic geological unit polygon layer and linear layers, in which faults, diverse overprinting lines and dykes are represented. The dataset also includes an origin of the data and a quality estimation of the data polygon layers. The stratigraphic geological unit polygon layer includes lithological coding, geological time period and hierarchical lithostratigraphical or lithodemic classification as attributes in accordance with the Finnish database for stratigrafic geological units (Finstrati). The line layers have their own hierarchical classification. The data are at 1:200 000 scale, which indicates that the main part of the scale-free data have been generalised to correspond to a product at a scale of 1:200 000. Those areas where the source data is coarser than 1:200 000 have not been generalised. Coordinate reference system of the dataset was transformed in March 2013. The transformation from Finnish National Grid Coordinate System (Kartastokoordinaattijärjestelmä, KKJ) Uniform Coordinate Frame to ETRS-TM35FIN projection was done by using the three-dimensional transformation in accordance with the recommendations for the public administration JHS154.
