The Superficial deposits of Finland 1:200 000 (sediment polygons) contains data produced from the whole of Finland during the period 2002-2009. The data set can be used in regional planning, in military defence, in soil mapping (EU) and in joint mapping projects in various areas. The mapping scale has been 1:50 000-1:200 000. In compiling the medium-scale data set, generalised 1:20 000, 1:50 000 and 1:100 000 superficial deposits maps have been used and a new map product at a scale of 1:200 000 that is based on interpretation and field mapping. The minimum size of the sediment polygons is about six hectares. Exceptions are glaciofluvial, marginal till and hummocky moraine deposits, which are presented in the data set as areas with a surface area greater than two hectares. The blanketing peat overburden has been described in the new map product as a peat-covered area (0-0.3 m of peat), thin peat (0.3-0.6 m of peat) and thick peat (over 0.6 m of peat). Peat-covered areas, stone fields and uncovered bedrock areas have been added to the new production map by generalising the corresponding polygons in the terrain database of the National Land Survey of Finland (NLS). In connection with the generation of new production map, field observations have been gathered on the overburden thickness and the stratigraphic sequence at a depth of one metre as well as on rock exposures. Coordinate reference system of the Superficial deposits of Finland 1:200 000 (sediment polygons) 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.
The Regional Stream Sediment Geochemical Mapping data set gives information on the elemental concentrations in organic sediments of small headwater streams. The samples have been taken from small headwater streams (catchment area under 30 km2) in the late summer of 1990. Sampling has been repeated for about every fourth point during the years 1995, 2000 and 2006. The number of samples was 1162 in 1990 (at a density of one sample/300 km2), 286 in 1995, 286 in 2000 and 249 in 2006. The data set covers the whole of Finland. Stream water samples have also been taken at the same time. Sampling, processing and analysis methods have been described in the Geochemical Atlas of Finland, Part 3, p. 27-30 (Lahermo et. al 1996). Field observations, coordinates and element concentrations determined from samples have been made into a database, in which each record represents one sample point. The data for each sampling year have been recorded on different tables. The method of analysis is referred to with a four-character method code. The codes are as follows: 503H = mercury determination using the cold vapour method 503P = nitric acid extraction in a microwave oven, measurement with ICP-AES 503M = nitric acid extraction in a microwave oven, measurement with ICP-MS 820L = carbon, hydrogen and nitrogen determination with a LECO analyser. The element concentration data include a numerical concentration value (as mg kg-1 or ppm) and possibly a check mark. The concentration is recorded as a variable, which has a name that comprises the chemical symbol for the element and the code for the method of analysis. For example AS_503M is arsenic (As) concentration, which is determined with the ICP-MS method (503M). The next variable has a check mark, for example AS_503MT. If the numerical value following the check mark is ‘>’ or '‘<’ then the number recorded in the concentration field is the determination limit of the chemical analytical method used and the actual concentration is less than this value. If the check mark is an exclamation mark (!), the analytical result is smaller than the determination limit of the analytical method use but the (unreliable) value obtained with the measuring instrument has been entered in the database. There is no data are if the check mark is a 'x'. The original purpose of the Regional Stream Sediment Geochemical Mapping data set was national general geochemical mapping and the basic assessment of environmental state. Other uses are, for example, the assessment of changes in environmental state and determination of the baseline concentrations of stream sediments.
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 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.

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 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.
