The Geological Survey of Finland (GTK) has carried out systematic aerogeophysical low-altitude surveys during the period 1972-2007. The flight altitude (main terrain clearance) has been 30-40 m with a nominal flight line spacing of 200 m. The standard flight lines chosen run North-South and East-West and follow the main geological trends. The distance between the measuring points along the survey lines has been 6-50 m. The geophysical parameters measured include Earth's magnetic field, the electromagnetic field and natural gamma radiation. Magnetic measurements determine the Earth's magnetic field strength (magnetic flux density), and the parameter obtained is the total magnetic intensity. The measurements have been made with one to three proton magnetometers until 1991 and thereafter with one or two cesium magnetometers. Most of the land area has been flown using two magnetometers.

Statistics Finland's Web Service is a WMS interface service through which the following data required by INSPIRE and national legislation on geographic information are available: 1) Statistical units: Regional divisions (municipality, major region, region, sub-regional unit, Regional State Administrative Agency (AVI), Centre for Economic Development, Transport and the Environment (ELY), electoral district) and grid 1 km x 1 km. 2) Non-profit and public services: Educational institutions (comprehensive schools, upper secon-dary general schools) 3) Production and industrial facilities: Production and industrial facilities 4) Population distribution by the regional divisions used in statistics and by 1 km x 1 km grids. Other data published: - Open data by postal code area (Paavo) - Population distribution by 5 km x 5 km grids The data are administered by Statistics Finland. The service is free of charge and does not require authentication or identification with a user ID and password. The general Terms of Use must be observed when using the data: http://tilastokeskus.fi/org/lainsaadanto/copyright_en.html.

DVV INSPIRE Buildings Theme Dataset is a dataset depicting the Buildings covering the whole of Finland. It contains the following INSPIRE feature types: Buildings The elements are updated weekly. The dataset is based on "Väestötietojärjestelmän rakennus- ja huoneistotiedot" by the Digital and Population Data Services Agency (Digi- ja väestötietovirasto). Id-attribute indicates the permanent building number for buildings (VTJ-PRT). The dataset is available via the DVV INSPIRE Download Service (WFS) for Buildings Theme and it can be viewed via the DVV INSPIRE View Service (WMS) for Buildings.

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 dataset is based on "Väestötietojärjestelmän rakennus- ja huoneistotiedot" by the Digital and Population Data Services Agency (Digi- ja väestötietovirasto). The dataset is available via the DVV INSPIRE Download Service (WFS) for Addresses Theme and it can be viewed via the DVV INSPIRE View Service (WMS) for Addresses.

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.
