The Plain map series is a simple, plain and readable dataset product series in raster format that depicts the whole of Finland. The product is meant to be used as a background map whose character changes to a guide map in large scales. Impaired vision has been taken into account when designing the product. The key objects presented on the map are roads and railways, road names, buildings and constructions, administrative borders, waterways and other geographical names. The road network, public buildings and texts have been especially emphasised. The most usual limitations of colour vision have been taken into account in the use of colours. The product belongs to the open data of the National Land Survey of Finland.

The themes of the Topographic database and Topographic map raster series (scale 1:10,000) have been compiled into seven theme entities, theme rasters, required by the Inspire directive: hydrography, elevation, traffic network, land use, land cover, place names and buildings. In addition to the above, the theme rasters also include the municipal division, road names and map sheet division as separate themes. The theme rasters have not been implemented according to the imaging technology defined in the Inspire directive. They will be produced later. The product belongs to the open data of the National Land Survey of Finland.

An aerial photograph is a photograph of the terrain taken from an aeroplane. The images are vertical photographs applicable to be used in mapping. The aerial photographs are reprocessed into dimensionally accurate images called orthophotos. Aerial photographs are available since the 1930s, depending on the area. Aerial photographs are available in black and white, colour and infrared. The size and accuracy of aerial photos depend on the camera, photography scale and altitude or ground sample distance (GSD). The product belongs to the open data of the National Land Survey of Finland. Aerial photographs can be ordered by pieces that cover a certain area. The latest orthophotos based on the aerial photographs can be downloaded free of charge from the File service of open data.

The map sheet division is a system created for printing maps, which covers map sheet codes, map scales and map sheet sizes. The map sheet division is a system created for printing maps, which covers map sheet codes, map scales and map sheet sizes. Today, map sheet division is also used for other purposes. It is also possible to download other NLS datasets in addition to maps in accordance with map sheet division. The map sheet division TM35, which is based on the projected coordinate reference system ETRS-TM35FIN is in use today. Before 2007, a map sheet division that was based on the KKS coordinate reference system was used. The TM35 map sheet division consists of 7 different grid sizes, the smallest scale is 1:200,000 and the largest is 1:5000. An explanation of how the grids are further split into more detailed grids and the principles of map sheet numbering is on the National Land Survey website (in Finnish) https://www.maanmittauslaitos.fi/kartat-ja-paikkatieto/kartat/osta-kartta/nain-loydat-oikean-karttalehden. The attribute data of the grids include map sheet number, the area of a square on the grid, perimeter and the coordinates of the centre of the square. The map sheet division is available as a file in vector format and through our contract-based WMTS service in raster format. In addition, you can view it in the geoportal Paikkatietoikkuna. The product is a part of the open data of the National Land Survey.

Elevation zones is a raster dataset that visualises elevation of the terrain. The product covers the whole of Finland. There are four product versions available in which the pixel sizes are 32, 64, 128 and 512 metres. The dataset does not contain elevation values; it is a colour image that visualises the height of the terrain above sea level as zones. The sea is shown in light blue in the elevation zone. The product Elevation zones is available as a version that covers the whole country and as versions that cover a certain area. The product belongs to the open data of the National Land Survey of Finland.

Division into administrative areas (raster) is a dataset depicting the municipal Division of Finland. The dataset Municipal Division is produced in scales 1:10,000, 1:100,000, 1:250,000, 1:1,000,000 and 1:4,500,000. The data included in the dataset in scale 1:10,000 are taken from the Cadastre. Regarding other scales, municipal boundaries have been generalised to suit the scale in question. Division into administrative areas products in raster format include municipal boundaries only. The product is a part of the open data of the National Land Survey.

Division into administrative areas (vector) is a dataset depicting the municipalities, regions, Regional State Administrative Agencies, and the national border of Finland. The Division into administrative areas products in vector format contain the number codes of the municipalities, the names of the municipalities in both Finnish and Swedish as well as municipal boundaries and municipal geographical areas. In addition, the products include the corresponding information about the regions, the Regional State Administrative Agencies, and the nation as well as a specification of the municipality's area into land and water area. The municipality's area is not included in the XML/GML and GeoPackage format. The dataset Municipal Division is produced in scales 1:10,000, 1:100,000, 1:250,000, 1:1,000,000 and 1:4,500,000. The data included in the dataset in scale 1:10,000 are taken from the Cadastre. Regarding other scales, municipal boundaries have been generalised to suit the scale in question. The product is a part of the open data of the National Land Survey.

National Land Survey's Topographic map in vector format is a dataset depicting the terrain of all of Finland. The most important elements are the road network, administrative borders, preservation areas, population centres, geographic names, waterways, land use and elevation. The largest scale level (1:100,000) of the Topographic map in vector format is produced by generalising from the Topographic database. Topographic map 1:250,000 is produced by generalising the dataset 1:100,000. Topographic map 1:1,000,000 is produced by generalising the dataset 1:250,000. Topographic map 1:4,500,000 is produced by generalising the dataset 1:1,000,000. The geographic names have been generalised from the geographic names in the Geographic Names Register to map names suited to the scale in question. The administrative borders in the Municipal Division of each scale are used as administrative borders. The product belongs to the open data of the National Land Survey of Finland.

Laser scanning data refers to three-dimensional point-like data depicting the ground and objects on the ground. Each point is provided with x, y and z coordinate information. Laser scanning data is collected i.a. for updating elevation models, creating 3D geometries of buildings, mapping flood risks, and collecting information about forest resources. The terms of use must be approved to use laser scanning data.
