  • 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 0.5 p has been spaced out from Laser scanning data 5 p's density of 5 p/m² to a density of 0.5 p/m². Laser scanning data 0.5 p is open data, and from 2020 onwards, it will be collected according to the national laser scanning programme (in Finnish): https://www.maanmittauslaitos.fi/laserkeilaus-ja-ilmakuvaus. For the time being, it is available only from certain parts of Finland. The product belongs to the open data of the National Land Survey of Finland.

  • 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.

  • Hillshade (elevation model) is a raster dataset visualising the elevation of the terrain. There are five product versions available in which the pixel sizes are 2, 8, 32, 64, 128 and 512 metres. Pixel size 2 m has been produced of the dataset Elevation model 2 m. The other sizes have been produced of the dataset Elevation model 10 m. The material does not contain elevation values; it is a greyscale image that visualises the direction and steepness of hills. The product belongs to the open data of the National Land Survey of Finland.

    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.

  • Paikkatiedon tiedostopalvelu (OGC API Processes) tarjoaa kyselyrajapinnan, jonka kautta voi hakea Maanmittauslaitoksen avoimia paikkatietoaineistoja tiedostopaketteina.

    The Topographic database is a dataset depicting the terrain of all of Finland. The key objects in the Topographic database are the road network, buildings and constructions, administrative borders, geographic names, land use, waterways and elevation. Aerial photographs, scanning data and data provided by other data providers are utilised in updating the Topographic database. The updating is done in close cooperation with the municipalities. Field checks in the terrain are also needed to some extent, mostly as regards the classification of features. The topographic database is used in the production of other map products and in various optimisation tasks. The product belongs to the open data of the National Land Survey of Finland.
