  • 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 3D vectors for buildings are three-dimensional instances of the Building target category in the National Topographic Database (KMTK). The 3D vectors are produced with a high degree of automation from laser scanning data 5 p based on 2D vectors for buildings in KMTK. For the time being, data is available only from a few example areas, but the coverage will be extended to the whole of Finland as the laser scanning programme proceeds. The product belongs to the open data of the National Land Survey of Finland.

  • Paikkatiedon tiedostopalvelu (OGC API Processes) tarjoaa kyselyrajapinnan, jonka kautta voi hakea Maanmittauslaitoksen avoimia paikkatietoaineistoja tiedostopaketteina. Aineistot ovat samat, joita voi hakea käyttöliittymän kautta Karttapaikka-palvelun Lataa paikkatietoaineistoja -osiosta. Aineistojen tarkemmat tiedot ovat luettavissa tuotekuvauksista https://www.maanmittauslaitos.fi/kartat-ja-paikkatieto/aineistot-ja-rajapinnat/tuotekuvaukset Palvelu sopii esimerkiksi käyttöön, jossa on tarvetta hakea paikkatietoaineistoja koordinaateilla eli suorakaiteella (Bounding Box) tai polygonirajauksella. Karttapaikan Lataa paikkatietoaineistoja-osiossa nämä valinnat piirretään kartalla, mutta OGC API Processes -palvelussa koordinaatit voi syöttää kyselyparametreina. Hakuparametrit vaihtelevat aineistosta riippuen. Osaa aineistoista voi hakea myös karttalehden, kunnan tai teeman perusteella, tai koko Suomen alueelta. Palvelusta saatavat aineistot ovat Maanmittauslaitoksen avoimen tietoaineiston Nimeä CC 4.0 -lisenssin alaisia. Palvelu tarjotaan avoimena rajapintana, jonka käyttö on maksutonta.

  • 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.

  • The Topographic map is a dataset depicting the terrain of all of Finland. The key elements in it are the road network, buildings and constructions, geographic names, waterways, land use and elevation. The more precise levels of the Topographic map consist of the same map objects and map symbols depicted in the same way as in the familiar Basic map. Basic map raster is applicable to be used, for instance, as a base map for planning land use or for excursion and outdoor recreational purposes in mobile devices and in various Internet services associated with nature. When going over to the more general datasets in the Topographic map, the number and visualisation of objects and map symbols changes. The generalised small-scale Topographic maps raster are applicable to be used as approach maps in e.g. mobile devices and Internet services. The product belongs to the open data of the National Land Survey of Finland.

  • Control points and their coordinates and elevations define in practice the reference system for coordinates and elevations used in Finland. The NLS benchmark register contains information about nationwide control points and benchmarks. The marks are mainly horizontal and elevation control points in classes 1–3 measured by the National Land Survey of Finland. The product belongs to the open data of the National Land Survey of Finland.

  • The Background map is a dataset product series in raster format that depicts the whole of Finland and that is meant for web use as a background material for thematic data. Its key objects are road names, roads and railways, buildings and constructions, administrative borders, geographical names, waterways, land use and addresses of buildings (from Ryhti/Finnish Environment Institute). The product belongs to the open data of the National Land Survey of Finland.

  • 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.

  • 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 false colour. 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. 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.
