  • 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.

  • 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 available from all of Finland. The product belongs to the open data of the National Land Survey of Finland. From 2020 onwards, laser scanning data according to the laser scanning programme will be produced. The product description of the 'Laser scanning data 5 p' according to the scanning programme is available: https://www.maanmittauslaitos.fi/en/maps-and-spatial-data/expert-users/product-descriptions/laser-scanning-data-5-p. A spaced-out open dataset will be created from the new Laser scanning data 5 p: https://www.maanmittauslaitos.fi/en/maps-and-spatial-data/expert-users/product-descriptions/laser-scanning-data-05-p. The characteristics of this dataset correspond to the Laser scanning data 2008–2019 dataset.

  • 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.

    The Cadastral index map shows location data of real property units. They include boundaries, boundary markers, property identifiers, and unseparated parcels of real property units and other register units. The product is open data. You can take the product into use via the interface services or in file format in the Download geospatial data section on MapSite. You can read more about acquisition in the section Distribution and further information below. If you download the product with municipal boundaries on MapSite, it is good to know that parcels also include areas from the neighbouring municipality. You can make a more precise intersection in the client software, for instance with the Administrative areas product. The linear boundary data is, however, intersected according to municipal boundaries. Other attribute data related to properties are available in the Cadastre.

    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.

    NLS Orthophotos are an aerial photo dataset covering the whole of Finland. An orthophoto is a combination of several individual aerial photos. The geometry of the orthophotos corresponds to a map. The aerial photo data set in orthophoto format is available as - the most recent data set consisting of the most recent aerial photos available. The most recent data is usually 1–3 years old. - old aerial photos, consisting of data sets that are older than the most recent data set. The oldest aerial photos were taken in the 1930s. New data is added to the data set continuously. NLS Orthophotos are updated every 3 years (in Northern Lapland 12 years). Different versions of orthophoto products: - Ortophoto - Ortophoto, false colour - Ortophoto, forest ortho - Ortophoto, natural disasters In addition, there is an index map available presenting the year, when the newest photo was taken in each square. 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.

    Elevation model 2 m is a model depicting the elevation of the ground surface in relation to sea level. Its grid size is 2 m x 2 m. The dataset is based on laser scanning data, the point density of which is at least 0.5 points per square metre. The product's coverage is based on nationwide laser scanning. In some parts of the outer archipelago or the eastern border, the elevation model is not available. Elevation model 2 m is produced in two quality classes: the elevation accuracy in class I is on average 0.3 metres and the elevation accuracy in class II varies between 0.3 metres and one metre. The product belongs to the open data of the National Land Survey of Finland.

    National Land Survey's geographic names are available as interfaces and files. Interfaces and file products comprise of place name products and map name products. The place name products include data about approximately 800,000 named places and their names in different languages. Data about place are among others place type, plane location and height above sea level, and data about names are among others the spelling that has been checked by the Institute for the Languages of Finland and language (Finnish, Swedish, Northern Sami, Inari Sami or Skolt Sami. In the place name products, every place and its name or names appear only once. The map name products contain the place names that have been selected for the National Land Survey's nine standard map products and information about the cartographical presentation of them. The information includes the location of the name on the map, for instance the coordinates of the left lower corner of the map text, the direction and bending of the text as well as typographical information, such as font type, size and colour. The name of a particular place, such as a river, can appear several times in the same map product. The product is a part of the open data of the National Land Survey.
