  • 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.

  • 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.

  • 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.

    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.

  • 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.

  • 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.

    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.

  • 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 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.
