  • 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 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.

  • 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.

    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 is available as versions with different coverage areas through-out the whole country but not as comprehensive. New data is added to the dataset continuously. Eleva-tion model 10 m is available as a version that covers the whole of Finland. 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.

    Elevation model 10 m depicts the elevation of the ground surface of the whole of Finland in relation to sea level. Its grid size is 10 m x 10 m and the accuracy of elevation data 1.4 metres.

  • Sisävesien (järvet, joet) syvyysaineisto perustuu pääosin ympäristöhallinnon tekemiin syvyysluotauksiin. Luotauspisteaineistosta on SYKEssä johdettu syvyyskäyrät ja -alueet sekä järven maksimisyvyyspiste- aineistot. Järvien luotaus- ja maksimisyvyyspisteisiin sekä syvyysalueisiin on yhdistetty fysiografiatietoja SYKEn ylläpitämästä järvirekisteristä. Nämä syvyyskäyrät toimitetaan Maanmittauslaitokseen, jossa ne tallennetaan osaksi maastotietokantaa ja edelleen julkaistaan maastokartoista. Aineisto kuuluu SYKEn avoimiin aineistoihin (CC BY 4.0). Aineistosta on julkaistu INSPIRE-tietotuote. Lisätietoja: http://geoportal.ymparisto.fi/meta/julkinen/dokumentit/Syvyys.pdf The Lake and River Depth Profiles dataset includes information on depth profiles of lakes and rivers and is mainly based on the depth measurements done by the national environmental administration. The bathymetric lines and the depth areas are produced from separate measurement point information. Bathymetric information and the maximum depth points have also information on physiography from the lake database “Järvirekisteri” maintained by SYKE. These bathymetric lines are delivered for The National Land Survey of Finland where they are combined with the base map dataset (Maastotietokanta) and published as maps.

  • The Topographic map series 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 series 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 series, 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.

    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.

  • National Land Survey's Topographic map series 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 series in vector format is produced by generalising from the Topographic database. Topographic map series 1:250,000 is produced by generalising the dataset 1:100,000. Topographic map series 1:1,000,000 is produced by generalising the dataset 1:250,000. Topographic map series 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 Topographic map series in vector format can be used for the production of other map products, e.g. approach maps or maps on a regional or national level The product belongs to the open data of the National Land Survey of Finland.
