Elevation zones

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.

Topographic map series (vector)

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.

Laser scanning data 2008 – 2019

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 collected i.a. in order to produce elevation models and collect information about forest resources. Laser scanning data is available from all of Finland. The product belongs to the open data of the National Land Survey of Finland. More information: Topographic data and how to acquire it http://www.maanmittauslaitos.fi/en/maps-and-spatial-data/expert-users/topographic-data-and-how-acquire-it 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.

Control points

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 5 p

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 collected i.a. for updating elevation models, creating 3D geometries of buildings, mapping flood risks, and collecting information about forest resources. Currently Laser scanning data 5 p is available only from certain parts of Finland. From 2020 onwards, data will be collected according to the national laser scanning programme.

Elevation model 2 m

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.

Hillshade

Hillshade 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 (old versions in PNG format and pixel sizes 10, 40, 80, 160 and 640 metres are still available through 2016). Pixel size 2 m has been produced of the dataset Elevation model 2 m and it does not cover the whole of Finland. The other sizes have been produced of the dataset Elevation model 10 m and they cover the whole country. 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.

Municipal Division

Municipal Division is a dataset depicting the municipal division in the whole of Finland. The Municipal Division dataset 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 cadastral registry. Regarding other scales, municipal boundaries have been generalised to suit the scale in question. The Municipal Division dataset is available as products both in vector and raster format. The products in vector format contain the number codes of the municipalities, the names of the municipalities in both Finnish and in Swedish as well as municipal boundaries and municipal geographical areas. In addition, the vector product includes the corresponding information about the regions, the State Administrative Agencies and the nation as well as a specification of the municipality's area into land and water area in MapInfo and Shape format. Products in raster format include municipal boundaries only. The product belongs to the open data of the National Land Survey of Finland.

Geographic names

The GML file products containing geographic names 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 file products containing geographic names are GML files whose contents are equivalent to the interface products in the Geographic names search service (WFS). One file always contains the data about the entire country. There are two place name products (Places and Place names), nine map name products, one for each map product (map scale). The geographic names products are available for downloading on the National Land Survey's File service of open data https://tiedostopalvelu.maanmittauslaitos.fi/tp/kartta/?lang=en

Elevation model 10 m

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. The product belongs to the open data of the National Land Survey of Finland.
