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.

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.

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.

The Plain map series is a simple, plain and readable dataset product series in raster format that depicts the whole of Finland. The product is meant to be used as a background map whose character changes to a guide map in large scales. Impaired vision has been taken into account when designing the product. The key objects presented on the map are roads and railways, road names, buildings and constructions, administrative borders, waterways and other geographical names. The road network, public buildings and texts have been especially emphasised. The most usual limitations of colour vision have been taken into account in the use of colours. 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.

Division into administrative areas (raster) is a dataset depicting the municipal Division of Finland. 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. Division into administrative areas products in raster format include municipal boundaries only. The product is a part of the open data of the National Land Survey.

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.

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.

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 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.
