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.

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.

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.

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.

The themes of the Topographic database and Topographic map raster series (scale 1:10,000) have been compiled into seven theme entities, theme rasters, required by the Inspire directive: hydrography, elevation, traffic network, land use, land cover, place names and buildings. In addition to the above, the theme rasters also include the municipal division, road names and map sheet division as separate themes. The theme rasters have not been implemented according to the imaging technology defined in the Inspire directive. They will be produced later. The product belongs to the open data of the National Land Survey of Finland.

Ortokuvien ja korkeusmallien kyselypalvelun (WCS) kautta voit hakea rasterimuotoisia ortokuvia ja korkeusmalleja. Palvelussa voit poimia haluttuja paloja aineistoista omalla aluerajauksellasi. Ortokuvien osalta palvelu sisältää Maanmittauslaitoksen väri-, vääräväri- ja mustavalkoisia ortokuvia eri vuosilta. Korkeusmalli on 2 m korkeusmallia, joka on tuotettu laserkeilausaineiston pohjalta. Korkeusmallia pystyy hakemaan palvelusta myös karkeammilla kuin 2m resoluutioilla. Tarjolla ovat seuraavat resoluutiot: 2 m, 4 m, 8 m, 16 m, 32 m, 64 m, 128 m, 256 m ja 512 m. Ortokuvat ovat saatavilla palvelusta GeoTIFF-formaatissa ja korkeusmalli GeoTIFF- tai ASCII Grid -formaatissa. Palvelun käyttäminen edellyttää perehtyneisyyttä paikkatietorajapintojen ohjelmalliseen hyödyntämiseen. Yksittäisten latausten tekeminen onnistuu myös selaimella. Ladatut tiedostot saat auki ja voit jatkokäsitellä paikkatieto-ohjelmalla. Toistaiseksi palvelua ei pysty käyttämään esimerkiksi QGIS -ohjelmalla. Aineistot ovat Maanmittauslaitoksen avoimen tietoaineiston Nimeä CC 4.0 -lisenssin alaisia. Palvelu tarjotaan avoimena rajapintana, jonka käyttö on maksutonta. Käyttäjä tunnistetaan API-avaimella.

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.

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.
