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.

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.

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.

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.

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.

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 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.

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.
