Open data


Paikkatietoikkuna

National Land Survey's Paikkatietoikkuna is a central place for discovering Finnish spatial data sets. It includes:

  • Open spatial data is a list of links to open spatial data sets and interface services to geographic information.
  • Map window can be used to view maps and browse geographic information.
  • Metadata search can be used to search for information about spatial data sets and geographic information services.


International services

Metadata services

  • European comission, INSPIRE Geoportal
  • Spatineo, catalogue of WMS, WMTS and WFS services, tens of thousands of services from whole world, also a lot of Finnish services.
  • European Environment Agency, Data and Maps, a lot of data related to environment from all Europe, for example: Natura areas, CORINE land cover, drainage basins, digital elevation model, data about water and air quality etc.
  • FAO, GeoNetwork.
  • National Snow & Ice Data Center (USA), Scientific Data Search, inc. 99 global data sets, besides ice and snow also a lot of other related datasets.
  • EDENext, Data Archive, the data spans a wide number of categories but mainly collated for use in research of vector borne disease epidemiology. Archive inlcudes data only for EDENext research area = Europa and North-Africa. Vegetation, climate, population etc.
  • Robin Wilson, Free GIS Data, a very long list of open GIS data, at the end also country spesific lists.

VMAP1 is in scale 1:1:250 000 and is for free available only from certain parts of world, for example from USA and Russia. More information may be found from Wikipedia. The data is originally in VPF format, in more practical shape format the data can be downloaded from GIS-Lab pages: VMAP0 and VMAP1.
  • Natural Earth, general vector data: coast lines, contours, rivers and lakes, glaciers, country borders etc. There are available also designed raster maps suitable to be used as background maps. The map scale is 1:10 000 000.

    • EO-1, 10- to 30-meter multispectral and hyperspectral data from the Earth Observing-1 (EO-1) Extended Mission, 2000 to present.
    • MODIS provides continuous global coverage every one to two days, and collects data from 36 spectral bands. Resolution: 250-1000m. 1999 -> Wide range of different datasets.
  • NASA, Reverb, all NASA's Earth Science data, inc. Landsat, EO-1, MODIS and a lot of others.
  • NOAA, National Oceanic and Atmospheric Adminstration, inc:
    • AVHRR, he Advanced Very High Resolution Radiometer (AVHRR) is a cross-track scanning system with five spectral bands having a resolution of 1.1 km and a frequency of earth scans twice per day, 1979 - present.
  • JRC, Image2000, CORINE land cover project's satellite images. This service requires registration, which may take several days.
  • NASA, Blue Marble, resolution: 500m. A separate image for each month of the year. Nice colors, suitable as background map.
  • NASA ja METI, ASTER, resolution: 15, 30, 90m, 14 channels. All products are not open, from archive you may find still also open images. Some products, for example L1A images, are available only for educational use, if application is approved. For educational and scientific use also new images may be ordered.
  • CNES, SPOT, images have not been available for free, but on 23.1.2014 was made a decision, that images older than 5 years, will be available for non-commercial use. Download service is promised for the end of year.

Digital Elevation Models

  • ESA, De Montfort University, ACE2, resolution: 3" (90m), 30" ja 5'. Based on STRM data, but has been corrected and filled, if the original data has been missing or is wrong. Besides the height the data includes for each grid the data source and accuracy estimation.
  • Jonathan de Ferranti, resolution3'' (90m), Based on STRM data, but has been corrected and filled, if the original data has been missing or is wrong.
  • NASA and NGA, STRM, resolution 3'' (90m), 2005. Available only for: 56° S ... 60° N, for Finland only southern coast is available.
  • USGS, GMTED2010, resolution: 30'', 15'' ja 7.5''.
  • ASTER GDEM, resolution 1'' (30m), 2009. Available for: 83° S ... 83° N. Please note, that althought this dataset has smallest grid size, it inlcudes a lot of errors and often is not more precise than ACE2 or STRM. 
  • GDEx user interface provides ASTER GDEM and STRM data, enables defining area and format for the data download.

Interface services


For ArcGIS users

  • ESRI ArcGIS.com ArcGIS Server interface services may be used with ArcGIS products.
    • Aineistot.esri.fi maps, several datasets about Finland, inc. background maps, administrative borders, population, buildings, addresses etc.
    • Basemap maps, that are especially easy to use from ArcMap. The best content about Finland is available from these layers:
      • OpenStreetMap, exact road map, quality varies from place to place. No use restrictions.
      • Imagery, satellite imagery, from metropolian area very exact images, otherwise about from scale 1:75 000. No use restrictions.
      • Topographic map, available from scale 1:5000. Hill-shading and in more detailed scales also contours. No use restrictions.

      • DeLorme World Basemap, topographic map with contours, from scale 1:300 000.
      • National Geographic Basemap
    • Landsat satellite images, mm. False Color/Near Infrared 1975-2005, Agriculture 1990-2005, Landsat NDVI Change, Landsat Time Enabled Imagery, Healthy Vegetation 1990-2005, Atmospheric Penetration 1990-2005, Vegetation Analysis 1990-2005, Land / Water Boundary 1990-2005, Shortwave Infrared 1990-2005.
    • Open data from Finland - Avoimia paikkatietoaineistoja Suomesta, this group includes open datasets from Finland.
    • Attention! ArcGIS.com datasets may be used in ArcMap also in EUREF-FIN or KKJ coordinate system, but it is a lot slower and also the image quality is worse. Use rather this coordinate system: Predefined -> Projected Coordinate Systems -> World -> WGS 1984 Web Mercator (Auxiliary Sphere).
