Open spatial data

There is a lot of spatial data available on the Internet, here you can find a lot of links to most important services in Finland and internationally.

 

Finnish spatial data services

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

  • 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.
  • Open spatial data is an (out-dated) list of links to open spatial data sets and web services to spatial data

Data download services

General vector data

  • OpenStreetMap, please be careful with the free data in Shape format. It does not include all features and has limited support for big or complicated polygons. For example all big lakes are missing and likely all holes in polygons are missing. Use rather data in pbf format. For changing format you may use QGIS or OGR (look for examples here).
  • EuroGeographics,  EuroGlobalMap (1:1 000 000).
  • NGA (National Geospatial-Intelligence Agency), VMAP, general vector data produced in 1991-93. VMAP0 data is in scale 1:1 000 000 and is available globally. 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.
  • WWF, Global Lakes and Wetlands Database (GLWD), lakes, rivers and wetlands. 2004. Map scale: 1:1 000 000 to 1:3 000 000.
  • NOAA, GSHHG, global coastlines, rivers, lakes and country borders, 2013.

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.

    • 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 metropolitan 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).
