Open spatial data

Nowadays a lot of spatial data is available, below are links to some important services in Finland and internationally.

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.
  • 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. 1:10 000 000
  • EuroGeographics, EuroGlobalMap, 1:1 000 000
  • GeoNames - place names

Satellite images

  • ESA:
  • NASA/USGS:
    • Landsat, resolution: 15-120m, revisit time 8 days or more, 7-11 channels, 1972 ->
      • GLS, Global Land Survey, selection of Landsat images from years: 1975, 1990, 2000, 2005 ja 2010.
    • MODIS provides continuous global coverage every one to two days, and collects data from 36 spectral bands. Resolution: 250-1000m. 1999 ->
    • EO-1, 10- to 30-meter multispectral and hyperspectral data, 2000-2017. Unregular capture times.
    • ASTER, resolution: 15, 30, 90m, 14 channels. Unregular capture times.
    • And many other thematic sensors.
    • These and other datasets can be downloaded from several services:
  • AWS Public Data Sets: Sentinel, Landsat, GLS, MODIS and more. Download of most images if for free for users, but for some (inc. Sentinel) download is on Requestor pays basis, ie downloading costs a little bit.

 

Digital Elevation Models

  • ESA, Copernicus DEM, 90m open to everybody, 30m global and 10m European DEM with restricted access, 2019
  • ESA, EU-DEM, only Europe, 25m.
  • JAXA, ALOS DEM, 30m.
  • Jonathan de Ferranti DEM, 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, SRTM, resolution 1'' (30m), 2000. 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.
  • Giuseppe Amatulli, Geomorpho90m - Global High-Resolution Geomorphometric Layers, 100m, 3'' and 7''

 

Digital Elevation Models including oceans
  • Columbia University, GMRT, is based on several sources, inc. ASTER GDEM ja Multibeam swath bathymetry data (100-m resolution). resolution: 1'' ja 100m (water).
  • NOAA, ETOPO1, two versions: according to bedrock or including also glaciers. Grid resolution: 1'. Includes also water areas.
  • BODC, GEBCO, bathymetry for the world's oceans. Grid resolution: 1' and 30''. 2008.

Climate

  • WorldClim, global weather dataset includes monthly minimum, maximum and average air temperature, precipitation and bioclim. Data is available in grid resolutions 30 arc seconds (about 1x1 km) and 2.5, 5 and10 arc minutes. There are available also modeled data sets about past and future.
  • CGIAR-CSI, Historic Climate Database, 1901-2006. Resolution: 30'. Clouds, different temperature statistics, precipitation etc.
