General vector data

  • OpenStreetMap – please be careful with the free data in Shape format. It does not include all the 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 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 scale.
  • EuroGeographics, EuroGlobalMap, 1:1 000 000 scale.
  • GeoNames – place names.
