Note: The methodology used in the Global Open Data Index has changed over time; significantly so between 2015 and 2016. For this reason, the results are not directly comparable over time.

What data is expected?

A geographical map of the country including national traffic routes, stretches of water, and markings of heights. The map must at least be provided at a scale of 1:250,000 (1 cm = 2.5km). Geographic information is instrumental for many use cases, including the mapping of unemployment statistics or demographics, as well as journey planning. See our methodology section for more information.

  • Scale of 1:250,000 (1 cm = 2.5km)
  • Markings of national traffic routes
  • Markings of relief/heights
  • Markings of water stretches
  • National borders

How open is the data?

IGN produces and offers a wide range of map data products from raster data (images) to vector format data or even 3D data. Low detailed maps are available as open data, together with some specific layers such as administrative boundaries. For instance, raster maps are available as open data at 1:100000 scale. However, map with key infrastructure in vector format is not available as open data but can be obtained against a license fee. IGN also give access to some of its data through a Web Map Service (WMS).
