This data category requires a high level national map. To satisfy this category, the following minimum criteria must be met:

  • Scale of 1:250,000 (1 cm = 2.5km).
  • Markings of national roads
  • National borders
  • Marking of streams, rivers, lakes, mountains.
  • Updated at least once a year.

Data Location


Unsure how to answer the "Available for free" and "Machine-readable" criteria:

  • there is an online version which is free but not machine-readable (it's an online map)
  • detailed machine-readable versions are also available (as OGC WMS, OGC WFS services, etc.) but it is a paid service and it is not clear how to get access to them. here's the official publication with a list of fees:
