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

  • 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:

I decided to give credit for having the data in machine readable format, but deducted points for not accessing this data for free.
