  description: |
      Contains administrative boundaries as linestrings (municipalities, counties, provinces, ...)
      Administrative regions are translated to their equivalent NUTS/LAU classification
      Fields indicate which NUTS-region is to the left and right of the linestring
  fields:
    nuts_level:
        The mininum NUTS/LAU classification this linestring is part of.
        NUTS only goes to 3 thus LAU 1 & 2 are mapped as NUTS 4 & 5.
         NUTS 0 = Countries
         NUTS 1 = Regions (e.g. Vlaams-brabant)
         NUTS 2 = Provinces (e.g. Limburg)
         NUTS 3 = Administrative arrondissements (e.g. Antwerpen, best to ignore these)
         NUTS 4 = Municipalities (e.g. Lummen)
         NUTS 5 = Villages/Suburbs (e.g. Linkhout)
