URBAN ATLAS

The Urban Atlas provides pan-European comparable land use and land cover data for Functional Urban Areas (FUA).

  • Urban Atlas 2006: 319 FUAs with more than 100,000 inhabitants
  • Urban Atlas 2012: 785 FUAs covering EU28 + EFTA countries + West Balkans + Turkey
There are several product layers which can be run through the QC Tool:
  • 1: Urban Atlas 2012 status (UA)… revised layer
  • 2: Urban Atlas 2018 status (UA)… reference layer
  • 3: Street Tree Layer 2018 (STL)
  • 4: Urban Atlas Change 2012-2018… change layer
