Training area information

See this file for more information on:

  • Available LCZ classes
  • Number of training areas per LCZ class
  • Average / Total surface area (km2) per LCZ class
  • Average perimeter (km) per LCZ class
  • Average shape per LCZ class
  • Average number of vertices per LCZ class

LCZ map & Accuracy


The final filtered LCZ map is produced using all training areas and input features. Corresponding overall accuracies are:

  • OA: 0.84
  • OAu: 0.69
  • OAbu: 0.98
  • OAw: 0.97
Underlying and additional datafiles: original training areas, geotif, kmz, average confusion matrix over all bootstraps, boxplot figure with accuracies, and suspicious training areas (polygons / points).
