General description

This script visualises CORINE Land Cover (CLC) Accounting Layers according to the official CORINE Land Cover color scheme. CLC Accounting Layers are CLC status layers modified for the purpose of consistent statistical analysis in the land cover change accounting system at EEA.

For more details about the classes, please see the official CORINE Land Cover nomenclature guidelines or the illustrated nomenclature guidelines document.
