Corine Land Cover 2012 (raster 100m) version 18.5 accounting layer, Mar. 2017
CORINE Land Cover (CLC) data are produced from 1986 for European countries. Altogether four mapping inventories were implemented in this period, producing four status layers (CLC1990, CLC2000, CLC2006, CLC2012) and three CLC-change (CLCC) layers for three periods (1990-2000, 2000-2006, 2006-2012).
To eliminate several inconsistencies from the usage of 100m raster version of original CLC data in the accounting systems at EEA, like Land and Ecosystem Accounting (LEAC), which uses a 1km grid (CUBE) base for calculation, a harmonization method were elaborated for the CLC and CLCC data.
The applied solution for the harmonization combines CLC status and change layers in the 100m raster form in order to create homogeneous quality time series of CLC / CLC-change layers for accounting purposes. The so called "CLC accounting layers" fulfilling the relation: CLC-change = Modified CLC_ new status – Modified CLC old status. The modification method maximizes compatibility of “backdated” CLC status layers with CLC2012 and each other. However this simple solution causes several issues to be solved: (1) Modified CLC layers loose statistical comparability with original CLC layers, because of increased geometry; smaller than 25ha MMU features will appear locally where changes appear. In case of some CLC classes this causes significant differences. (2) “Fake features” are appearing in the backdated CLC status layers due to inconsistencies between CLC-change datasets.
CLC2012 is the fourth CORINE Land Cover inventory and took three years to finalize. A dual coverage of satellite images were used. Computer Assisted Photo-Interpretation (CAPI) was the dominating mapping technology. The number of countries using advanced (bottom-up) solutions has slightly increased. All of the EEA39 countries have participated within the official lifetime of the project.

Vector CLC database was provided by National Teams within original CLC1990, IandCLC2000 update, FTSP/CLC2006 update and CLC2012 projects. All features in original vector database were classified and digitised based on satellite images with 100 m positional accuracy (according to CLC specifications) and 25 ha minimum mapping unit into the standardized CLC nomenclature (44 CLC classes). European Corine Land Cover seamless databases represent the final product of European data integration.
All seamless vector layers were rasterized to the 100m resolution grid. MAXIMUM_COMBINED_AREA method was used for the rasterizing.
Methodology of harmonization to create CLC accounting layers:
The solution applied for the harmonization of CLC time-series is based on the idea to combine CLC status and change information in order to create a homogenous quality time series of CLC / CLC-change layers for account purposes fulfilling the relation:
CLC change = Harmonized CLC_ new status – Harmonized CLC old status.
Additional criteria of the realization were:
(1) Add more detail to the latest CLC status layer (CLC2012) from previous CLCC information and use this modified layer as a reference,
(2) Create previous CLC status layers by "backdating" of the reference, realized as subtracting CLCC based information for CLC2012.
Based on the above principles, the working steps of the creation of CLC accounting layers are as follows:
(1) Include formation information from CLC-change layers into current CLC2012 status by creating CLC2012 accounting layer.
(1a) Overwrite CLC2012 with first with code_2006 from CLC-change 2000-2006. Intermediate result: A1_CLC2012,
(1b) Overwrite F1_CLC2012 with code_2012 from CLC-change 2006-2012. Result: A2_CLC2012.
(2) Create CLC2006 accounting layer by including consumption information (code 2006 from CLC-change 2006-2012) into A2_CLC2012. Result: A1_CLC2006.
(3) Create CLC2000 accounting layer by including consumption information (code_2000 from CLC-change 2000-2006) into A1_CLC2006. Result: A1_CLC2000.
(4) Create CLC1990 accounting layer by including consumption information (code_1990 from CLC-change 1990-2000) into A2_CLC2000. Result: A1_CLC1990.
The harmonization was carried out on the version 18_5 of Corine Land Cover European database (RELEASE v18_5; dated 02/2016).
