CORINE Land Cover data have undergone several quality controls. Geometrical accuracy is relatively good however some inconsistencies exist at the border between different countries (e.g. France and Belgium). The quality of LaCoast data is currently being controlled by the JRC. Results will be shortly known. As for the extension to accessing countries quality results look very satisfactory. Spatial adjustment method used was "rubbersheet".

- CORINE Land Cover version 1990 provides data which result from a visual analysis of LANDSAT and SPOT satellite images (mainly from 1987 to 1994) and interpreted with the support of ancillary data (such as aerial photographs, topographical maps, or ecological maps). The 44 classes nomenclature of CORINE Land Cover (and therefore EUROSION) is standardized for all Europe which makes comparison and aggregation at the European level easier. Note that CORINE Land Cover version 2000 has been developed by the European Environment Agency.

- LaCoast project. LaCoast is a research project undertaken in the mid 1990 under the lead of the Joint Research Centre (JRC) and aimed at quantifying the changes of land cover types in a 10 km land strip from the coastline. LaCoast uses CORINE Land Cover version 1990 as its reference dataset and track differences of land cover changes using LANDSAT satellite images from the mid-1970's .

- EUROSION was a project commissioned by the General Directorate Environment of the European Commission 2002-2004. EUROSION is extending the methodology of LaCoast to other European countries not currently covered by LaCoast. The same methodology was used to ensure consistency, easy comparison, and quick aggregation.
