The mapping of ecosystems is here considered at the scale of habitat/biotopes and partly on landscape level. Ecosystem mapping is the spatial delineation of ecosystems following an agreed ecosystem typology (ecosystem types).
The basic geometric reference for the mapping exercise is CORINE Land Cover transformed into the 100*100 m grid (using the CORINE land cover value of the pixel centroid as pixel class label). CORINE Land Cover classes are aggregated into EUNIS classes based on detailed expert analysis, additional georeferenced data and relation between land cover classes and the EUNIS classification system. A crosswalk between EUNIS classes and CORINE land cover classes was already developed from the ETC-BD and will be used.
