Description: CLC90 is one of the datasets produced within the frame the Corine Land Cover programme referring to land cover / land use status of year 1990.
The Corine Land Cover (CLC) is an European programme, coordinated by the European Environment Agency (EEA), providing consistent information on land cover and land cover changes across Europe. CLC products are based on the photointerpretation of satellite images by the national teams of the participating countries - the EEA member or cooperating countries. The resulting national land cover inventories are further integrated into a seamless land cover map of Europe. The resulting European database is based on standard methodology and nomenclature with following base parameters:
- 44 classes in the hierarchical 3-level Corine nomenclature
- minimum mapping unit (MMU) for status layers is 25 hectares
- minimum width of linear elements is 100 metres
- minimum mapping unit (MMU) for Land Cover Changes (LCC) for change layers is 5 hectares
CLC programme provides important data sets supporting the implementation of key priority areas of the Environment Action Programmes of the European Community as protecting ecosystems, halting the loss of biological diversity, tracking the impacts of climate change, assessing developments in agriculture and implementing the EU Water Framework Directive etc.. CLC programme is also a part of the Global Monitoring for Environment and Security (GMES http://gmes.info) initiative, run by the European Commission and the European Space Agency, which will provide environmental information from a combination of air- and space-based observation systems and in-situ monitoring.
