Corine Land Cover (CLC) 2018 and CLC change 2012-2018 are two of the datasets produced within the frame of the Initial Operations of the Copernicus programme (the European Earth monitoring programme previously known as GMES) on land monitoring.Corine Land Cover (CLC) provides consistent information on land cover and land cover changes across Europe. This inventory was initiated in 1985 (reference year 1990) and established a time series of land cover information with updates in 2000, 2006. 2012 and now 2018. CLC products are based on photointerpretation of satellite images by national teams of participating countries - the EEA member and cooperating countries – following a standard methodology and nomenclature with the following base parameters: 44 classes in the hierarchical three 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 the change layers is 5 hectares. The resulting national land cover inventories are further integrated into a seamless land cover map of Europe. Land cover and land use (LCLU) information is important not only for land change research, but also more broadly for the monitoring of environmental change, policy support, the creation of environmental indicators and reporting. CLC datasets provide important datasets supporting the implementation of key priority areas of the Environment Action Programmes of the European Union as protecting ecosystems, halting the loss of biological diversity, tracking the impacts of climate change, assessing development in agriculture and implementing the EU Water Framework Directive, among others.

Riparian zones represent transitional areas occurring between land and freshwater ecosystems, characterised by distinctive hydrology, soil and biotic conditions and strongly influenced by the stream water. They provide a wide range of riparian functions (e.g. chemical filtration, flood control, bank stabilization, aquatic life and riparian wildlife support, etc.) and ecosystem services. The Riparian Zones products will support the objectives of several European legal acts and policy initiatives, such as the EU Biodiversity Strategy to 2020, the Habitats and Birds Directives and the Water Framework Directive. Land Cover/Land Use (LC/LU) classification is tailored to the needs of biodiversity monitoring in a tailored buffer zone along large and medium-sized European rivers (with Strahler levels 3-8 derived from EU-Hydro). LC/LU is extracted from VHR satellite data and other available data in a buffer zone of selected rivers. The classes follow the pre-defined nomenclature on the basis of MAES typology of ecosystems (Level 1 to Level 4) and Corine Land Cover, providing 80 distinct thematic classes with a Minimum Mapping Unit (MMU) of 0.5 ha and a Minimum Mapping Width (MMW) of 10 m. The production of the Riparian Zones products was coordinated by the European Environment Agency in the frame of the EU Copernicus programme.
The main high resolution grassland product is the Grassland layer, a grassland/non-grassland mask for the EEA39 area. This grassy and non-woody vegetation baseline product includes all kinds of grasslands: managed grassland, semi-natural grassland and natural grassy vegetation. It is a binary status layer mapping grassland and all non-grassland areas in 20m and (aggregated) 100m pixel size. Two additional (expert) products complete the high resolution grassland product: the Ploughing Indicator (PLOUGH) and the Grassland Vegetation Probability Index (GRAVPI). While the PLOUGH concentrates on historic land cover features with the aim to indicate ploughing activities in preceding years, the GRAVPI provides a measure of classification reliability. GRAVPI is a 20m pixel size product, mapping on a range of 1-100 the class probability. PLOUGH is a 20m pixel size additional product, mapping from 1-6 the number of years since the last indication of ploughing. A verification of the Grassland layer was performed by the National Land Survey of Iceland during autumn of 2018 and the data and resulting report are made available on the NLSI websites.
