Natura 2000 - 2012 (vector), Jul. 2019
Natura 2000 (an EU-wide network of nature protection areas established under the 1992 Habitats Directive) is the centrepiece of EU nature & biodiversity policy. The aim of the network is to assure the long-term survival of Europe's most valuable and threatened species and habitats.
A selection of Natura 2000 grassland-rich sites (5 grassland habitats types 6210, 6240, 6250, 6510 and 6520, including a 2km buffer and covering approx. 160.000 km2) sites was mapped in order to assess their actual area, their condition and their development over time. Land Cover/Land Use (LC/LU) classification was tailored to the needs of biodiversity monitoring in a buffer zone of selected Natura 2000 sites. LC/LU information is extracted from VHR satellite data and other available data in a buffer zone of selected N2K sites for supporting biodiversity monitoring and mapping and assessment of ecosystems and their services. The classes follow the pre-defined nomenclature on the basis of MAES typology of…
Origine de la donnée :
Generation of a LC/LU dataset using Very High Resolution (VHR) satellite data, with incorporation of existing Copernicus (High Resolution Layer, Local Components) and OpenStreetMap data. The Minimum Mapping Unit (MMU) is 0.5 ha. The positional accuracy is less than 5 m. Accuracy assessment approach: stratified random point sampling. Interpretation of sampling points has been performed on the best available reference data. The Overall Accuracy is higher than 85%. Minimum Mapping Unit (MMU): 0.5 ha Minimum Mapping Width (MMW): 10 m
