The high resolution forest product consists of three types of (status) products and additional change products. The status products are available for the 2012 and 2015 reference years: 1. Tree cover density providing level of tree cover density in a range from 0-100%; 2. Dominant leaf type providing information on the dominant leaf type: broadleaved or coniferous; 3. A Forest type product. The forest type product allows to get as close as possible to the FAO forest definition. In its original (20m) resolution it consists of two products: 1) a dominant leaf type product that has a MMU of 0.5 ha, as well as a 10% tree cover density threshold applied, and 2) a support layer that maps, based on the dominant leaf type product, trees under agricultural use and in urban context (derived from CLC and high resolution imperviousness 2009 data). For the final 100m product trees under agricultural use and urban context from the support layer are removed. The high resolution forest change products…

Origine de la donnée :

The Forest Additional Support Layer (FADSL) provides information on trees under agricultural or urban use by utilization of CLC 2012 and HRL Imperviousness 2015. Considering different options for separating real “forest” areas as far as possible compliant with the FAO definition from non-forest tree-covered areas (i.e. trees predominantly used for agricultural practices, trees in an urban context) for the 20m Forest Type product, the following procedure is applied: In order to avoid misinterpretation of the 20m Forest Type product by potential users, specifically with respect to the contents / accuracies / information origins of the agreed additional information on "trees predominantly used for agricultural practices - broadleaved" (as derived from CLC classes 2.2.2 and 2.2.3) and "trees in urban context – broadleaved and coniferous" (as derived from a filtering approach applied to HR Imperviousness and from CLC class 1.4.1 Green Urban Areas), this additional information is made…
