2 vs. CLC 1 Occupation Biophysique du Sol is an inventory of land cover and biotopes in the Grand Duchy of Luxembourg at the scale of 1:1.. The inventory is a classification of 76 different land cover and biotope types with five hierarchical levels. This database has been updated as part of the GSE Land extension for Luxembourg. 1.1 Nomenclature The five main hierarchical levels of the nomenclature are: 1. Artificial surfaces Artificial surfaces encompass 29 specific classes. At level 3 the nomenclature encompasses built-up areas for residential or industrial use as well as commercial areas transport infrastructure construction areas and areas used for mineral extraction or deposition of waste materials or green areas in an urban context (e.g. parks cemeteries sport and leisure areas). Each of these level 3 classes is further differentiated into individual classes with distinct uses or functions. 2. Agricultural areas This level includes 8 different kinds of surfaces used for agricultural production. The main use of the surface is to be mapped i.e. seasonal differences (e.g. harvested croplands) or materials temporarily stocked on the land are not mapped. 3. Forests and semi-natural areas Compared to Corine Land Cover this level has undergone a strong restructuration and the inclusion of additional interpretation parameters going beyond the information provided in the image alone. The level is subdivided into two main groups of classes: 14 forest classes mainly differentiated by its leaf type and another 13 classes describing different types of semi-natural lands (grasslands shrublands open areas). Common base for the semi-natural lands is little human impact on them. 4. Wetlands The nomenclature differentiates 3 types of wetlands which are mainly defined by the vegetation type found. 5. Water Water classes (9) are first differentiated into running water or still water bodies. Subsequently both are further subdivided into natural or artificial origin respectively with or without biological interest. 1.2 List of classes The land cover and biotope features are divided into 76 classes with areal extend (polygon data). Landscape elements (small water bodies hedges isolated trees tree rows or groups of trees) below the official minimum mapping unit are mapped as point and line elements. Overall 2 point and line features are differentiated leading to a total of almost 1 different types of land cover and biotope types in form of point line and polygon data. GEOVILLE 2/2

7 vs. CLC 3 COMPARISON OF CLC AND Both classifications were imported to ArcGIS and intersected to obtain the classes which are part of the large CLC polygons / classes. Figure 1 left: right: CLC-Luxembourg Table 1 shows a comparison of the surface (in km 2 ) and number of polygons per land cover class in 27 and CLC26. Please note that most classes description of and CLC are similar at level 3 of the nomenclature, but for some classes signification differences exist: classes x & x: The definition of class x in is different from CLC. does not contain any forestry surfaces without trees (clear cuts, storm damages, regrowth) in this class. These surfaces are mapped as (regrowth) and (clear cuts, storm damages. class x This class describes pioneer vegetation areas while in CLC this class is used for Mediterranean-type vegetation. Also, does not contain any heterogeneous classes (classes 2.4.x in CLC). GEOVILLE 7/2

9 vs. CLC 4 FINAL STATISTIC: VS. CLC The Intersect attribute table was exported to Excel and a Pivot Table was produced. In order to assess the composition of each CLC class with respect to the higher resolution national land cover database, the percentage of each class for every CLC class was calculated.
