Info

Considering the third and most detailed level in the CLC nomenclature (Table 16) it can be seen that the classes that occupy a larger portion of the Portuguese Continental territory in 2006 are 324 (Transitional woodland-shrub), 311 (Broad-leaved forest) and 211 (Non- irrigated arable land). The same happens for the CLC00_PT map, reinforcing the importance of the forest and agricultural sectors in Continental Portugal. Within Artificial surfaces, class 112 (Discontinuous urban fabric) is the most abundant, while for Wetlands and Water bodies, classes 421 (Salt marshes) and 512 (Water bodies) are respectively the dominant ones. Finally, it is important to mention that when comparing CLC00_PT and CLC06_PT, the percentages of change per class are not exactly the same as the ones that result from CHA06_PT. This is due to the generalisation procedures applied and also to the fact that the products have different minimum mapping units: whereas CHA06_PT has a MMU of 5 ha, both CLC00_PT and CLC06_PT have a MMU of 25 ha.

4 Conclusions Conclusions Conclusions This report described the production procedures and general results of the CORINE Land Cover 2006 for Continental Portugal. The National Technical team coordinated the production process of the project, carried out during 2008 and 2009 at the premises of the Portuguese Geographic Institute. The production process included visual interpretation of satellite imagery to detect land use and land cover changes in the period from 2000 to 2006, in Continental Portugal, and integration of the resultant product with the CLC00_PT database to create the CLC06_PT map. This process was accompanied by permanent quality control breakpoints to ensure demanded quality standards. A validation protocol was applied to the CLC06_PT map and the estimated overall accuracy was 90,2%, with an absolute precision of 1,3 at the 95% confidence level. The results obtained also show that 7,8% of the original CLC2000-PT database was corrected when producing CLC00_PT, and that 8,6% of the area of Continental Portugal was affected by land use and land cover changes, in the period from 2000 to 2006. Forest and semi- natural areas, as well as Agricultural areas, continue to be the dominant LULC types in the territory and the main source of change dynamics.
