Abstract
This document reports the production of three maps for Continental Portugal: CORINE
Land Cover Changes 2000-2006 (CHA06_PT), CORINE Land Cover 2006 (CLC06_PT), and
a revised version of the CORINE Land Cover 2000 (CLC00_PT). These maps were produced
by the Remote Sensing Unit of the Portuguese Geographic Institute, within the Global
Monitoring for Environment and Security Land Fast Track Service Precursor (GMES Land
FTSP) for Continental Portugal. GMES Land FTSP is an initiative created by the European
Environment Agency (EEA) and European Commission (EC), namely with the goal of
updating previous CORINE Land Cover (CLC) mapping initiatives.
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 land use and land
cover (LULC) types in the territory and the main source of change dynamics.
