I am working with some data of the metropolitan area of Manchester and just noticed that there were some very strange land conversions in the area from 2000 to 2006 recorded, when looking on the latest CORINE data (Version 15). A major urban area west of Manchester disappeared in CLC 2006, a big lake appeared north of it and agriculture changed quite a lot. However, when looking into the separate change file which can be downloaded from your database, these changes are not visible.
The figure shows the problem. I was wondering on which source the change file is based instead?
