Good Afternoon, I have intersected the CLC inventories for 1990, 2000 and 2006 with LUZ' boundaries (2009) for the city of Barcelona (LUZ code: ES002L). However, CLC code 124 (airports) is missing in year 2000; examination of the maps obtained in ArcGIS (see attachment) shows that the polygon has been omitted. Why is it so? I'll be waiting for your kind comments. KR, sofia p.
