1 GLC2000 - Baltic Sea Basin Metria Indata: SPOT VGT 10-day composites from 01- 04-2000 to 21-10-2000 and several SPOT VGT S- 1 composite data for June and September. Channels: 2 visible (blue/red), NIR, MIR, NDVI, Status Map, Viewing Zenith Angle. Ancillary Data: CORINE LC, BALANS LC/LU, Sverigeklassning data, 1:250 000 Rasterdata for Norway, DCW vector data, 200m EuropeDEM. GLC 2000 – “FIRST RESULTS” WORKSHOP JRC – Ispra, 18-22 March 2002

2 Area of Study

3 Pre-processing of Indata Remove bad MIR data Remove water ”ring” around coast Remove pixels with a VZA > 50º Remove clouds Remove snow Remove urban areas (based on ancillary data)

4 Bad MIR Data

5 Water Pixel/ Cloud Problem

6 Speckled Composite Data

7 Processing Unsupervised classification (40 classes) Majority clustering Masking of clusters which correspond exactly to reference data Second unsupervised classification (40 classes) Automatic and manual comparison od clusters with reference data Labelling of clusters

8 Results 22 Classes in final legend 11 pure and 11 mixed classes Countries include: Denmark, Estonia, Finland, Germany, Latvia, Lithuania, Norway, Poland, Sweden. Additional coverage: Austria, Belarus, Belgium, Czech, France, Hungary, Luxembourg, Moldova, Netherlands, Rumania, Russia, Slovakia, Switzerland,
