GLC Baltic Sea Basin Metria Indata: SPOT VGT 10-day composites from to 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: Rasterdata for Norway, DCW vector data, 200m EuropeDEM. GLC 2000 – “FIRST RESULTS” WORKSHOP JRC – Ispra, March 2002

Area of Study

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)

Bad MIR Data

Water Pixel/ Cloud Problem

Speckled Composite Data

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

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,
