  1. GLC2000 - Baltic Sea BasinMetria • 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,
