  3. Masking Procedure • Pixels polluted with clouds, cloud shadow, or defective SWIR sensor effect, and pixels located beyond the critical view zenith angle for maintaining spatial resolution were discarded

  4. Data Used Mosaic of Dry Season (Jan-Feb, 2000) 2R, 1G, 4R

  5. Supervised Classification Unsupervised Classification

  6. Land use/land cover maps Forest cover maps Landsat/SPOT data

  7. Land Cover Labels-LCCS • Broadleaved Evergreen Forest • Broadleaved Deciduous Forest • Needleleaved Evergreen Forest • Needleleaved Deciduous Forest • Semi-deciduous Forest (Mixed Forest) • Broadleaved Evergreen • Flooded Forest • Mangrove Forest • Wooded Land (inundated) • Shrubland • Herbaceous (Grassland) • Barren or Sparsely Vegetated • Croplands • Snow and Ice • Waterbodies

  8. Grassland SPOT VEGETATION LANDSAT 7

  9. Evergreen and Deciduous is Difficult Evergreen Forest Landsat 7 Data Deciduous Forest

  10. On-going Activities • Use summer season data • Refine classification results • Use other classification approaches • Decision Tree Classifier • Expert Image Classifier • Acquisition of Landsat 7 ETM+
