  1. Satellite ImageryandNature Conservation András Attila Takács – Tamás Lőrincz – András Révész (MoEW) 10. 06. 2006 – CEOS/WGCV-25 meeting

  2. Why does nature conservation uses satellite imagery? Extent of protected areas is diffuse

  3. Why does nature conservation uses satellite imagery? IR band: shows properties of habitats that cannot be seen on field • Structure of leafs • Photosynthetic activity • State of plants

  4. SPOT images Properties: • Green, red and 2 IR bands • 20 m multispectral and 10 m PAN resolution

  5. SPOT images

  6. SPOT images Until 2002 nature conservation used SPOT images: • Refine the boundaries of protected areas (2000) • Mapping of Ex lege areas • Background data for several vegetation mapping

  7. Landsat ETM Properties: • 7 bands (blue, red, green, NIR) • 30 m resolution

  8. Landsat ETM Usage: • Maping water influenced habitats, inundiation • Background image for IMS (ETM images of year 2000 (±3 years) are free)

  9. Other satellites IKONOS and Quickbird VIS and IR bands 4 and 2.4 m multispectral; 1 and 0.6 m PAN resolution Just on small areas

  10. What imagery Nature Conservation needs? To support protecting, assessing, monitoring and restoring natural and semi-natural habitats we need: • VIS and IR bands • Resolution of 5m to 1 m • Yearly recurrence Problem: • Licensing • BUDGET

  11. Thank you very muchfor your audience
