1. Satellite Imagery and Nature 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. Until 2002 nature conservation used SPOT images: 1. 1. Refine the boundaries of protected areas (2000) 2. 2. Mapping of Ex lege areas 3. 3. Background data for several vegetation mapping

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

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

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

10. 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 What imagery Nature Conservation needs?

11. Thank you very much for your audience
