Satellite Imagery and Nature Conservation András Attila Takács – Tamás Lőrincz – András Révész (MoEW) – CEOS/WGCV-25 meeting
Why does nature conservation uses satellite imagery? Extent of protected areas is diffuse
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
SPOT images Properties: Green, red and 2 IR bands 20 m multispectral and 10 m PAN resolution
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
Landsat ETM Properties: 7 bands (blue, red, green, NIR) 30 m resolution
Usage: Maping water influenced habitats, inundiation Background image for IMS (ETM images of year 2000 (±3 years) are free) Landsat ETM
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
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?
Thank you very much for your audience
