Space Data Needs.Based on actual available sensors.
• Semi-annual early warning System. Coarse resolution datasets– SAR. Best L band sensors or C/X band. Wide Beam modes.
– Optical. Coarse resolutions, MODIS/LISS sensors.
• Annual wall-to-wall. Medium resolutions datasets.– Landsat 8. Dedicated connection for the whole catalog. Pixel
by pixel co-registered.
– SAR. Best L band sensors or C/X band. Fine Beam modes.
At least for the Pacific region whole coverage. SDCG-4, Caltech, CA, USA4th-6th September 2013
• Annual wall-to-wall. Medium resolutions datasets.
– Other medium resolutions catalogues (SPOT 5, LISS III/IV, next CBERS.
– Validation based on stratified sample of High resolution images (i.e. spot 5/6, RapidEye, QB, Ikonos, Formosat).
• DEM. National cover at the major resolution for pre- processing steps of Optical/SAR catalogues (SRTM, SRTM-ASTER, TanDEM).
Space Data Needs.Based on actual available sensors.
SDCG-4, Caltech, CA, USA4th-6th September 2013
• Plans:– SAR Interferometric catalogues for precision change cover
analysis. Actually this information is not available for the country.– SAR/Optical complete time series to assure time consistency
(deforestation and degradation ).
Current challenges & obstacles.– Operational pre-processing SAR algorithms.
– Cloud computing.
– Degradation analysis.

Current challenges & obstacles.– Availability of RS to implement operational phase of
MGD
– Availability of Operational pre-processing SAR algorithms.
– Availability of funding to do a “joint work” with SDCG-MGD
– Data infrastructure / Cloud computing
(Datacube? FAO-SDMS?, SDMS?).
