The role of remote sensing in Climate Change
Mitigation and Adaptation
SPOT 2001 NDVI SPOT 2001
Landsat Bands
Remote Sensing System Resolutions
• Spectral - Energy
• Spatial - Pixel size
• Temporal - Repeat time
• Radiometric
Cost vs Accuracy tradeoffSome areas will be more costly to monitor- clouds, hilly
terrain, other drivers of deforestation.Need for cost effective solutions
