Landsat Bands
5
Power in Satellite Data Complete spatial coverage of surface Consistent manner Updated regularly Cost effective Increasingly high spatial resolution Captures spectral energy beyond Visible Light
6
Remote Sensing System Resolutions Spectral - Energy Spatial - Pixel size Temporal - Repeat time Radiometric Cost vs Accuracy tradeoff Some areas will be more costly to monitor- clouds, hilly terrain, other drivers of deforestation. Need for cost effective solutions

Remote Sensing plays a key role in climate change research –combined with ground measurements Extrapolation of plot measurements to the regional or national level
