Comparing satellite sensor results

This chart is a comparison of different mosaics of the same site in Siberia acquired using the 30-metre spatial resolution Landsat ETM+, the around ten times greater resolution MERIS and the 1-km resolution SPOT 5 VGT. What is clear is that MERIS delivers a level of detail closer to the former than the latter, making it a useful basis for the GLOBCOVER mapping project.
