1. Which Landsat platforms have the Multispectral Scanner(MSS), which have the Thematic Mapper(TM), and which have the Enhanced Thematic Mapper Plus(ETM+)?
1.Study the differences between the MSS and TM bands. How are the TM bands an improvement over the MSS bands? Why do the TM bands offer improved vegetation discrimination over those of the MSS? How does Landsat 7 offer more in mapping capabilities?
1.Using the TM bands, how could one distinguish between clouds and snow?
1.For each of the following, choose one or more TM bands and explain why you think it should be used for the following feature discrimination:
Vegetation Moisture Content?
Soil Moisture Content?
Water Body Penetration?
Mineral and Rock Types?
