Measured:	Reflected solar radiation				Emitted thermal radiation		
Atmospheric influence:		In the blue & green range		Marginal			
Applications:			Mapping of biomass and vitality/ damage of vegetation
			Radar detection, meteoro-logical applications, land shifting	

1.	Use the following words to describe the different spectral areas of the electromagnetic spectrum and to complete the accompanying table: Near-IR – Detection of surface temperatures, soil moisture – Visible – Microwave – Reflected solar radiation – Mid-IR – Very high – Marginal – Ultraviolet – Detection of vegetation and soil moisture, geological applications, ocean currents – Visible Light – Marginal – Oil films on water, ozone concentration – Few – Microwave – Thermal-IR – Emitted thermal radiation – Near-IR – Reflected solar radiation – Detection of vegetation, water bodies and soils for land cover and land use mapping –Ultraviolet – Thermal-IR – Emitted & reflected radiation – Mid-IR.
