Abstract: Information processing and analysis are two important steps relating to finally acquired surface object recognition results in space imaging spectrometry.According to the flow of information processing,this Paper describes some key techniques,such as archiving processing,data compression, retrieval processing, radiometric and geometric correction etc.;and on the basis of remarking image restoration and enhancement processing and multispectral data information analysis methods, the techniques of artificial visual interpretation and computer analysis interpretation for imaging spectrum data are also studied and discussed.
