The Analysis of Landsat TM Digital Image Characteristics
陆地卫星TM仪器数字成像特点分析

The different characteristics between TM digital image and traditional passive senser image are discussed. It is point out that several present image models all approximately describe TM image procedure. By analysing LPE model, the conclusion that the high geometric accurcy of TM prodect can be achieved using this model which is only avaliable and reliable for TM image bulk processing in the present is given.
