5). Estimation of chlorohpyll concentration in the sea water 
217 
In our studies, the PC vector 2 image from MAIS band 1 to 15 (44 0-74Onm) has been used as a 
indicator of chlorophyll concentration. After processing by exponential stretch and density 
slice, the relative distribution map of pigment chlorophyll concentration was obtained(Fig 4-6). 
The flow diagram of processing is as follows:

6). Analysis of theraml infrared multispectral images of MAIS. 
According to the characteristics of airborne images, some special image processing such as 
targent distortion correction, boundary radiance correction and the atmospheric correction are 
also emplaed. On the base of pre-processing the temporature image conversion, emittance 
image conversion are made before analysis and information extraction, for anlysis of the earth
