A GA-based Band Selection Algorithm for Hyper-spectral Image Classification

Abstract

We studied on the relationship between oceanic variation in the offshore and abnormal sea surface temperature rise in the coastal area of the Yellow Sea using a variety of satellite and in-situ data during winter 2004. In results of the satellite data, the average value of sea surface temperature in the Yellow Sea for 2003 was , and the average value of sea surface temperature for 2004 was . It was higher than those of the last year about . In results of the in-situ data, the average value of surface layer temperature in the Yellow Sea for 2003 was , and the average value of surface layer temperature for 2004 was . In the same satellite data, it was higher than those of the last year about . In results of the T-S diagram, we divided definitely into water mass of the Yellow Sea and the East China Sea in 2003. But we didn't divide definitely into water mass of the Yellow Sea and the East China Sea in 2004. The average values of air temperature and wind speed for 2003 were and 4.81 m/s, respectively. And, the average values of air temperature and wind speed for 2004 were and 4.52 m/s, respectively. So, These were similar. But the wind directions for 2003 were superior northwestern wind, and the wind directions for 2004 were various northern wind. The wind directions were different from each other. Therefore, the abnormal sea surface temperature rise in the coastal area of the Yellow Sea during winter 2004 were better related to oceanic variation in the offshore than influences of atmosphere. In the future, We will do in-depth study for these.
