In recent years, many natural disasters have occurred because ofabnormal climate. In a time like this, use of satellite data isadvantageous to observation of the disaster region for a wide area.However, in order that photo sensor data may tend to be subject to theinfluence of atmospheric, synthetic opening data attracts attention.And, this research examined coherence data among the informationgenerated from the Synthetic Aperture Radar data. The results of theresearch are as follows: 1)The coherence value of a vegetation region islow. This result is expressing that the growth environment of vegetationdiffers for every year. 2)The coherence value of a city area is high.
