Through the selected sample analysis, before the earthquake by MNF ALOS image transform the image, in its first 2 band, for building with bare soil will have a better separation, when building a tree, and can be used to differentiate between the two.

Through sample analysis which selects front, shakes image ALOS the image which obtains after the MNF transformation, in its second wave band, yongde has the good separation property regarding the construction with the bare earth, therefore in construction decision tree time, may use for to different

Through the selection of samples for analysis before earthquake images ALOS by MNF resulting from the transformation of the image, in its second wave, for isolation of building land with bare soil better, so when you build a decision tree, can be used to distinguish between the two distributions.
