To reduce reflection of CPML undersurface,we employ vector absorbing boundary condition(ABC) as undersurface that can absorb scattering wave well under small disturbance of scattering field.

Conformal PML backed by vector absorbing boundary condition

Because change plots tone, which is detected automatically by dynamic monitoring of Land use, distributes in a definite range, in order to extract change information efficiently, change plot and its surroundings are bi-valued using technology of image processing of Photoshop, and vector boundary of change plot is drawn automaticaly by vector arithmetic of similar four directions in this paper.
