Multi band wavelet is a new branch of developing wavelet theory in recent years.This article focuses on the basic methods of multi band wavelet analysis and its merits compared with binary band wavelet. A technique for compressing and simplifying DEM with multi band wavelet is provided, and the experiment proves an ideal result.
