description Lifting scheme is a new wavelet transformation method, which is more effective than the multi-resolution analysis of wavelet theory. This paper presents the fundamentals and the three constructing steps of lifting scheme briefly. And it uses lifting method to process DEM data with multi-scale representation. It introduces structure algorithm briefly and emphasizes the improved structure algorithm in detail; finally it shows the experimental method and process of extracting the characteristic line of terrain from the multi-scale DEM data by using the improved structure algorithm.
