Compared with traditional DEM or TIN based methods, this pure vector approach obtains not only the topological structure of drainage system in planar graph, but also the valley distribution polygon range. Depending on geometrical computation and judgment of vector line, polygon, the structured properties in drainage representation is enhanced, avoiding the case of noise disturbance in DEM based method. The core algorithm makes use of the ability of Delaunay triangulation in detecting hierarchical structure of each contour line.

In the third chapter, the problem of WCDMA network capacity has been introduced from the point of wireless planning. Through the analysis on WCDMA system load factor, the interference level allowance as well as the signal to noise ratio, the relation among WCDMA system capacity, coverage and the grade of service is demonstrated. The method to compute system parameters, such as traffic volume, system capacity, load factor, disturbance allowance and plot radius is also presented.
