Buffer analysis is one of the most important spatial analysis method in GIS.Based on the fact that existing algorithm is lack of efficiency,this paper presents a random algorithm for buffer generation which can realize parallelization and be implemented easily.It designs several applied modes for SVG visualization to adapt the universality application of buffer analysis,uses Sherwood random algorithm for optimizing computation efficiency and solves the visualization problem by using the mask object of SVG.Testing results prove that this algorithm can increase the efficiency while dealing with large dataset.
