%X To meet the demands of Multi-Radius Buffer Analysis and Road Intersection & Position, which are key issues in Spatial Decision Support System for Controlling the Outbreak and Spread of Animal Epidemics(SDSSCOSAE), two solution were suggested respectively: Using HashMap structure to store the results after multi-buffering processed, a set-difference operation among these results helped to obtain different area datasets we needed. In a view of visualization, a method of using cyclic regular polygon to simulate circle was adopted to separate different multi-radius buffering areas. Specially, an algorithm of Road Intersection and position was discussed. Both solutions were independent of special WebGIS platform. The practical application shows that such solutions mentioned above can be commonly used. Also the design and implementation of SDSSCOSAE were briefly introduced in this paper.
