Abstract:

As Web Geography Information System is getting complex, the data size increases tremendously and the client data requires faster access speed.To improve the efficiency of the clients on WebGIS,a new generation of map tile buffer solution is proposed and implemented. Finally,it is demonstrated by the practical application that,in use of the design of distributed cache tile data,the speed of the client browsing the map is improved and the performance of a large number of concurrent user accesses is enhanced.
