摘要
在分析常用的WebGIS空间数据缓存技术的基础之上,提出了一种WebGIS空间数据分布式缓存体系,并通过一个实例对分布式缓存系统的性能进行了分析。
According to the characteristics of WebGIS and spatial data, a distributed cache system is proposed in this paper. Some key problems needed to be resolved in the implementation of distributed cache system including cache spatial data selecting, distributed cache building, distributed cache management and cache consistency maintaining are discussed. Finally, the performance of this distributed cache system is analyzed with a case study.
