跨平台地图缓存一体化的研究与应用

摘要

地图缓存技术是WebGIS中广泛采用的关键技术,然而不同平台的地图缓存应用给数据的生产和维护更新带来诸多不便.针对此问题,从地图缓存的生成算法出发,研究了跨平台地图缓存一体化的技术路线和实现方法,分别探讨了服务器端一体化和客户端一体化2种方式,旨在提高基础数据生成和应用服务的效率,为实现跨平台缓存一体化提供一种可行有效的解决办法.%The map cache technology is a widely-used key technology in WebGIS. However, much inconvenience has been brought to data production and maintenance by map cache of different platform. Arming at this problem, this paper described the basic algorithm, and discussed the technical route and realization method for cross-platform map cache integration. The server and client integration methods were discussed separately for improving the efficiency of data production and application. The results show that the method provided in this paper is a feasible and effective solution for cross-platform map cache integration.
