| 摘 要： | 针对传统WebGIS在多媒体数据存储与检索上存在的数据结构烦琐、检索效率低下等诸多问题,本文在阐述RIA技术的基础上,充分利用RIA客户端缓存机制,提出并实现了基于RIA的WebGIS多媒体数据的存储、检索以及离线操作模型。实验表明,该系统模型数据结构简明、清晰,检索效率较传统WebGIS有明显提高,同时也从很大程度上增强了客户端的用户体验感。

| Abstract: | In allusion to the problems of the storage and search of WebGIS multimedia data,such as complex data structure and inefficient search,the paper analyzed RIA,and then put forward and realized the storage and search and offline operation on WebGIS multimedia data based on RIA.As was shown by experiment,the data structure of the system model was brief and the efficiency of search was much higher than traditional WebGIS.At the same time,this system model strengthened the experiencing sense for the users. |
