| 摘 要： | GIS的空间数据传输技术正在经历从有线到无线的发展过程。针对目前无线网络环境下存在的网络带宽不高、频繁断接、资源有限等不足带来的空间信息传输效率降低的问题，本文论述了一种新型无线网络环境下空间信息数据传输的方法。根据无线GIS技术特点，通过分析自适应理论和无线传输特征模型，探讨空间信息自适应传输的访问方式，设计基于无线网络的自适应空间数据传输策略，并通过具体试验验证了该策略的可行性和有效性。 |

| Abstract: | The technology of GIS spatial data transferring and storage is experiencing the development from wired network to wireless networking at present.In allusion to the deficiency of low bandwidth,frequent disconnection and finite resource under the wireless condition,this paper introduces the method of transferring the interspaced data and information in new wireless environment Based on the GIS self-adaptation transfer strategy,and analyzes self-adaptation transfer characters,optimization principle which preserves the desired spatial update efficiency has been designed..the proposed mechanism has been proved to be feasible and efficient by the scrupulous examination results. |
| Keywords: | wireless network GIS spatial data self-adaptation transfer |
