摘要

随着无线通信、移动计算和位置定位技术的快速发展,基于位置的服务(LBS)正在成为最有前途的应用之一。现在,地理标记语言(GML)正在成为因特网上表示和交换地理信息(包括地理特征的空间和非空间属性)的事实上的标准。GML为地理空间对象的定义提供了一个开放的、与供应商无关的框架,这使得使用GML在LBS中集成各种空间数据源具有更强的互操作性。本文讨论了利用GML增强基于web服务的LBS性能时的服务发现和空间操作问题。体系结构包括后端数据库服务器、本地空间信息服务器、全局空间信息服务器和J2ME客户端;服务器采用双tie架构,包括全局空间信息服务和局部空间信息服务;客户端是在各种移动终端上访问远程空间信息服务,并显示LBS服务信息的内容。样机验证了该方法的可行性和有效性。

Towards Spatial Information Services in LBS: A GML-Based Approach
Location based service (LBS) is becoming one of the most promising application with the rapid development of wireless communication, mobile computing, and location positioning technologies. Now Geography Markup Language (GML) is emerging as the de facto standard in representing and exchanging geographic information that includes both the spatial and non-spatial properties of geographic features over the Internet. GML provides an open, vendor-neutral framework for the definition of geospatial objects, which makes it much more interoperable to use GML to integrate various sources of spatial data in LBS. This paper discusses the service discovery and spatial operation issues when using GML to enhance the performance of LBS based on web service. The architecture includes back-end database server, local spatial information server, global spatial information server, and J2ME client; the server adopts two-tie architecture, which includes global spatial information service and local spatial information service; the client is to access the remote spatial information service in all kinds of mobile terminals, and displays the contents of LBS services information. The prototype shows that this approach is feasible and efficient.
