摘要
为实现高速铁路资产统一管理,建设高速铁路地理信息系统十分必要。由于现有的GIS服务无法满足高速铁路专业复杂逻辑的需求,因而研究使用GIS服务聚合技术、GIS服务对象扩展技术来聚合和扩展GIS服务,并阐述GIS服务聚合的2种方式和GIS服务对象扩展的流程。在此基础上,通过使用Oauth 2.0授权协议实现对GIS服务访问的权限控制,进而丰富扩展高速铁路专业GIS服务,为系统中专业、复杂的GIS功能的实现提供服务保证。最后,以京沪高速铁路为例展示GIS服务聚合和扩展技术的应用。
In order to realize the unified management of high-speed railway assets, it is necessary to establish the high-speed railway geographic information system. Because of current GIS service not satisfying the demand of complex business logic of high-speed railway, GIS service aggregation technology and GIS severice object extending （SOE） technology are applied on aggregating and extending GIS service. This paper expounds 2 ways of GIS service aggregation and the process of GIS SOE. Based on above, the authority control of GIS service access is realized through Oauth2.0 authorized agreement, and then special GIS service of high-speed railway is extended, providing service guarantees for realization of technical and complex GIS functions in the system. In the end, taking Beijing-Shanghai high-speed railway as an example, the application of GIS service aggregation and GIS SOE technologies are shown in the paper.
