空间信息云服务聚合平台架构设计与实现

Design and Realization of Composition Platform Framework of Space Information Cloud Services

GIS云服务和GIS服务聚合都是当前GIS应用领域的研究热点。本文通过分析国内外空间信息服务的聚合研究状况和空间信息服务在云平台上的发展趋势,设计了一种基于云计算的、面向服务群的GIS服务聚合平台软件框架。通过参考现有服务质量模型,结合云计算在服务质量评价方面的影响,设计了聚合服务质量评价模型。该模型针对云计算的健壮性、高可用性和弹性伸缩等特点,实现了对空间信息云服务质量的动态记录和评价。该软件框架聚合了百度地图、天地图、Arc GIS等多种主流空间的信息服务,并且聚合阿里云、百度云和私有Open Stack云平台,具有一定的实用性。

GIS cloud services and GIS service composition are research hotspot in the current GIS application field. In this paper, through analyzing the research status of the space information service at home and abroad and the development trend of the space information service on the cloud platform, the authors designed a software framework of GIS service composition platform based on cloud computing and service-oriented group. Through referring to the existing service quality model and combining impact of cloud computing on service quality evaluation, the authors designed quality evaluation model of service composition. With features of robustness, high availability and elasticity, the model was realized the dynamic recording and evaluation to service quality of space information unit. The software framework was aggregated information services of mainstream spaces such as Map world, Baidu Map and Arc GIS as well as Alibaba Cloud, Baidu Cloud and Private Open Stack Cloud Platform, which has certain practicality.
