基于混合云模式的海洋基础地理信息云服务

GIS的表现形式已经由早期的系统转向了服务,而云计算已经成为支撑GIS服务的一种重要模式。面对广泛而迫切的海洋基础地理信息数据与应用需求,亟需构建一个统一的服务平台。结合云计算和GIS云服务发展现状,提出一个面向海洋基础地理信息、基于混合云模式、面向服务架构的海洋基础地理信息云服务体系架构设想,分析了需要重点研究的存储优化、自适应可视化与并行处理等关键问题,为构建"按需、实时、动态、易用"的服务平台提供了参考依据。

Towards Marine Fundamental Geographic Information Cloud Services Based on Hybrid Cloud

The form of GIS has shifted from an early system to a service,and cloud computing has become an important mode to support GIS services.Faced with broad and urgent requirements for the marine fundamental geographic information data and application analysis,it is very necessary to build an unified service platform.In this paper,the development status of cloud computing and GIS cloud services are analyzed first,then a system architecture vision of marine fundamental geographic information cloud service,based on hybrid cloud mode and service oriented architecture,is put forward.At last several key technologies,such as storage optimization,adaptive visualization and parallel processing,which needed to conquer are brought out.The advice in this paper would be beneficial to the service platform construction in a way of "on-demand,real-time,dynamic and userfriendly".
