| Based on remote sensing data’s irreplaceable characteristics and superiority,it has been widely used inmapping,marine surveillance, environmental monitoring, seismic monitoring and other fields and can bringa variety of benefits,directly or indirectly.Therefore,different levels of the society more and more calls onremote sensing data sharing.In order to accelerate the pace of spatial information sharing, and activelypromote the development of spatial information industry,the Ministry of Science decided to build XXHeterogeneous Remote Sensing Systems(HRSS),implement space remote sensing data sharingpreliminary,and form a network structure covering many industries and organizations.The author isresponsible for the development of the service-oriented messaging middleware (HRWSMQ) module.HRWSMQ module is a core module of the XX Heterogeneous Remote Sensing Systems, its mainfunction is responsible for the vast majority of business processing in the system, including the integrationof heterogeneous systems, unified authentication, multipoint login and access control of multiple businesssystems users, as well as the communications between the various modules. In the development of thesystem implementation process, Middleware, WebService, unified data access interface are mainly used.The main work are:(1) fully understanding and analysis system business requirements, finish overalldesign of the HRWSMQ in HRSS;(2)according to the characteristics of cloud environment of the HRSS,achieve communication and data sharing between various cloud;(3) based single sign-ontechnology,propose a unified user authentication technology to realize users unified authentication ofmultiple system, multi-point sign-on and access control;(4)formulate unified integration specification,achieve seamless docking between heterogeneous systems;(5) according to the needs of the businessprocess of the system, provide unified access services data in the system through the unified data accessinterface. |
