The combination of geo-information and cloud computing: "GIS Cloud engine" in focus

At the end of April, "2012 University GIS Forum", GIS, cloud computing has undoubtedly become the most concerned topic. Because of the application characteristics of GIS, it is very suitable to adopt cloud computing model. In the future, cloud computing will greatly promote the development of GIS industry, will drive the GIS technology, Application Mode, deployment methods and other major changes.

With the introduction of the State Council's opinion on promoting the development of geographic information industry and the development of a series of planning of developing geo-information industry in the national basic surveying and mapping Twelve-Five, the geo-information industry will enter a high-speed development period. 2010 National Geographic Information Industry total output value reached 100 billion yuan, the national Surveying and Mapping Geographic Information Bureau concerned Personage said, "Twelve-Five" period, the geographical information industry will maintain the gross output value of 25% above average annual growth rate, to 2020 to form a trillion yuan of annual output.

At the same time, according to the reporter learned that the "China Cloud Science and technology development" Twelve-Five "special planning" has been approved by the State Council, will be released. The planning content includes the development idea, key task, technical route and support system of "China cloud" industry during "Twelve-Five" period.

According to Sadie Consultant research, China's cloud computing industry in 2011 the overall industrial scale, has exceeded 164 billion yuan, including infrastructure layer accounted for 40.6%, the application service layer accounted for 17%. 2012, China cloud computing market size will reach 60.678 billion yuan. "Twelve-Five" period, China's cloud computing industry chain size is expected to reach 750 billion-1 trillion yuan.

Undoubtedly, the combination of geo-information and cloud computing will provide a great opportunity for the development of industry. Liu, president of the China-Earth Digital Group, said earlier that he had told the Web reporter Cloud concept is actually a service-oriented concept, it is characterized by the service to the vast number of users, cloud-based GIS will enable the entire industry and services into a new stage of development, which will greatly expand its service population.

In recent years, some domestic GIS manufacturers in the geographical information and cloud computing technology integration, innovation and development has made its own practice. Among them, the digital on April 10 officially released the geo-spatial information sharing service platform solution Mapgis IGSS. The biggest feature of the new solution is to provide a highly efficient and reliable spatial Information Data Center (dcenter) and a rapidly configurable, cross-platform, extensible design and Development Framework (Designer) based on a large, virtualized hardware architecture (MicroCore). Center) provides a multi-level application service and solution to the "on-demand" model.

"With the development of computer technology, cloud computing has experienced a process from concentration to decentralization to centralization," said Professor Cheizong, executive director of the digital group in China. At the same time, geo-information technology has been developed. The traditional technology, such as geographic information data storage technology, geographic data technology and service technology, have corresponding technical defects in traditional GIS platform or traditional technology platform, which can not meet the requirement of spatial information computing in cloud computing era, which requires us to virtualize in storage.

He pointed out that cloud computing needs an engine that supports cloud computing with four features, scalability, functional and data separation, adaptive, functional services aggregation. With these four features in order to be able to call the cloud engine, the architecture can be calculated accordingly. The architecture of the physical information space is a computing center, the bottom of which is the infrastructure, which is transformed into a standardized virtual resource through a series of operations such as the physical resources through the corresponding cloud operating system to the virtualization of the cloud.

MapGIS IGSS's "GIS Cloud engine" strengthens the core function and deployment of GIS in current cloud environment, and lays the foundation for the realization of cloud GIS. At the same time, GIS cloud engine is also a digital research and development of the full Internet-oriented and cloud technology security kernel. MapGIS IGSS high reliability, high performance, scalable geo-information resources virtualization storage technology will provide customers with resources distributed, converged services, open cloud GIS services, is of great significance.
