Research On GIS Application Model Based On Cloud Computing

Cloud Computing is one of the hit technologies that developed in computing industry in recent years. It turns all IT resources into a service that customers can rent based on their practical need and teamwork through internet. Cloud computing has a potentially vast developing market and many IT technology companies have built their own platform for cloud computing.As a geographical data collecting, storing, managing, and analyzing computing system, GIS has been integrated into the main stream of IT technology. In GIS industry, it is necessary to adopt cloud computing technology to form geological data system in order to simplify the application and management of GIS and to reduce the investment and operation cost at the same time to promote the flexibility of GIS applications and its infrastructure.This paper will adopt the cloud computing into geographic information system and study the application of cloud computing in GIS industry. It will analyze the performance of software and its service, platform and its service, infrastructure and its service provided by cloud computing in GIS. It will also try to research the key technology needed in forming cloud computing GIS, and explain how GIS can effectively work with the existing cloud computing platforms, analyze how to transfer GIS service to cloud computing and point out the safety problems in that transformation. In the end, this paper will also explore how to use ArcGIS server to transfer geographic information service into cloud computing and how to integrate Google and the common cloud computing.This paper tries to explore how to employ cloud computing into the GIS industry. The application of cloud computing in GIS is demonstrated in the following two aspects: first, use cloud computing technology to reform and upgrade the GIS technology in order to provide all GIS services in cloud computing and enable the online GIS have all the functions of desktop GIS, and to package all the functions of GIS software so that to realize their online sales; Second, integrate GIS software with commercial cloud computing to store GIS data into cloud computing platform so that all GIS functions will be optimized with the support of commercial cloud computing.The creative points of this paper are as followed: First, it tries to discuss in depth the concept, category, consistent of GIS and its development in cloud computing mode. This paper analyzes the connotation of cloud computing and key technologies in forming cloud computing, it also analyzes the existing types of existing platform for commercial cloud computing and the technologies it employs and its services.Second, this paper points out the four forming modes of cloud computing in GIS by combining the service modes cloud computing provides. The four modes are geographic information and its service, geographic information software and its service, geographic information platform and its service, and geographic information infrastructure and its service. This paper also provides the original system of geographic information software and its service.Third, this paper explores how to effectively integrate the existing cloud computing platform with GIS system software and how to transfer the all the functions of GIS into commercial cloud computing by considering the cloud computing plan of ESRI.Four, this paper explores how to integrate private and public cloud computing by trying to build the wheat inquiry system in Henan province. It tries to prove the concept of geographic information platform and its service and provides API as a service.
