Cloud Computing, the Chances and Challenges for GIS

Based on the development of cloud computing, this paper analyzed the concept and technical framework of Cloud GIS, discussed the situation and problems of Cloud GIS development inland and abroad. Furthermore, this paper analyzed some advantages and basic work in large-volume spatial data management, high-performance geo-computing, geovisualization, geo-spatial information service platform construction in GIS development in China. Also, this paper discussed the challenges and difficulties in GIS popularization, cloud-computing infrastructure, Cloud GIS public service pattern and geodata capture and costs in Cloud GIS development of China. Finally, this paper concluded that Cloud GIS development will face the challenges and changes in geo-spatial data management, geo-computing, geo-information representation and terminal service, GIS thematic application system construction, GIS network application and service pattern in the future. These changes and challenges are the results of new technique development such as Cloud Computing, internet of things(IOT), conforming to the comprehensive and in-depth requirements of government, enterprise, society for GIS.
