Research on application of cloud computing techniques in WebGIS system

Cloud computing is a new method of shared infrastructure, it can provide supercomputing services. At the same time, WebGIS is the integration product of GIS and internet technologies, and it is inexorable trend with the development of GIS. The emergence of cloud computing brings new opportunities for WebGIS. This paper first introduced the principles of cloud computing and WebGIS, and then introduced cloud computing techniques in WebGIS applications, which included data storage, spatial analysis and GIS web services. Finally, several issues about cloud security, privacy, regulations standard and long-term viability are proposed in WebGIS applications based on cloud computing.
