The research work and innovation of this paper are as follows: (1) This paper proposes a seamless and unified access method for heterogeneous cloud storage services based on file system Wukong. At present, different cloud storage service access interfaces vary, because of the lack of seamless access to a variety of cloud storage Services Unified interface, spatio-temporal data applications can not modify the direct access and use of the back-end cloud storage data. File system is a kind of data use interface which is widely supported by applications, and the file system interface encapsulates various cloud storage services to ensure direct access to heterogeneous cloud storage services. This paper first proposes a seamless and unified access method for heterogeneous cloud storage services based on file system Wukong file system. Wukong through the Heterogeneous Service Interface Abstraction Encapsulation technology, realizes the consistent management to many kinds of cloud storage service, guarantees the Spatiotemporal data application to the heterogeneous cloud storage Service Unified access. Wukong through the interface encapsulation technology based on bridging mode, the transformation of cloud storage Access interface to file system interface is realized, which ensures the transparent access of spatiotemporal data application to cloud storage service. For mobile environment, this paper reduces the requirement of network environment by adaptive compression and off-line service camouflage, and ensures the effective access of mobile devices to cloud storage service under different environment. (2) A Easync file synchronization mechanism is proposed to support multiple data views. Because of the increasing popularity of personal digital devices, people often have multiple devices. In the application of spatio-temporal data and data collection, the data between the devices can be used to assist each other, for example, the equipment can use the collected GPS data to modify the map data, and the map data can be used to further improve the accuracy of the GPS data collected. Therefore, the transparent synchronization of data between multiple devices is beneficial to provide better support and protection for spatio-temporal data application.
