Application of big data storage technology in surveying and mapping data management

Ping Zongwei  
[Abstract]: Based on the construction of geographic information spatiotemporal big data center in Shandong Province, facing the massive spatial-temporal big data storage demand, after analyzing the characteristics of geographic information resource management and application, this paper proposes a big data storage technology based on Cloud Architecture. Through the horizontal division of the application level of the database, and using the distributed storage technology, the distributed matrix is created, which solves the problems of low data browsing efficiency, poor concurrency performance and small scalability in the massive mapping data storage, and provides the underlying technical support for the storage and application of mapping geographic information big data.
