Abstract: With the completion of the smart city space-time big data platform, relying on its time traceability, spatial comprehensiveness, and diversity of data types, there is a large space for upgrading and transformation of the natural resources archives management system. In this paper, through the construction of the smart city big data platform in four aspects: spatiotemporal information big data, spatiotemporal information cloud platform, supporting environment, and smart application demonstration. Through the analysis of capacity, this paper studies how to upgrade the file data sorting and storage function in the natural resources archives management system, and transforms the system function modules, so as to realize the integrated management of the map, number and file of the natural resources archives, and meet the management and use needs of the natural resources departments.
