Based on analyzing the characteristics of spatial data in combination with current spatial data storage technology, this study implements the organization and management of multi-source spatial data and builds the Multi-source Spatial Data Management System. For implementing the system, this study solves the problems of spatial data thematic diversity and data exchange by extending the metadata standards, solves the issues like large amounts of data, distributed source and heterogeneous data format using single machine multiple SDE data storage technology, and finally, in order to solve the problem of fast retrieval localization of spatial data, systematically builds the spatial index database based on single machine multiple SDE. The system lays a good foundation for solving thematic diversity, data sharing and exchange which will be met in the information platform construction of multi-source spatial data for the applications of resource and environmental remote sensing data.
