This study introduces a component-based management platform for multi-source spatial data. The four-layer architecture and the main functions designed for the management platform are addressed in details. The main components, including the integration component for multi-source spatial data, the role-based security management component for spatial data, the user-friendly mapping component and the sharing component for spatial data are presented, respectively. Finally, as a typical application case, the platform has been used to manage the county-range agricultural spatial data in China.
