Multi-source data management in soil erosion monitoring system at regional scale

With the assistance of GIS and RS technology, it is extremely crucial to manage the huge volume, multisource and multiscale spatial data for the design and development of geographic information system. The database and its client management system have been developed to act as a data management and integrating platform in the soil and water loss monitoring system in the upper basin of Miyun reservoir. This work expounded the detail about the design technique and framework of the database in practice, and focused on manipulating the huge volume spatial data management, which was based on the software of Oracle9i and ArcSDE version 8.2 and the support of object-oriented technology. The paper approached to put forward a feasible and practical technology project reference for the construction of the applied GIS on the aspect of system database construction, and especially for which needs to manage both spatial data and nonspatial data.
