Data Management in Soil Erosion Monitoring System Using Spatial Database and Its Multi-level Updation

With the assistance of GIS and RS technology, it is extremely crucial to manage the huge volume, multi-source and multi-scale spatial data for the design and development of data management, which was based on the software of Oracle9i and Arc SDE version 8.2and the support of object oriented technology. The paper approaches to put forward a feasible and practical technology project reference for the construction of the applied GIS on the aspect of system database construction, to provide multi-level updation of eroded land and especially for which needs to manage both spatial data and non-spatial data management and integrating platform in the soil and water loss monitoring system. This paper expounded the detail about the design technique and framework of the database in practice, and focused on manipulating the huge volume spatial geographic information system. Finally, 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 on soil eroded land, and especially for which needs to manage both spatial data and non-spatial data.
