Landslide monitoring produces large amounts of data that can hardly be processed and analyzed manually. So an information management system is used for the management

search and analysis of monitored data. Traditionally the system is based on relation database (RDB) and can’t be easily used for the processing of spatial information. The authors developed a GIS-based management and analysis system for landslide monitoring information with Map Objects (MO)

which can integrate spatial and monitoring information of a landslide to implement functions as data management

search and multiple visual analysis. The system can also run independently and can be customized in accordance with particular landslide and its monitoring program

thus making it as a general tool for landslide research. In the paper

the structure design and implementation of the system are discussed; and then its application to Xietan landslide of the Three Gorges reservoir area is described.
