Abstract

Building three-dimensional geographic information system(3DGIS) for landslides has become essential for geological disaster prevention and mitigation during the construction and operation of large reservoirs. With landslides in several large reservoirs in Southwest China as research object and on the basis of 3DGIS system framework design, we present the data integration and management plan for reservoir landslides which is centered on GIS spatial database and consisted of relational database & multimedia-document base. Furthermore, we elaborate on the technical framework of 3DGIS which is based on Skyline, and describe the main functions including 3D scene browsing of reservoir region, landslides query and spatial location, browsing of landslide information, dynamic data update and management. Overall, a complete and effective data integration management platform with a fully functional three-dimension space information system is built in the 3DGIS for reservoir landslides in Southwest China. It is of practical significance for the informational management of reservoir landslides.
