Design and Implementation of Asian Seismic Risk Assessment Data Management System Based on ArcSDE

摘要

Asia is an earthquake-prone continent in which earthquakes cause huge losses of lives and property. Efficient data management is and important basis for seismic risk assessment which can effectively improve the post-earthquake emergency response capacity to reduce disaster losses in Asia. Seismic risk assessment needs basic geographic data, remote sensing data, earthquake thematic data, seismic case data and documents data. In this paper Asia seismic risk assessment database construction content, database logical architecture, physical architecture are well designed, and base on the database design the Asia seismic assessment data management program are developed. In order to achieve the seismic risk assessment, the database needs many kinds of large volumes of data, and the data management needs to be efficient and convenient. In recent years, development of GIS technology, spatial database technology and computer technology provides an important foundation for the efficient management of seismic risk assessment data. This paper uses traditional relational database and spatial database engine (SDE) to complete the risk assessment database construction. A data management system is developed which achieves efficient data storage, management, display and processing. The database together with the data management system provides an important support for the Asian earthquake risk assessment.
