The Design and Implementation of Urban EarthquakeDisaster Loss Evaluation and Emergency Response DecisionSupport Systems Based on GIS

摘要

Based on the necessity analysis of GIS applications in earthquake disaster prevention, this paper has deeply discussedthe spatial integration scheme of urban earthquake disaster loss evaluation models and visualization technologies byusing the network development methods such as COM/DCOM, ActiveX and ASP, as well as the spatial databasedevelopment methods such as 0040 and ArcSDE based on ArcGIS software packages. Meanwhile, according toSoftware Engineering principles, a solution of Urban Earthquake Emergency Response Decision Support Systemsbased on GIS technologies have also been proposed, which include the systems logical structures, the technical routes,the system realization methods and function structures etc. Finally, the testing systems user interfaces have also beenoffered in the paper.
