WebGIS Based Information and Decision-making Support System for Earthquake Disaster Reduction

摘要

The development of Earthquake Disaster Reduction System (EDRS) depends on the state of arts of computer technology, involving many fields of computer application skills and techniques. In this paper, first a key period after earthquake occurrence is discussed. Then a WebGIS based Information and Decision-making Support System (the System) for Earthquake Disaster Reduction is introduced, including of technical frameworks, function composition, structure of software, redevelopment languages, databases, and remote linking and calling of analysis modules. Meanwhile tested by a Ms5.1 earthquake in north-east China, the System showed the damage distribution maps, which include the comparison of isoseismals map and the damage of buildings map. Finally, several conclusions are presented.
