基于多源灾情数据的地震灾害损失实时动态评估系统设计与实现

Design and Implementation of Real-time Dynamic Assessment System of Earthquake Disaster Loss Based on Multi-source Disaster Data

摘要:

传统的地震灾害损失评估系统，由于基础数据更新不及时，其评估结果准确性较差；随着灾情获取手段的不断丰富完善，利用地震现场实时获取的多源灾情信息，能够实现地震灾害损失实时动态评估。本文通过系统架构、业务功能、业务流程等设计，完成了多源灾情数据的地震灾害损失实时动态评估原型系统的研发。系统的设计与实现有助于震后政府部门实时动态地了解和掌握建筑物破坏、人员伤亡、经济损失等关键灾情信息，能更好地服务于抗震救灾工作。

Abstract:

Since the basic data usually could not be possible to update in time, it is difficult for traditional earthquake disaster loss assessment system to provide accurate assessment results. With increasingly improving technological means, it is the time for us to be able to achieve real-time earthquake disaster loss assessment by using satellite-drone-ground multi-source disaster information obtained from earthquake sites. Through the design of system construction, service function and service procedure, a prototype system has been developed to provide real-time earthquake disaster assessment based on multi-source disaster data. This system is helpful for government to obtain real-time disaster information (including degree of building damage, casualties, economic loss and so on), as well as to carry out earthquake and disaster relief work.
