灾害监测与评估中多源数据综合应用的设计与实现

The Design and Implementation of Integrating Multi-Source Data in Disaster Monitoring and Assessment

摘要: 随着“大数据”时代的来临以及数据挖掘技术的快速发展，人们面对的数据也越来越复杂，这些数据在数据格式、存储结构和分发方式等方面都存在较大差异，给多源数据的共享和应用带来了极大的不便，目前这种现象在灾害监测与评估业务中表现得极为明显。本论文在此背景下结合减灾中心“灾害监测与评估业务平台建设”项目，分析了系统内各类数据分发应用的现状和现有数据应用方式的不足，探讨了灾害监测与评估业务中多源数据综合应用的解决思路，提出了基于地图和数据内联关系的多源数据综合应用方案，即以地图为多源数据的信息载体，通过数据间的固有联系，实现多源数据的综合应用，并据此设计和实现了“地震综合查询”模块，进一步论证了本文提出的多源数据综合应用的可行性和合理性。论文的最后对本文所作的研究工作进行了总结，并对进一步的研究内容进行了展望。

Abstract: With the arrival of Big Data era and rapid development of data mining, the data that people face is becoming more and more complex, and showing significant differences among the data format, storage structure and distribution mode, which has brought great inconvenience for multi-source data sharing and application. At present, this phenomenon is very obvious in disaster monitoring and assessment of business performance. Under this background, this paper analyzed the current situation of application in all kinds of data distribution system and the shortage of the existing data application way combined with disaster mitigation center “disaster monitoring and evaluation of business platform construction” project, discussed the disaster monitoring and assessing the integrated application of multi-source data of business solution, presented multi-source data comprehensive application solutions based on the map and data inline relationship, i.e., according to the map for multiple source data information carrier, realized the comprehensive application of multi-source data through the inherent links between the data, and on the basis of the design and implement the “earthquake comprehensive query” module, further demonstrates that the integrated application of multi-source data presented by this paper is feasible and rational. In the end, the paper summarized the research work done in this paper, and discussed the contents of further research.
