摘要
针对当前森林火灾动态监测与预警中海量、异构、多源、动态的数据在存储、计算、管理方面所面临的挑战,以及国内外在森林火灾动态监测与预警上的研究往往只考虑单一领域或技术的问题,结合新兴的大数据分析与处理技术,融合林火动态监测与预警不同技术领域的研究成果,对林火多源异构数据采用混合处理方法,基于Hadoop和Spark大数据集成平台构建了一个森林火灾混合大数据分析系统。并设计一个林火火点检测实验,通过实验验证了该系统的可行性和有效性,可为后续研究和建立森林火灾动态监测与预警可视化大数据平台提供参考。
Considering the challenges in the storage,computing and management of multi-source and dynamic data of massive,heterogeneous,multi-source and dynamic data used in current dynamic monitoring and early warning of forest fires and the problem that the related studies at home and abroad often put the focus on a single aspect or technical problems,the paper took the hybrid processing method for the multiple heterogeneous data of forest fire and constructed a mixed big data analysis system based on Hadoop and Spark big data integration platforms by combining with emerging big data analysis and processing technology and integrating different research results of dynamic monitoring and early warning of forest fires. A forest fire detection experiment was designed to verify the feasibility and validity of the system,so as to provide references for following research and establishment of visualized big data platform for forest fire monitoring and early warning.
