摘要
介绍了激光雷达技术,分析了机载激光雷达的快速性、穿透性、主动性、高密度高精度、高效性、信息丰富等优点。以海地地震、汶川地震、飓风"艾克"为例概述了机载激光雷达技术在灾害管理中的研究和应用现状。分析了洪水、地震、飓风、滑坡、泥石流、森林火灾等自然灾害应对过程中,机载激光雷达在综合风险调查、灾害监测预警、灾害应急救援和救助、灾情损失评估和社会影响评价、灾后恢复重建等防灾减灾业务的应用潜力。展望激光雷达技术在提高我国综合减灾能力和风险管理水平中的应用前景——随着技术的进一步发展、数据获取成本的降低以及后续数据处理水平的提高,激光雷达技术将和其他的空间信息技术一起进一步提升我国综合减灾能力和风险管理水平。
In this paper, a brief introduction of airborne LiDAR technology and its advantages including speediness, penetration, initiative, high-density and high-precision, high efficiency, information-richness are given. Airborne LiDAR research and application status in disaster mitigation are illustrated by analyzing the usage of airborne LiDAR in Haiti Earthquake, Great Sichuan Earthquake and Hurricane ＂Ike＂. It＇ s potential applications would be in disaster prevention and mitigation activities comprising comprehensive disaster risk assessment, disaster monitoring and early warning, emergency rescue and disaster relief, disaster comprehensive assessment and social impact assessment, disaster recovery and reconstruction and etc. where floods, earthquakes, hurricanes, landslides, mudslides, forest fires and other natural disasters are included. Finally, application expectation of airborne LiDAR in China comprehensive disaster reduction and risk management is given with the further development of technology, reducing of data acquisition costs and improvement of data processing levels.
