摘要
本文运用无人机与国产高分技术获取了"6·24"茂县特大滑坡灾区数据源,分析了本次滑坡成因,利用无人机航摄数据与国产高分遥感数据开展了灾区受灾前后灾情对比,结合本次滑坡事故形成过程及受灾情况等信息,初步判识出灾区周边有4处疑似地灾隐患点。结果表明,无人机与国产高分技术相结合,可实现灾区应急地形生成与形变监测,对地灾潜在隐患的早期识别、发现及滑坡灾后灾情应急监测具有一定的指导意义。
This paper uses UAV and domestic high score technology to obtain the data source of ＂6 · 24＂ Maoxian landslide disaster area, analyzes the causes of this landslide, and makes use of UAV aerial data and domestic high score remote sensing data to carry out disaster area before and after disaster Comparison of the situation, combined with the formation of the landslide accident and the disaster situation and other empirical information, the initial identification of the affected areas around the four suspected disaster points, it is recommended to strengthen its focus on patrol investigation and follow-up monitoring, which guide the landslide disaster emergency Monitoring has a certain scientific.
