滑坡泥石流灾害危及人身和财产安全,灾后第一时间获取现场影像资料进行灾害解译是抢险救灾的关键。基于高效免控制点的实时DGPS技术,第一时间获取灾区影像成果,通过内业数据处理获得DOM和DEM成果,和灾前数字成果对比分析,根据受灾范围的确定、数字统计和次发灾害等情况,对受灾程度进行判断,为领导决策提供有力的依据。实时DGPS辅助低空遥感这一新技术在防灾救灾方面具有广阔的应用前景。
Landslide debris flow hazards endanger the personal and property safety, the first time after the disaster to obtain live video data for disaster interpretation is the key to disaster relief. Real-time DGPS technology based on efficient control points free of charge, the first time to get the results of the disaster area images, DOM and DEM results obtained by the internal data processing, and the comparative analysis of the digital results before the disaster, according to determine the scope of disaster, digital statistics and secondary disasters Situation, to judge the extent of the disaster, to provide a strong basis for decision-making. The new technology of real-time DGPS-assisted low-altitude remote sensing has broad application prospects in disaster prevention and relief.
