基于多源遥感数据的水体提取方法研究

Research on Water Extraction Method Based on Multi-source Remote Sensing Data

为了进一步减少洪涝灾害给国家造成的不利影响,必须进一步对洪涝灾害开展必要的研究和监测。有效获取水体数据以及洪水覆盖区域是洪涝灾害监测和研究的前提。卫星遥感技术具备能广泛收集信息、迅速收集相关数据、周期小以及数据量庞大等特点,所以被广泛运用于洪涝灾害的监测中。当前,在使用遥感技术的基础上对水体数据开展监测提取的方法有很多,但也存有相应的问题——只是单纯的运用传感信息源,并没有进一步对多元信息的组合开展运用,基于这一点,数据获取的最终结果也常常会受到天气和空间位置的影响。基于此,文章对多源遥感数据的水体提取方法进行研究,以供参考。

In order to further reduce the adverse impact of flood disasters on the country,it is necessary to further carry out necessary research and monitoring on flood disasters.Effective acquisition of water body data and flood coverage area is the premise of flood disaster monitoring and research.Satellite remote sensing technology has the characteristics of widely collecting information,rapidly collecting relevant data,small cycle and large amount of data,so it is widely used in flood disaster monitoring.At present,there are many methods to monitor and extract water body data based on remote sensing technology,but there are also corresponding problems-only using the sensing information source,but not further using the combination of multiple information.Based on this,the final result of data acquisition is often affected by weather and spatial location.Based on this,this paper studies the water extraction method of multi-source remote sensing data for reference.
