摘　　要：以高分二号(GF-2)影像为基础,通过水体指数法与监督分类提取水体宽度,并利用河道实测断面建立水位与水面宽度的关联关系,进而获得目标水位的新型水位监测方法。实验表明,该方法人工干预较少,自动化程度高,精度能满足评估需要。In this paper,a new water level monitoring method based on GF-2 image data is proposed to extract water width through water index method and supervised classification,and the correlation between water level and water surface width is established by using the measured section of river channel,so as to obtain the target water level.Experiments show that this method has less manual intervention,high degree of automation,and can meet the need of evaluation accuracy.
