从航空遥感图像中综合利用河道的光谱特性和形态特性提取河道的方法。可以通过其光谱特性来大致确定河道，再依据河道的形态特性（长和宽），分为X和Y两个方向分别判断其形态，得到河道的信息。通过对上海市七宝地区航空遥感图像中河道的提取的实例，表明这是一种完全可行的河道提取方法。

This paper applies a new method which uses river＇s spectrum feature and shape feature to extract river from aerial remote sensing images. First, river＇ s feature is used to approximately extract the river. Secondly, River＇ s shape feature is ursed （length and width） and divided intoX and Y direction to ensure its shape. The test using aerial remote sensing images of QIBAO in, Shanghai. The results indicated that this is a reasonable method in automatic extracting rivers.
