摘要
SPOT多光谱影像仅有4个波段,光谱信息相对较少,通常的水体提取方法受到波段数的限制,通过波段合成增加SPOT多光谱影像可用的波段数,不仅增加了水体提取方法的种类,而且,通过对矿区塌陷地积水现象进行水体提取试验,结果表明:波段合成对SPOT影像的水体提取情况有一定程度的改善,水体提取更完整,误提现象较少。
SPOT multispectral image only has four bands, spectral information is rela tively small, is not conducive to use the usual water extraction methods based on the rela tionship between bands. By band synthesis to increase SPOT image band number, not only increase the water extraction methods, but make extraction experiment of mine subsidence water phenomenon. It shows that the extraction results have some degree improvement, wa ter extraction more complete and error extraction phenomenon less.
