摘要
本文根据TM影像多波段的特征,针对矿区小煤窑和水体难以区分的问题,利用谱间关系法和NDVI植被指数法,提取矿区的小煤窑,并通过航片以及野外实地调查对提取结果进行了验证,经验证提取的小煤窑样本全部正确,提高了土地利用/土地覆盖的分类精度。
TM image with multispectral data can be proved more effective to distinguish small coal mines from water in coal mine region with the NDVI modeling and multispectral relationship method.Air photo and field survey were used to evaluate the extracting results,and the samples of small coal mines were accurate.It could monitor the illegal coal mine and help to complete land reclamation plan successfully.
