城镇建设用地遥感影像提取方法的对比研究--以毕节市七星区为例
Comparative Study of Urban Construction Land Extraction from Remote Sensing-A Case Study of Qixing District,Bijie City
摘要
Abstract
The urban built-up information in Qixing District,Bijie City was extracted and analyzed using the NDBI index ,IB index and NBI index from TM image on Nov.15,2013.Besides,the corresponding year urban land area extraction accuracy was validated with confusion matrix array . The results showed that the NBI index algorithm is better than other construction index algorithms for extracting the construction land information with high accuracy and small error,which can be more accurate for extracting the information of construction land with NBI index .关键词
