摘要
为验证遥感技术在国产高分卫星土地利用信息提取方面的应用效果,本文分别运用阈值法、波谱间关系法、NDVI对示范区的单个地类信息进行提取试验,运用非监督分类法、面向对象法进行全要素信息的提取,并对提取结果进行精度验证。试验表明,在单个地类信息的提取方面,3种方法有各自的提取优势以及对应的地类信息;在全要素信息提取方面,非监督分类法和面向对象法在各个地类信息的提取精度上有差异。
In order to verify the application effect of remote sensing technology on the land utilization information extraction of domestic high-resolution satellite,the threshold method,spectrum method and NDVI are used to do the information extraction test on single land class of the study area,whereas the unsupervised classification method and object-oriented method are used to extract information of all factors and the accuracy of extraction results are verified. The results show that three methods have their respective extraction advantages and corresponding land class information in the extraction of single land class information. For information extraction on all factors,there are differences in the accuracy of each category of information extraction between unsupervised classification and object-oriented method.
