摘要
针对Landsat5-TM遥感影像植被监测方法进行了研究,采用了变化向量分析方法,通过分析采用绿度指数GVI和垂直植被指数PVI来进行植被检测,并通过最大类间方差进行阈值的选取,采用Landsat5-TM遥感影像数据进行了试验,通过变化检测分类图和变化类别图斑统计的方法对结果进行了评价,变化检测分类精度较高。
This paper studies vegetation monitoring methods based on the Landsat5-TM remote sensing images using the change vector analysis method through the analysis of GVI and PVI to detect vegetation.The threshold selection is conducted by Otsu and Landsat5-TM remote sensing image data are tested.The result is evaluated by the change detection and change category classification map,which shows that the change detection has higher classification accuracy.
