基于CBERS02的毕节地区植被覆盖信息提取技术研究

A study of extracting vegetation coverage in Bijie prefecture based on CBERS02 image

阐述了基于CBERS02数据采用植被指数的方法来提取植被覆盖度的过程,在ArcGIS空间分析中叠加功能的支持下,实现初步植被覆盖度图与土地利用方式的叠加,将各幅矢量数据进行镶嵌与拼接,最终得到整个毕节地区1:5万的植被覆盖图。

This paper expounded the process of extracting vegetation index based on CBERS02 data with the support of space analysis function in ArcGIS. The superposition of vegetation coverage and land use was realized preliminarily. Finally we obtained the 1/50,000 vegetation coverage by mosaic of vector data for the whole Bijie prefecture.
