经3 m空间分辨率TerraSAR图像在四川攀枝花地区1∶50 000区域地质调查中的应用,提出了一套基于TerraSAR图像的应用影纹-结构影像单元进行区域地质填图的基本方法。介绍了TerraSAR图像的解译分区、解译标志的建立方法、地质体影像单元的划分及三大岩类和构造的解译方法。根据研究结果,提出不将TerraSAR图像作为区域地质调查的首选数据源的建议。
According to the application of TerraSAR image(3 m resolution) in 1∶50 000 scale regional geological survey of Panzhihua area,Sichuan,the author proposed a regional geological mapping method on using image textures-structure image unit,based on TerraSAR.It introduced the interpretation division of TerraSAR image,the creation of method on interpretation signs,the division of geological image unit,and the method for interpretation of sedimentary—magmatic—and metamorphic rocks and structure.According to the studied results,the author suggested that the TerraSAR images would not be as the first choice in regional geological mapping.
