高分遥感数据结合三维技术在东昆仑地区地质调查中的应用

Application of high-resolution remote sensing data combined with 3D approach geological investigation in the eastern Kunlun mountain area

文章以东昆仑地区为例,论述了通过高分遥感数据结合三维技术解决在遥感地质调查中平面图上无法解译地质特征这一问题。选用WorldView-2遥感数据作为数据源,结合三维技术,形成纹理信息丰富的三维立体图像,对断层规模、性质、断面产状等构造信息进行遥感地质解译,对不同地质体的空间位置、接触关系进行解译。通过野外调查断层性质、断面产状等特征与三维遥感解译结果基本一致。研究结果表明通过三维遥感影像开展遥感地质解译准确性较高,能够反映大量平面图上难以表达出来的地质信息,是遥感地质调查中一个重要的技术手段。

The interpretation of high resolution remote sensing data combined with 3D approach can solve the problem which ex- ists in the 2D planar graph. Taking the eastern Kunlun mountain area as a case study, the WorldView-2 remote sensing data was se- lected for the study. By applying the 3D approach, 3D remote sensing image was generated with rich texture information, which help to interprete the size, property, attitude of fault plane as well as the spatial distribution and the contact relationship of geological body. The interpreted results of fault property and attitude are identical with field investigation results. The study results show that the accura- cy of remote sensing interpretation combining with 3D approach is higher than the traditional 2D plane image interpretation, this ap- proach can reflect various of geological information and become an important technology in remote sensing geological investigation.
