摘要
针对内蒙古戈壁荒漠区特殊地貌地质填图工作,选择ASTER和SPOT5数据,通过图像融合、影像校正、影像增强等处理方法,提高图像的空间分辨率和光谱分辨率。利用遥感解译图像快速准确地获取地层、侵入体和构造的解译标志,通过遥感地质解译结合地面调查进行综合分析和解译,提高了填图的准确性,为特殊地质地貌区地质填图提供技术支持,对于在同类区域开展地质填图工作有指导意义。
In order to improve the spatial and spectral resolution of images,we adopt image fusion,image correction and image enhancement to process ASTER and SPOT5 data for geological mapping of special geological and geomorphic areas in Gobi desert of Inner Mongolia. As a result,interpretation markers for the stratum,intrusive bodies and structures can be established quickly and precisely. Then,the geological mapping accuracy can be improved after comprehensive analysis by combining field work and remote sensing image interpretation. So,this combination can be served as a guideline for geological mapping in similar areas.
