遥感地质解译路线在西藏羌塘地区1∶5万区域地质调查中的应用

APPLICATION OF REMOTE SENSING ROUTINE INTERPRETATION FOR 1:5000 REGIONAL GEOLOGICAL SURVEY IN QIANGTANG AREA OF TIBET

区域地质遥感调查是近几年来一直采用的一种新的地质调查方法,最大特点是充分利用遥感图像的空间宏观优势,结合地面调查工作进行多层次的影像地质解译,在整体上提高对工作区区域地质特征的全面认识,解决突出的基础地质问题和与成矿有关的关键问题,加快填图速度,提高成图质量。目前,可应用的遥感数据种类多、波段丰富、分辨率高,遥感数据处理的技术和方法越来越先进,为高质量成图和深入解译奠定了基础。本文在总结了工作中遥感数据的采集、处理、解译、应用的基础上,提出了遥感地质解译路线的必要性和方法,进一步规范了遥感地质解译路线的内容和样式,为区域地质调查遥感地质解译路线编制提供参考。

Regional geological remote sensing survey has been used in geological survey in recent years. The most typical feature of this method is that it makes full use of the spatial macro advantage of the remote sensing image, which is combined with ground survey for the multi-level geological interpretation by image. On the whole, it is to improve the comprehensive understanding of the regional geological features of the working area, to solve the basic geological problems and the key problems related to mineralization, to speed up map plotting and to improve the quality of mapping. At present, the remote sensing data is rich variety, band, high resolution, the techniques and methods of data processing and more advanced, all these laid a foundation for high-quality mapping and interpretation. Based on the summary of the remote sensing data of acquisition, processing,interpretation. This paper proposes the necessity and method of the remote sensing geological interpretation route,Standardizes the content and style, provides a reference preparation course.
