浅析高分辨率遥感影像在地质灾害调查中的作用

High Resolution Remote Sensing Image Role in Geological Hazard Survey

本文以上饶县1∶5万地质灾害调查项目为基础,通过遥感调查进行分析总结,对遥感技术对整个项目中的作用进行了相关论述。项目手段主要利用最新高分辨率航空遥感影像为基础不仅对地质灾害的解译标志进行建立,并进一步讨论遥感技术在整个项目中发挥统筹规划的作用。高分辨率遥感影像不仅在宏观上对整个大型地质灾害调查项目的整体进度和调查质量进行全局把控,还能在微观上对调查点进行解译分析,最后还能结合其他专业信息进行数据融合分析。实践证明,有效的利用遥感技术能够在整个地质灾害调查项目中切实做到统筹兼顾。

This paper, taking shangrao county 1：50000 geological hazard survey as the foundation, through remote sensing investigation analysis summarized, on the role of remote sensing technology to the whole project related in this paper. Project means mainly using the latest high resolution remote sensing images based on not only to establish explanatory indication of geological disasters, and further discuss the remote sensing technology plays the role of overall planning in the whole project. High resolution remote sensing image not only on macro geological disaster investigation on the project＇s overall global controls the pro^ess and quality of survey, also on the microscopic interpretation analysis was carried out on the site, the final data fusion can also be combined with other professional information analysis. Practice proves that the use of remote sensing technology can effectively in the whole geological disaster survey project to be balanced.
