摘要
为了推动国产高分卫星数据在我国地质灾害遥感调查中的应用,以环境地质灾害易发、多发的重庆市三峡库岸万州段作为典型研究区域,在收集该区地质灾害资料及现场调查结果的基础上,对研究区高分二号影像进行一系列预处理,然后将前期野外实测数据与影像底图进行叠加处理,分析和总结地质灾害的形成条件以及其分布在遥感影像上的光谱和几何特征,建立地质灾害遥感解译标志,根据解译标志对研究区进行地质灾害遥感解译,解译结果在野外得到验证。研究表明:国产高分遥感数据可以为地质灾害调查提供数据支持,适用于地质灾害遥感调查与监测。
In order to promote the application of domestic GF-2 satellite data in geological hazards survey and monitoring,Wanzhou district in Chongqing city was selected as a typical research area to collect geological hazards and field survey data.based on a series of preprocesszing on the image obtained by the GF-2 satellite i,the field measurement data and the image base map were superimposed.then the formation conditions of the geological hazards were analyzed and summarized,the spectral and geometry features distributed on the remote sensing image were also defined,and finally the geological hazards remote sensing interpretation signs were established.The landmarks of geological hazards were described in detail.the interpretation results were verified in site.It is found that GF-2 can provide technical support for geological hazards investigation,it is very suitable for remote sensing survey and monitoring of geological hazards.In future geological hazards investigation,the combination of indoor interpretation and field investigation can be used.
