SPOT 5影像数据在伊犁谷地地质灾害遥感调查中的应用

APPLYING SPOT 5.IMAGE DATA TO SURVEY OF REMOTE SENSING OF GEOLOGICAL DISASTERS IN GONGLIU AND XINYUAN COUNTY IN OF THE YILI VALLEY

遥感技术已成为区域地质灾害及发育环境宏观调查不可缺少的技术之一,在滑坡、崩塌、泥石流等地质灾害调查、监测和研究工作中发挥重要作用.本文简要介绍应用法国SPOT5卫星影像数据进行地质灾害遥感解译调查与监测,按照建立地质灾害遥感解译标志、室内遥感解译、野外实地验证、室内再解译的技术路线,共解译出滑坡、泥石流灾害点1505处,并对灾害重点片区进行详细遥感调查.通过野外验证取得较好应用效果.SPOT5影像数据不但满足1∶5万地质灾害遥感解译,且完全满足1∶1万重点片区地质灾害遥感解译.

Remote sensing technology has become a regional geological disasters in the macro environment and its investigation of the indispensable one of the advanced technology in the landslides, collapses, landslides and other geological disasters of the investigation, monitoring and research work has played an important role. This paper introduces the application of the French SPOT 5 satellite image data interpretation of geological disasters in remote sensing survey and monitoring, In accordance with the establishment of geological disasters in remote sensing interpretation signs, indoor remote sensing interpretation, the wild-site verification, an indoor re-interpretation of the technical line, to a total interpretation of landslides and mud-rock flow disaster, 1505, also focused on disaster Area carried out a detailed remote sensing survey, field verification has been made through the application of better results. SPOT 5 image data not only to meet the 1 ： 50 000 geological disasters in remote sensing interpretation, and fully meet the key Area of 1：10 000 geological disasters in remote sensing interpretation.
