IKONOS卫星影像在甘肃省红会煤矿区塌陷群识别中的应用

Application of IKONOS satellite images to recognition of the ground collapses in Honghui coal mine,Gansu Province

遥感技术在地质灾害的调查中有着广泛地应用,特别是高分辨率卫星影像。本文采用IKONOS高分辨率卫星影像,通过正射校正、影像融合后,获得高精度的遥感影像,作为解译地质灾害的遥感数据源,可以快速、准确地识别红会煤矿区的塌陷群,并能够清楚地识别塌陷及其细节特征,分析其影响因子、规模和危害程度,取得了良好的效果。

The high-resolution satellite images as one of remote Sensing techniques have been widely used to the investigation of geologic hazard.In this paper,the high-resolution IKONOS sensing images are carried out by means of orthographic correction processes and images fusion of the IKONOS satellite images.These images as the remote sensing data sources for the interpretation of geologic hazards have assisted in the rapid and accurate recognition of sizes,impact factor and risks of the ground collapse in Honghui zone,Gansu,which achieved good results.
