基于Google Earth影像图遥感解译在我国西北矿产地质调查中的应用

Application of remote sensing interpretation in geology and mineral resources survey based on Google Earth image in North-west China

在新疆扎河坝煤矿、买乌开、科克库都克三幅1∶50000区域地质矿产调查当中,笔者利用Google Earth(GE)图像数据进行了遥感地质解译,获得了满意的效果。在本次遥感解译工作中,所获得的GE卫星影像的清晰度远远大于以往的ETM多波段合成图像。其包含的可解译地质信息也比以往的卫星影像更加丰富。通过对GE影像进行数据采集、完美镶嵌、校正成为1∶5万标准图幅,使其坐标误差控制在30 m以内,并建立了测区内各地质构造单元的解译标志。良好的GE影像图的解译资料推动了野外工作的顺利进行。

In regional geology and mineral resources survey 1∶50 000 of Zhaheba coal mine,Maiwukai,kekeku Duke,Xinjiang autonomous region,the authors carried on the remote sensing interpretation by Google Earth(GE) image data and got a satisfied result.In this remote sensing interpretation working,the definition of the GE satellite image is far greater than ETM multiband synthetic image.The interpretative geologic information is much more than before.Through collecting data,mosaicking and checking by the GE image,the ...
