Abstract:

利用资源一号(ZY-1)02C卫星(以下简称02C星)全色高分辨率相机(HR)和多光谱相机(MUX)数据,以河北承德多金属矿区和江西寻乌稀土矿区为实验区,开展了1:5万矿山遥感监测应用研究;分析了应用过程中存在的问题,提出了解决方案和建议,对02C星数据在矿山遥感监测中的规模化应用起到了示范效果。研究结果表明:在数据处理流程上,对空间分辨率为2.36m的02C星全色HR1与HR2数据需先进行正射纠正再拼接,对空间分辨率为10m的多光谱数据MUX可采用假彩色合成方法进行模拟真彩色合成;在矿山地物识别上,与SPOT5图像比较,02C星图像可更好地反映出开采面、开采点、中转场和矿山建筑等矿山地物类型,不足之处是纹理信息较平滑、矿山地物的边界相对模糊,因而增加了室内解译的难度;在经济效益上,02C星数据的性价比优势明显。因此,尽管02C星数据处理和解译工作量较大,但其能满足1:5万矿山遥感监测要求,总体经济效益显著。
