高光谱综合遥感考古方法研究——以长安-扈邑区考古为例

Study on Comprehensive Remote Sensing Archaeological Method Using Hyperspectral Data——A Case Study of Chang’an-Huyi Area

遥感技术具有广阔的视野和先进的技术手段,通过遥感技术能提取和解释出地面及地下肉眼难以发现的古遗址。采用以高光谱遥感为主要遥感技术手段,在长安-扈邑研究区进行地下文物遗存考古,通过对高光谱热异常、老航片立体解译微地貌等多种遥感手段综合分析,确定了9个规模较大的异常区域。陕西省考古研究所对其中8个进行了实地钻探验证,勘探证实了其中7处有古代墓葬或其它遗迹存,表明运用多重遥感技术寻找地下古代文化遗存有较高的准确性。

Remote sensing technology is characterized with a broad exploration range and advanced technical methods and it can extract and interpret ancient sites which are difficult to find with eyes on the ground and underground.Hyperspectral remote sensing was used in this study as technical method to explore the underground ancient cultural relics in Chang'an-Huyi research area.Through the detecting of hyperspectral thermal anomalies,using ancient vertical aerial photographs to analyze micro-landforms and other remote sensing methods for comprehensive analysis,finally nine large-scale anomalous regions were identified.Shaanxi Provincial Institute of Archaeology verified eight regions through field drilling and confirmed that seven regions had ancient tombs and other Cultural relics,which illustrates that it is an efficient way with higher accuracy to detect the underground ancient cultural relics using multiple remote sensing techniques.
