| 摘 要： | 航天遥感技术的发展为地质学家提供了大量可使用的遥感数据.在这些遥感数据中,ASTER具有从可见光到热红外的较宽的波谱范围,能满足对大多数矿物、岩石划分的需要.ASTER的多波段数据除了可以用传统的数据处理方法处理之外,还可以利用高光谱的岩矿信息识别与提取技术进行数据处理,得到更精确的矿物、岩石分类结果.利用GIS评价模型处理ASTER遥感解译的蚀变岩石信息,可以得到精确的遥感异常,从而指导找矿勘查工作.

| Abstract: | The development of the space remote sensing technology provides a wealth of usable remote sensing data for geologist. In these remote sensing data ASTER has broad spectral bandwidths from VNIR to TIR and can meet the requirements for classifications of most minerals and rocks. In addition to the conventional data processing methods, the hyperspectral techniques for rock and mineral information recognition and extraction may also be used to process the multiband data of ASTER and yield more accurate mineral and rock classification results. The GIS evaluation model may be used to process altered rock information interpreted by ASTER, which may produce accurate remote sensing anomalies and guide mineral exploration. |
