在地震采集前 ,若能合理地使用遥感信息 ,即使是相对较昂贵的超光谱数据 ,也能节省大量时间和金钱。遥感技术应用范围的扩大主要是由于提高了对遥感数据的熟悉程度和数据更容易获得。目前两类令人关注的应用是 :裂缝作图和分析 ,探测地表渗漏的油气。美国怀俄明州的PowderRiver Even with relatively expensive hyperspectral data, significant savings in time and money can be realized if the remote sensing information is used reasonably well before the earthquake is acquired. The expansion of the application of remote sensing technology is mainly due to increased familiarity with remote sensing data and easier access to data. At present two types of applications of concern are: Crack mapping and analysis to detect oil and gas leakage from the earth’s surface. PowderRiver, Wyoming, USA
