| 摘 要： | Landsat7 ETM+是陆地卫星系列的最新数据,其突出优势在于提高了多光谱波段的空间分辨率,增加了一个分辨率为15 m的全色波段,丰富了数据的信息量。选取长江三峡库区的两景ETM+原始数据,基于不同的地学遥感应用要求,试验性地研究了Landsat7 ETM+新型数据的数字处理方法,并比较了这些处理方法的应用效果。结果表明,选择适当的数字方法对新型Landsat7ETM+遥感数据进行处理,能够快速、有效地获得同时具备较高的光谱分辨率和空间分辨率的遥感数字图像,显示出较好的应用优势。

| Abstract: | Landsat-7 ETM+ is the latest the landsat series data. Its outstanding advantage is its higher spatial resolution in multi-spectrum band. It adds a new panchromatic band with a resolution of 15 meters,and enriches information of data. Considering geographic application requests, this paper selects ETM+data of two scenes of Three Gorge Reservoir Area, studies the processing methods of Landsa7 ETM+ data and compares the results of different processing methods. The study shows that processing the new type remote sensing data--Landsat7 ETM+, with appropriate digital method can obtain remote images with higher spectrum resolution and higher spatial resolution and shows great advantage in application. |
