波段合成

劈窗算法计算地表温度，所用数据为landsat8 OLI(Surface Temperature Calculated by Split Window Algorithms)

根据影像的像素数及单个栅格的面积，求出栅格影像的面积

ndvi时间序列分析hants idl源码 主要用于ndvi平滑处理 消除云等噪声影响(Ndvi time series analysis hants idl source is mainly used for ndvi smooth processing To eliminate the noise effects such as cloud. )

栅格数据之间的相关性分析(相关性分析是指对两个或多个具备相关性的变量元素进行分析，从而衡量两个变量因素的相关密切程度。相关性的元素之间需要存在一定的联系或者概率才可以进行相关性分析。相关性不等于因果性，也不是简单的个性化，相关性所涵盖的范围和领域几乎覆盖了我们所见到的方方面面，相关性在不同的学科里面的定义也有很大的差异。)

说明：  利用IDL进行遥感图像的大气校正，详细说明等(Using IDL for atmospheric correction of remote sensing image, detailed description, etc)

The time series harmonic decomposition method fully considers the dual characteristics of vegetation growth periodicity and data itself when reconstructing images, and can reconstruct time series NDVI images with vegetation frequency curves representing different growth periods to truly reflect the regularity of vegetation periodic changes

IDL ENVI二次开发下批量打开landsat TM文件(Batch Opening of Lansat TM Files under IDL ENVI Secondary Development)

IDL中用于读取ENVI格式的遥感卫星影像数据的IDL程序(IDL, ENVI format for reading remote sensing image data on the IDL)

这个程序包里面包含读取遥感影像的IDL代码，可以读取多个波段，并且显示图像！(This package which contains the IDL remote sensing image to read the code, which can be read by a number of bands, and display images!)
