The following table describes the supported platforms and operating systems for IDL.aFor UNIX and Mac OS X, the supported versions indicate that IDL was either built on (the lowest version listed) or tested on that version. You can install and run IDL on other versions that are binary compatible with those listed.b The LINUX version of IDL is built on RedHat 4. If your version of Linux iscompatible with the listed kernel and glibc versions, you should be able to install and run IDL.c The IDL Workbench requires the GTK+ library version 2.4 or later. Printingfunctionality in the Workbench requires GTK+ library version 2.10 or later. If GTK+ version 2.4 or later is not available, IDL will only run in console mode.d On 64-bit Linux systems, the IDL Workbench requires that your platform’s 32-bitcompatibility libraries be installed.eThe IDL Workbench and Online Help are not supported on Solaris x86 64-bit machines. Documentation is available on the DVD for Solaris x86 platforms.PlatformVendorHardwareOperating SystemSupported VersionsWindowsMicrosoftIntel/AMD x86 32-bit Windows XP SP2, Vista Intel/AMD x86_64 64-bitWindows XP SP2, Vista Macintosh aApple PowerPC 32-bit OS X 10.5.1Apple Intel 32-bit OS X 10.5.1AppleIntel 64-bit OS X 10.5.1UNIX aSUN SPARC 32-bit Solaris c 10SUN SPARC 64-bitSolaris c 10SUN Intel/AMD x86_64 64-bit Solaris e 10various Intel/AMD x86 32-bit Linux b, c Kernel version 2.6.9 glibc version 2.3.4 gtk2 version 2.4.13variousIntel/AMD x86_64 64-bitLinux b, c, dTable 1-1: Hardware Requirements for IDLChapter 1: System Requirements9 32-bit and 64-bit VersionsOn UNIX and Macintosh Intel platforms that provide 64-bit support, you can run IDLas either a 32-bit or a 64-bit application. When both versions are installed, the 64-bitversion is the default. You can run the 32-bit version by specifying the -32 switch atthe command line, as follows:% idl -32or% idlde -32Under Microsoft Windows, the 32-bit and 64-bit versions are started via separateStart menu entries.On Macintosh Intel 64-bit machines, you can double-click on the 32-bit Macintoshapplescript (.app) files.Graphics HardwareSome IDL features take advantage of graphics hardware that supports the OpenGL2.0 interface to improve rendering performance, if such hardware is present. Yourvideo card should support OpenGL 2.0 or higher to take advantage of these features.Be sure to update your video card drivers with the most recent version.Platform Support Questions and AnswersThis topic describes the platform support requirements for IDL 7.1.

envi镶嵌方法
envi镶嵌方法ENVI (Environment for Visualizing Images) 是一款专业的遥感图像处理软件，提供了一系列强大的图像处理和分析工具。
在ENVI中，你可以使用镶嵌（Mosaic）功能将多个图像拼接在一起，形成一个更大的图像。
以下是使用ENVI进行图像镶嵌的一般步骤：1. 打开ENVI：首先，启动ENVI软件。
2. 打开图像：在ENVI的菜单栏中，选择“File” -> “Open”，然后选择你想要镶嵌的图像文件。
你可以一次打开多个图像。
3. 创建Mosaic Dataset：在ENVI的菜单栏中，选择“Image” -> “Mosaic”，然后选择“Create Mosaic Dataset”。
4. 设置Mosaic Dataset参数：在弹出的对话框中，你可以设置各种参数，如投影、坐标系、分辨率等。
这些参数将决定最终镶嵌图像的属性和质量。
5. 添加图像到Mosaic Dataset：在“Add Images”部分，选择你想要添加到镶嵌中的其他图像。
你可以按顺序添加图像，以确保它们按照正确的顺序排列。
6. 调整图像顺序和大小：在“Mosaic”工具窗口中，你可以通过拖动和缩放图像来调整它们的顺序和大小。
这有助于确保所有图像都能正确地对齐和拼接。
7. 应用Mosaic：一旦你对所有设置和图像位置满意，就可以点击“OK”来应用镶嵌。
这将创建一个新的镶嵌图像，你可以在ENVI中进一步查看和分析。
8. 保存结果：如果你满意镶嵌的结果，可以选择“File” -> “Save As”，将结果保存为一个新的图像文件。

高光谱分析
• 像元纯净指数(PPI) 纯净像元指数是一种在多波谱和高光谱影像中寻找波 谱最纯净的像元的方法。通过，波谱最纯净的像元与 混合的端元相对应。像元纯净指数通过迭代将N维散点 图映射为一个随机单位向量来计算。每次映射的纯净 像元被记录下来，并且每个像元被标记为纯净像元的 总次数也将被记录下来。这将生成一幅像元纯净影像 PPI，在该影像上，每个像元的DN值与像元被标记为 纯净像元的次数相对应。
基于影像自带几何信息的地理坐标定位
• 构建GLT（几何查找表） 几何信息查找表文件包含了行和列的对应信息，这样就 将输出影像中的每一个像素同输入影像联系起来。如 果GLT值是正值，那么就会进行精确的像素匹配。如 果GLT值是负值，无法进行精确的像素匹配，只能使 用最临近的像素进行匹配。 • 通过GLT纠正影像 • 通过IGM（输入几何信息数据文件）纠正影像
监督分类 • 平行六面体法 平行六面体使用一条简单的判定规则对多光谱数据进行分类。判 定边界在影像数据空间中是否形成了一个N维的平行六面体。平 行六面体的尺度是由标准差阈值所确定的，而该标准差阈值则是 根据每种所选类的均值求出。 • 最小距离法 最小距离分类使用了每个感兴趣区的均值矢量，来计算每一个未 知像元到每一类均值矢量的欧氏距离。除非用户指定了标准差和 距离的阈值，否则所有像元都将分类到感兴趣区中最接近的那一 类。
• 二值编码法 二值编码分类技术将根据波段值落在波谱均值的下方或 者上方的情况，把数据波谱和端元波谱编码为0或者1。 “异或”逻辑函数被用来将每一种编码后的参考波谱同 编码后的数据波谱进行比较，生成一幅分类影像。 • 波谱角法 波谱角填图分类法（SAM)是一个基于物理的波谱分类 法，它是用N维角度将像元与参考波谱进行匹配。该算 法将波谱看作是空间的矢量，矢量的维数就等于波段的 个数，通过计算波谱间的角度，来判断两个波谱间的相 似度。
