idl获取影像面积

IDL ENVI用于定量遥感,有源代码，还有数据，对于学习定量遥感和idl编程很有帮助(idl and envi application)

coordinate transformation code of IDL_from ECI coordinate to GEO coordinate

说明：  运用MVC方法将逐日NDVI合成为月合成NDVI(Daily NDVI is synthesized into monthly NDVI by MVC method)

由遥感图像的日数据生成旬数据，一是输出旬数据总和，二是输出旬数据平均值(From the date of remote sensing image data generated late data, the sum of ten days one output data, the second is the average of the output data late)

IDL读取NEtCDF格式文件，NetCDF 文件的基本组成为变量、属性和维数(IDL reads files in NEtCDF format. The basic components of NEtCDF files are variables, attributes and dimensions)

说明：  这个可以做calipso垂直分布，是idl编程的，十分好用(This can do CALIPSO vertical distribution, IDL programming, very useful)

用IDl编写的，用IDL图像处理。已调试好的程序。(Prepared using IDL with IDL image processing. Debugging process has been good.)

串口采集数据程序，能够获取串口发来的数据，并自动滤波，显示波形。(Serial data acquisition program)

说明：  《遥感数字图象分析与编程》一书的课程ppt，附有详细IDL开发及MALTAB开发方法和例子。(&quot Remote sensing digital image analysis and programming,&quot a book of course ppt, with detailed IDL development and MALTAB development methods and examples.)

图像A中0表示水体，1表示植被，2表示裸地；B中4表示水体，2表示植被，1表示l裸地。 本程序将B的分类编码改成和A一致；以A为参考图像生成参考矩阵；计算总体精度和kappa系数。(Image A shows water body in 0, vegetation in 1, bare land in 2, water body in 4, vegetation in 2 and bare land in 1. In this program, the classification coding of B is changed to the same as that of A, the reference matrix is generated with A as the reference image, and the overall accuracy and kappa coefficient are calculated.)
