▍1. RSEI
徐涵秋教授提出的遥感生态指数实现的IDL代码(It is the code for the RSEI indice,which is used to estimate the environment)
LandSat8的辐射定标与大气校正,envi5.3亲测可用(含FLAASH和QUAC)(Radiation calibration and atmospheric correction of LandSat8, envi 5.3 pro-test available (including FLAASH and QUAC))
说明: LandSat8的辐射定标与大气校正,envi5.3亲测可用(含FLAASH和QUAC)(Radiation calibration and atmospheric correction of LandSat8, envi 5.3 pro-test available (including FLAASH and QUAC))
envi软件,调用决策树,经过实测可用。前提装envi(envi software, called the decision tree, after the measured available. Premise equipment envi)
利用IDL编写的,实现了掩膜、 波段合成、 主成分分析 、缨帽变换、 水体指数(ndwi)、 归一化植被指数(ndvi)。面向对象方法写的(use idl language,come true mask、layer stacking、texture、tascap、pc、ndvi、ndwi)
利用idl写的根据遥感影像自动匹配的自动校正,调用envi自带函数envi_auto_tie_points_doit envi_register_doit(Use of remote sensing image idl write according to automatic matching of automatic correction, call envi bring their own function: envi_auto_tie_points_doit envi_register_doit)
说明: 处理遥感图形,将时间序列进行分布式线性拟合(Processing remote sensing graph and distributed linear fitting of time series)
说明: 依托ENVI软件,采用IDL语言编写,实现TM5影像辐射定标批处理,(Batch processing of TM5 image radiometric calibration)
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.)

提取neccdf文件的某一属性,输出为tif文件(transform *.nc to *.tif)
ENVI二次开发源码,可实现大气校正,融合,镶嵌等功能(ENVI development source code, you can achieve atmospheric correction, integration, mosaic and other functions)
将shp格式的GIS数据转为ENVI EVF格式(GIS data shp format to format ENVI EVF)
栅格化计算Hurst指数,用于水文、气象参数趋势的判断 水文、气象要素的时间序列分析中,一般下载到的程序是针对单个站点的H指数计算,得到的结果是单个H指数值 该程序实现时间序列栅格图像上每个点H指数的计算,得到的结果是单个栅格图像,栅格值是H指数值(a distributed pattern to calculate Hurst Index,the input is a series of grid datas, the output is a grid data each pixel value is a Hurst Index.)
