Python遥感图像处理应用篇(二)：Arcpy遥感图像LWSI指数计算批量处理

1.使用数据MOD09A1

2.NDVI指数计算公式

The MODIS sensor has 36 spectral bands, seven ofwhich are designed for the study of vegetation and landsurfaces: blue (459–479 nm), green (545–565 nm), red(620–670 nm), near infrared (NIR1: 841–875 nm; NIR2:1230–1250 nm), and shortwave infrared (SWIR1: 1628–1652 nm, SWIR2: 2105–2155 nm). Daily global imageryis provided at spatial resolutions of 250-m (red andNIR1) and 500-m (blue, green, NIR2, SWIR1, SWIR2)
这里选择第2波段和第6波段进行计算。

3.Modis数据整理

把MOD09A1处理出来的数据分别按照波段对应放在下面两个文件夹里面：
