基于IDL与ENVI的MODIS遥感影像镶嵌

Mosaic of MODIS Data Based on IDL and ENVI

MODIS遥感图像镶嵌时,在图像接缝处出现黑色条带,且该处数据为无效值。在ENVI环境下利用IDL编程语言,消除黑色条带,并找回了丢失的数据,该程序运行速度快,操作简便,在MODIS遥感数据反演的大气水汽含量图像和地表温度图像的镶嵌图中得到了充分的应用。

Using two Modis remote sensing images to do mosaic,the seams in the image appear black belt,which shows the value as-NaN.In order to eliminating the black belt and recovering the lost data,we make a program in the ENVI environment using IDL7.0.The program achieves the function.The program runs fast and easy to operate.Especially suitable for the mosaics of the MODIS remote sensing data inversion of atmospheric water vapor content images and land surface temperature images.
