| 摘 要： | 采用基于地理坐标的镶嵌方法和剪切线的方法对两幅MODIS遥感影像做镶嵌时,在影像接缝处出现了黑色条带,条带值显示为-NaN或者0。主要针对这一现象介绍在IDL 7.0环境下编写的Delete_NaN程序和Delete_0程序的应用。该程序实现了消除黑色条带,并找回了丢失的数据,该程序运行速度快,操作简便,特别适用于MODIS遥感数据的影像镶嵌图。

| Abstract: | Based on the geographical coordinates of the mosaic methods and shear line on the way to do two MODIS remote sensing images mosaicing.There appears a black strip in the seams.Strip shows that the value is-NaN,or 0.This paper describes the Delete_NaN program and the Delete_0 program in the IDL 7.0 environment.The programs achieve the elimination of the black strip.and get back the lost datum.The programs run fast,and easy to operate.The programs are particularly adapt to in application of the MODIS remote se... |
