摘要
作为测绘科学的数字化产品,DEM在各个领域都有很广泛的应用。利用IRS-P5立体像对提取DEM已经成为近年来DEM提取研究的热点问题。本文介绍了DEM的建立方法,重点论述在IRS-P5影像基础上建立DEM数据的基本原理和过程,然后通过使用ENVI5.0对IRS-P5遥感立体像对影像进行加工,处理,编辑之后生成DEM。
As a surveying and mapping digital products,DEM in various fields have a very wide range of applications.IRS-P5 stereo image pair extraction DEM has become a hot issue in recent years.This paper introduces the establishment method of DEM,focusing on the basic principle and process of establishing DEM data based on IRS-P5 image.Then through the use of remote sensing ENVI5.0 of IRS-P5 stereo pair images for processing,handling,DEM generation after editing.
