摘要
航天干涉成像雷达技术是最近几年发展起来的对全球进行3维地形快速测图的高新技术,它标志着空间遥感技术从2维信息获取进入到3维信息获取的新阶段。本文以从SRTM数据中提取长沙市数字高程模型为例,介绍了通过逐步处理SRTM数据,得到应用于实践中的数字高程模型。同时还简要介绍了处理数据过程中所使用的一些软件,如Surfer,MATLAB,ENVI等。
Shuttle Radar Topography Mission Technique is a new technology about three dimension global surveying,which developed in the last few years, and it is the first radar system that picking up three dimension earth imaging in the history of human. Taking the process of extracting DEM data of Changsha city from SRTM data as an example,thisarticle particular introducedthe process of extracting DEM data used in appliance from phasing in SRTM data. Moreover,the article also introduced some software which are used in the process of dealing with data , such as the Surfer, MATLAB, ENVI, etc.
