【摘要】 本文论述了在缺少地面控制点的情况下，进行南极卫星影像数字制图的方法和技术。利用ＴＭ和ＭＳＳ卫星影像数据，制作了从中山站至南极点大剖面考察区内的１∶２０万卫星影像图。南极景观以冰雪地貌为主，冰雪在卫星影像上亮度极大，反差极小，导致条带噪声干扰严重。另一方面，裸岩地、海水与冰雪之间的反差又过大，细貌被压抑，这些又给影像处理造成很大困难，针对这些特点，本文叙述了从影像中提取噪声谱后利用方向滤波法消去条带噪声。基于自动识别理论进行分类增强，采用相关匹配和加权平滑法进行不同时期卫星影像镶嵌等几项特殊处理技术。更多还原

【Abstract】 For lack of detailed and accurate maps,it makes reseach work in an-tarctica difficult.Using TM and MSS imagery,the photographic maps in scale1∶200,000 of Greate Profile zone from Zhongshan Station to Antarctica Pole havebeen completed, These maps provide strong support to Chinese investigation in An-tarctica.There is description of methods and technologies for digital mapping of An-tarctica in Present paper.Ice and snow dominate the land features in Antarctica,the great brightnessand poorcontrast of ice and snow and streaking noise in satellite images make theprocedure of image processing difficult.On the other hand however, the contrastbetween bare rock land/sea water and ice/snow is so high that the details of ima-ges will be overcompressed.In the light of characteristics of satellite image in Antarctica,a filtering to re-move streaking noise has been discussed. Based on automatic identify classificationto enhance the details of objects and the methods and theory of digital rectifica-tion of satellite images using satellite positioning data and ground control pointsmeasured from field survey are also presented.更多还原
