摘要：

本文依据南极地区Ｌａｎｄｓａｔ－ＴＭ影象各波段不同的光谱和空间特征，在ＡＲＩＥＳ数字图象处理系统上，提取高程信息和冰貌信息，并将栅格数据转换成矢量数据，建立图形间的拓扑关系。经ＲＡＭＳ图形信息处理系统编辑和修饰，由计算机输出线划冰貌图。最后对该地区冰貌的形成、分布特点及其变化和对环境的影响等作了初步的分析和探索

关键词: 高程信息,冰貌信息,栅格／矢量,数据变换,冰貌图

Abstract:

This paper discusses extract of elevation and ice geomorphologic information from the spectral and spacial feature in Landsat TM image of Antarctica with ARIES digital image processing system,raster vector data transformation and creation of topologic relation between objects. After edited by RAMS processing system, ice geomorphologic map is plotted.At last,forming, distribution, change of ice geomorphology and influence of the change to environment are analysed.
