摘要
简述了GIS的数字地形分析与DEM的研究进展,指出了数字高程模型分析3个方向的研究内容,并进一步系统总结了数字高程模型在地貌中的可视化分析、地形因子的提取与地貌的综合分析3个方面中的研究现状,同时列举了大量的研究成果,最后指出了数字高程模型研究的重要意义。
Research development of DEM was summarized, three application directions of DTM were analyzed. Further more, present research situations about DEM in geomorphology analysis such as visualization analysis, terrain analysis and generalized analysis was summarized over all. Some research results in geomorphology analysis were enumerated simultaneously. Important meaning in DEM research was point out finally.
