本文以1: 100万标准分幅的成都幅(H-48)为例,采用SRTM-DEM数据,利用ERDAS软件、MicroDEM软件和Global Mapper软件,进行地貌晕渲图原图的制作,并利用Photoshop软件,对它们生成的地貌晕渲图原图进行了颜色调整、效果优化和与地图底图叠加生成最终的地貌晕渲图.研究表明:(1)利用3种软件进行地貌晕渲图原图的制作各有优缺点,但就最终成果图的整体质量和效果来看,Global Mapper软件制作的地貌晕渲图要优于MicroDEM软件制作的地貌晕渲图,而以ERDAS软件制作的地貌晕渲图的质量和效果最差;(2)Photoshop软件作为强大的图形图像处理软件,可以在地貌晕渲图的效果调整和质量优化上起到重要作用;(3)由于数字环境下地貌晕渲图可以表达更多的信息量和色彩效果,它对于制图人员色彩的运用、表达效果的判断和调整能力等提出了更高的要求和挑战.

Taking Chengdu region (sheet number H-48,national standard division range 1: 1000000 geomorphologic maps) as an example,this paper studies the production method of relief shading maps using software of ERDAS，MicroDEM and Global Mapper,and data source of SRTM-DEM.Then，the relief shading maps are color adjusted,effect optimized Photoshop software.After overlaying the relief shading map and geographical base map,the final relief shading maps are produced.The research shows: (1) Although each production method of relief shading maps has merits and demerits,but as to the results’ quality and effect,the relief shading map made by Global Mapper is better than it made by MicoDEM,and the quality and effect of the relief shading map made by ERDAS are the worst; (2) As a strong image processing software,Photoshop plays an important role in the effect adjustment and quality optimization of relief shading map production; (3) As the relief shading map can represent more information content and better color effect,it puts forward a higher requirement and challenge for cartographer in color use,and in the judgement and adjusting ability for the representing effect.
