摘　　要：基于广东省龙川县地形图,探讨应用ArcGIS数字化工具ArcScan对龙川县地形图的数字化方法,结合县域遥感图像实现了地形地物三维可视化,并将其与R2V等专业数字化软件进行了比较。结果表明,使用ArcGIS进行地图数字化的效果较好,即保障数据质量,又提高了数字化的效率和准确性,并可快速实现基于遥感图像的地形图三维可视化。Based on terrain map of Longchuan county in Guangdong province ,a method is showed in this paper to digitalize the county terrain map by ArcScan in ArcGIS software and the course of 3D visualization by RS imagine. In addition, the result was compared with that of the professional digitalizing software-R2V. It indicated that ArcGIS was a good choice to digitalize map with high quality, efficiency and accuracy of data, and quickly to realize 3D visualization of terrain map based on RS imagine.
