摘　　要：针对境外勘查项目普遍缺少地形图的问题,利用免费的30米采样间隔的数字地面高程模型数据,采用遥感和gis技术,进行了地形图制作的研究。通过此次试验总结出一套可操作性强、易于理解的地形图制作流程,同时降低了开展地质找矿勘查工作的成本,尤其对无人地区和境外地区勘查工作具有较大的现实意义和经济效益。According to the general lack of topographic map in overseas exploration, this paper formed terrain contour using free 30 meters sampling interval digital elevation model data, then mapped the geography based on RS&GIS. Through this test, summed up a set of strong operability, accessible topographic map production process, and reduces the cost of geological prospecting work,the work has great practical significance and economic benefits especially in the exclusion area and Overseas exploration.
