摘　　要：介绍了应用遥感影像更新编绘1∶2.5万地质地理底图的方法,该方法主要是以现有出版的地形图资料为基础资料、近期遥感影像为主要更新资料对地质地理底图进行更新编绘。实践证明,该方法不仅能满足各种野外地质调查工作对地理地图的需要,而且能提高野外地质工作的效率和质量,满足地质找矿要求,是一种现势性强、高效、低成本、准确可行的技术方法。This article introduces a method to update and compile 1 ： 25 000 geographic base map. This method is based on the available published maps and remote sensing image. It is proved that the method can completely satisfy the request of geological survey, enhance efficiency and quality, in the field work, and satisfy the needs of prospecting. In conclusion, it is a highly effective, low-cost, accurate and feasible method.
