文章针对当前我国1:5和1:1万地形图更新的大规模生产的迫切需求，提出在原有地形图栅格式数字化的基础上，叠加经过精密纠正配准的航空或卫星遥感影像，以栅格方式更新地物要素的全过程方法。文中特别阐述了：1）地形图栅格数字化不同于矢量数字化的扫描采样分辨率问题；2）区别于传统的“针孔式”控制点概念的图像图形阵列控制点技术；3）由于DEM（数字高程模型）数据缺乏或精度不足引起的航空航天影像与地形图图形配准误差的局部纠正方法；4）定性指导定量的影像判读方法；5）从遥感影像提取地物结构信息的半自动化方法。文章最后列出

To meet the urgent needs of updating 1：10 000 scale and 1 ：50 000 scale topographic map for the whole territory of China, an integrated techinique for key elements revision is proposed, in which the topographic map is updated in raster mode through overlaying the precisely geo-rectified aerial or satellite image on the digitized map. The following issues are specially presented： 1) The scanning resolution of topographic map digitization in raster mode, which is not the same as the one in vector mode. 2) The concept of image array and graphic control point, instead of traditional pinpoint control point. 3) A local registration and adjustment method for rectifying aerial and space image using DRG without DEM. 4) Quantitative image interpretation by the guide of qualitative analysis. 5) The semi-automatic metrod for extraction of structural information from remote sensing image. Finally, a software developed on the basis of the proposed technique and its function are described, at the same time, an experiment result of 600 scenes of 1-50 000 scale topographic maps revision using the developed softwarte is presented.
