摘　　要：为了研究高分辨遥感影像在地形图修测中的适应情况,选取地势平坦、地物密集的辽工大校区作为试验区,采用Quick Bird的全色和多光谱融合遥感影像为实验对象,利用最新的1:500地形图选取地面控制点(GCP),采用多项式模型进行纠正,对纠正后的影像进行矢量数据采集,通过与原有的矢量图进行比较和定性定量的误差评价。结果证明如利用Quick Bird高分辨率影像最大可以满足1:2000的地形图平面精度要求,因此可采用高分辨率影像对城市基础地理信息数据进行实时更新。In order to make researches on high-resolution remote sensing image for resurveying the map,we make using of Quick Bird satellite image and the experimentation section of the campus of Liaoning Technical University with flat topography and dense nature,and then adopt panchromatic and multispectral products by merging resolution.The image is corrected with polynomial model through the last relief map with the scale of 1：500 to collecte the ground control points（GCPS）.The processed image’s plane absolute error is less than 0.5 meter.The vector graph is updated by using the processed image,and then the precision report is given compared with the old vector map.The absolute precision of single point meets the demand of 1：2000 relief maps.This research can be used for urban basic geographic information data updating with high-resolution image.
