摘　　要：该文对遥感影像空间分辨率与成图比例尺的关系进行了研究,提出对应数学表达式。并分别对两种常用的高分辨率遥感影像IKONOS和QUICKBIRD进行了试验,以RTKGPS测量值作为真值,精校正遥感影像与真值的差作为遥感影像的实地误差,计算出影像几何校正系数,从而得到两种分辨率遥感影像可以制作的合理成图比例尺。This paper presents a formula regarding the relationship between spatial resolution of RS image and mapping scale on a study area. The common high resolution RS images, choosing IKONOS and QUICKBIRD as the models in this study, are rectified by certain scale relief map related. Then some reference points in the study area were measured by RTK GPS to get some base points as true value. The difference between the value on the RS image and the RTK GPS value can be used to work out a geometry revised coefficient, divided by the resolution of RS image, which can be used to figure out the mapping scale.
