Abstract This paper investigates the method of high-precision digital elevation model generation in gravity intermediate area topographic correction with ZY-3 stereo surveying satellite data. The rational function model has been refined with the GPS points and forward, nadir, backward image data. The experimental verification of topographic correction with 1:10 000 high-precision digital elevation model data shows that the digital elevation model produced by ZY-3 stereo data can meet the precision requirement for 1:200 000 gravity intermediate area topographic correction. The result obtained by the authors provides an effective means for gravity intermediate area topographic correction and expands the application of ZY-3 in regional gravity survey.
