Abstract :
In this paper, 5 schemes of compensation models for Rational Function Model (RFM) is proposed to improve stereo geolocation accuracy of GeoEye-1. And experimentation is carried out using stereo pair of Hobart, Australia. The results show that the accuracy of 5 schemes is similar, and with high accurate and well-distributed Ground Control Points (GCPs) the planimetry and elevation accuracy of GeoEye-1 stereo imagery pairs are both better than 0.5-meter and meet the specification for 1:5,000 topographic map of China.
