ACCURACY EVALUATION OF GROUND POINTS FROM IKONOS HIGH-RESOLUTION SATELLITE IMAGERY
To evaluate the geometric accuracy of ground points from integrated Global Positioning System, inertial navigation system, and high-resolution linear array CCD sensor data, this paper presents a mathematical model of the bundle adjustment and the experimental results on the attainable accuracy of ground points vs. number and distribution of ground control points (GCPs), vs. the image measurement error of GCPs and checkpoints, and vs. the order of the polynomial fit to the orbital path. A geodetic control network established in Madison County (Ohio), used to test the 3-D accuracy of the simulated new generation IKONOS high-resolution satellite imagery, is introduced. Based on the airborne High Resolution Stereo Camera system and simulated IKONOS imagery, various experimental schemes involving geometric strength with various configurations of stereo models, the influence of the number and distribution of GCPs, and the influence of the image measurement errors of GCPs and checkpoints were performed. Some recommendations and suggestions to improve the geometric accuracy of ground points are provided.
