| Abstract: | Extraction of accurate spatial information from high-resolution satellite imagery is becoming increasingly important for a variety of tasks. In this study, three-dimensional architectural data were extracted from QuickBird images using Barista’s monoplotting function. We evaluated the accuracy of the Rational Polynomial Coefficients bundle adjustment and extracted building heights. We obtained accuracies of one-pixel in geo-positioning and 2.66 m in building height. The height accuracy is 0.16 m greater than the estimated error for a one-pixel image measurement. The presence of roof overhangs is one primary factors affecting height accuracy. The application of three-dimensional architectural data represents well the vertical extension of urban growth in Tiexi District from 2002 to 2008. |
