摘　　要：研究目的:确定莱索托地区北京一号全色影像几何校正方法。研究方法:基于线阵推扫式模型和投影变换模型的几何校正方法,采用真实的莱索托境内平地、高山地两景北京一号全色影像进行试验。研究结果:基于投影变换模型的莱索托地区北京一号全色影像几何校正方法比基于线阵推扫式模型的几何校正方法具有相当或更高的精度。研究结论:投影变换模型可用于莱索托地区土地利用遥感影像图的制作。The covenng Kingd purpose of this paper is to find a suitable geometric correction method for the B J-1 panchromatic image om of Lesotho. The methods used include two geo-correction experiments based on the pushbroom model and the projective transform model for B J-1 small satellite real panchromatic image, covering flat and mountain area of Lesotho. Results show that the projective transform model has equal or even higher accuracy compared to the pushbroom model. Conclusion is that the projective transform model can be used in producing land use image map.
