On Geometric Correction Method of BJ-1 Panchromatic Image Covering Kingdom of Lesotho

摘要

The purpose is to find a suitable geometric correction method of BJ-1 panchromatic image covering Kingdom of Lesotho.The methods are carrying out two geo-correction experiments based on the push-broom model and the projective transform model for BJ-1 small satellite real panchromatic covering flat and mountain area of Lesotho.Results show that the projective transform model has equal or higher accuracy compared to the push-broom model.Conclusion is the projective transform model can be used in producing land use image map.
