Abstract
Tie paper developed the satellite imagery block adjustment.Testing the satellite imagery block adjustment on SPOT-5 HRS imagery in two areas without any GCP,on condition of one strip,the mapping accuracy matches the criteria of 1∶500 000.on condition of two stripes,the accuracy matches the criteria of 1∶50 000;Then testing the satellite imagery block adjustment on SPOT-5 HRS one strip imagery without single GCP,the mapping accuracy matches the criteria of 1:50 000.Thus,the validity of the transformation in image plane plus RPC model has been verified.The results show the potential of using this model for mapping terrain with satellite imagery.
