Abstract: This paper provides the so-called method "equivalent frame photograph (EFP)" for bundle adjustment from space using three line scanner imagery. The tie points from the CCD images which coordinates have to be transferred to the EFP. The conventional collinear equations and smooth condition about the exterior orientation elements are selected as the mathematical model for adjustment. Some adjustment results using simulated data are made. Finally the possibilities for topographic mapping with contour interval 20m are discussed.
