摘要:The SPOT system is the first space orbiting satellite withstereoscopic capability. Stereoscopic pairs with variableincidence angles and base to height ratios can be obtained. Theavailability of stereoscopic data from space will enhance theprocess of topographic mapping and maps revision for unmapped orpoorly mapped areas around the world.In this investigation accuracy of stereoscopic informationextracted from a SPOT stereo pair are tested using twophotogrammetric methods. In the first method, a stereoscopicmodel is formed ,analytically. by the conventional procedure ofrelative orientation. Hodel coordinates are fitted into groundcoordinates using three dimensional affine and polynomialstransformations. In the second testing method, groundcoordinates of check points are computed by intersection oforiented rays. This followed the determination of the exteriororientation elements of each individual imagery using the spaceresection equations. Residuals • in check points, and their rootmean square values are computed in each case.
