ABSTRACT
Aerotriangulation by independent model (AIM) was performed on Wild A-7 Autograph using wide angle photographs of average scale of 1,8000. In performing the Aerotriangulation, the relative orientation was carried out by numerical method and the model coordinates of the perspective - centre; employed for the model connections was measured. The research seeks to establish the accuracy of AIM by using different densities and distributions of points for numerical relative orientation and twenty perspective - center determinations. Practical investigation reveals that cases of the same density will produce similar results irrespective of differences in distribution. The accuracy of strip formation was found to be dependent on the distribution and density of points used for numerical relative orientation of the first model. For instance case 1 with only six points has accuracies of � 0.1612 mm in planimetry and � 0.163 mm in height, case 25 with fifteen relative orientation points has accuracies of � 2.933 mm in planimetry and � 0.505 mm in height.
