Photogrammetric evaluation of Mariner 9 photography

Some attempts to produce, with an AP/C analytical plotter, stereo models using Mariner 9 pictures are reported. The first attempt using geometrically uncorrected mission test video system (MTVS) imagery failed; the second, using corrected reduced data record (RDR) pictures also failed, probably because they were reconstructed through a vidicon display which introduces additional distortion. By using images obtained from RDR tape data through the Optronics Photowrite device, models were successfully obtained.
