Automatic Aerial Triangulation Software Of Z/I Imaging

Results of the OEEPE-ISPRS test on performance of automatic tie point extraction in the existing Automatic Aerial Triangulation (AAT) have shown limitations as well as potential for improvements in todays AAT solutions. Z/I Imaging as a photogrammetry system provider, has decided to improve its existing, well known PHODIS AT product by integrating it into the Windows NT based ImageStation platform and in the meantime to enhance its functionality to address the limitations of the existing AAT solution. This paper introduces some of the main features of the newly developed ImageStation Automatic Aerial Triangulation (ISAT) product. The new technology AAT system is shown as an expanded system to improve the conventional AAT approach to handle GPS/INS data in an optimized way as well as to overcome current drawbacks in tie point determination.
