Operate stereoscopic plotting and computer graphics equipment to provide three-dimensional optical models of terrain, to trace maps, and to prepare charts and tables.

All differences between vector data and the aerial images were identified, marked and sent to a photogrammetry team that did the update via stereo-restitution.

For modeling landmarks and complex buildings such as churches, unique skyscrapers, and sports stadiums, Avineon used manual modeling techniques based on their expertise in stereo-restitution.
