ABSTRACT:

This presentation concerns a new process for aerial photo interpreters that treats digital imagery as if it were analog, for stereo viewing purposes. As the photographic industry has been undergoing the transition from chemical/analog reproduction to digital-only reproduction, photo interpretation has become increasingly difficult to perform.  Traditional zoom stereoscopes are quickly becoming an untenable solution due to a lack of available film-based reproductions.  Achieving comparable results using stereoscopes with paper prints can require purchasing multiple enlargements or consuming more time by printing self-made enlargements.  Using digital imagery directly has been impossible without costly and/or cumbersome equipment.  All this has changed with the advent of relatively cost-effective 4K monitors and a new patent-pending process for manipulating digital imagery combining a conventional lens stereoscope, a 4K monitor, and image viewing software.  It allows stereoscopic photo interpretation of historical aerial photography to be performed purely digitally.  This new digital process closely matches the traditional zoom stereoscope method.
