A Perceptible Difference

摘要

In September I attended 'From Imagery to Map', a conference organised by Racurs. Founded in 1993 by four research graduates from Moscow Institute of Physics and Technology, this Russian company began as a developer of Photomod, aiming at data extraction from airborne stereo-imagery. Today the software can deal with all types of digital imagery: air or space-borne, optical or microwave, line or array camera. Below, a few noteworthy observations that lie beyond the scope of the conference report on page 37.
