Paper Abstract

This paper presents the research activity of the French National Geographic Institute (IGN) in the field of digital photogrammetry. Focusing on aerial stereo pairs analysis, IGN research policy was set up in 1990 in the specific context of the production of a topographic database on the whole national territory. Stress was given to four major applications: contour line generation from automatic correlation techniques, road semi-automatic plotting, 3D building extraction, and map analysis. This latter topic actually started in 1994. The other three ones were undertaken in 1991 within a four people team, that was to grow up to 15 in 1995. Nowadays, IGN come to a key point of this activity, first because the primary results of the research are reaching enough maturity to foresee possible operational use, and secondly because the production lines are now evolving toward the digital stereoplotter technology.
