Abstracts. — Our experiments of spectrozonal stereophotogram- metry in the Western Alps are related to Spacelab program using a metric camera in the perspective of the first Spacelab flight aboard of NASA Space Shuttle, which will over fly the Alps between 4th and 11 th December 1980. We made aerial and ground photographs of Wallis mountains (Obergabelhorn, Blanc de Morning, Zinalrothorn close to Zinal) and of Dolomiti di Cortina d'Ampezzo (Tre Cime di Lavaredo) in Italy, using spectrozonal emulsions (Kodak S. 0 .410 or classical Ektachrome Infra-Red) and optical multichannels filters. These technics are compatible with European Space Agency and NASA specifications, owners respectively of Spacelab and Space Shuttle: final ground resolution better than 20 meters, with exposure speeds of 1/1000 second at the scale of 1/820.000 on the film, in spite of a ground motion of 7.755,75 meters per second. In that way, several elementary forms of alpine geomorphology (ind ice — or snow phenomena will be detectable on metric scenes of this first industrial survey from space.
