"Earth Observation Fair '97" was held September 19-20, 1997 at Tokyo Big Sight (Ariake, Koto-ku, Tokyo.) The fair consisted of three parts: a lecture meeting, an exhibition, and an Earth observation data processing training session. The fair was open to the public, and about three thousand people attended. The lecture meeting had a keynote address "Archaeology from Space" and 14 lectures on Earth observation data potential in many scientific fields and general public applications. These lectures presented new information based on the data from ADEOS. Many attendees took notes during these interesting lectures. The exhibition consisted of four poster sessions by remote sensing laboratories and 24 booths exhibits by companies engaged in earth observation and remote sensing activities. Many visitors enjoyed viewing these booths, satellite models and rocket models and talking with exhibitors about interesting displays. In the Earth observation data processing training session, Teachers of junior and senior high schools were given the opportunity to try processing satellite data. The 37 teachers tried to process the satellite data for use in their own classes. After this fair, NASDA plans to execute many projects to promote using Earth observation satellite data in many fields.
