Int. Symposium on Environmental Change and GIS.
Issued on August 23, 1991 (Heisei 3)
In August 1991, the "World Conference on Environmental Change and Geographic Information Systems" was held in Hokkaido. Geographic information system (GIS) analyzes and manages geographic data measured by artificial satellites and ground, and utilizes it as necessary information for daily life. At this conference, GIS geographers and engineers, as well as environmental scientists, presented research and exchanged information on the relationship between human activities and the environment, and the mechanisms and effects of environmental changes.
The stamp was issued in commemoration of this conference, and a "digitized map of Hokkaido" was designed.
