At the invitation of the International Christian University of Japan, Yu Zhaoyuanof the Nanjing Normal University Institute of Geography and Science 1 people from June 7, 2017 to 10th went to Tokyo, Japan to participate in the lectures on geometric algebra and GIS and the “2017 Symposium on Geometric algebra and its application in computer graphics Conference”, meeting of China-Japan Preparatory Committee. June 8, 2017 Yu Zhaoyuan, a special report on the application of geometric algebra in GIS research, was made at the Forum Advanced Forum at the NS of the Christian University of Japan.Eckhard Hitzer, Faculty of Arts, Materials and engineering sciences, International Christian University, Japan, 5, professor of Japanese Institute of Technology Kanta Tachibana, Japan National Institute of Intelligence, Japanese-French joint laboratory Vincent Professor Nozick and other 2 people, as well as the relevant audience, more than 60 people participated in the lecture.We discussed the content of the lecture, and thought that the new direction of Geo-information application based on geometric algebra has become a new growth point based on the application of geometric algebra engineering.June 8, 2017-9th discussed and voted on the agenda of the “2017 International Computer graphics conference geometric algebra and its Application symposium” at Japan Institute of Technology and Japan National Institute of Information.Determine the “2017 International Computer graphics conference geometric algebra and its calculation application workshop” schedule from the original 1 days to 1 days and a half, and increased the “geometrical space analysis and image processing” theme topics.Accompanied by Professor Vincent Nozick of Japan’s National Institute of Intelligence and the Japanese-French joint laboratory, Yu Zhaoyuan, an associate professor, visited the infrastructure and related research results of the National Institute of Information in Japan, and the geometric algebra in the high-dimensional hierarchy Large-scale network analysis and dynamic emergency evacuation and other aspects of cooperation in a deep discussion.The access has obtained the good result, has laid the good international development environment for the Geographical Information System application new direction based on the geometric algebra.
