KRIHS Invites Japanese GIS Experts for Special Lectures


About: “Analysis and Visualization of Spatial Big Data Using Web-GIS—Person Trip in Mega Cities” and “Analysis on Japanese Watersheds Using GIS and Lattice Data”
Date: March 20, 2015
At: Korea Research Institute for Human Settlements

The Geospatial Information Research Division at Korea Research Institute for Human Settlements (KRIHS) invited Professor Murayama Yuji and Yamashita Akio of University of Tsukuba for special lectures. On March 20, Professor Murayama, the former chair of Japanese GIS Society, gave a lecture on “Analysis and Visualization of Spatial Big Data Using Web-GIS—Person Trip in a Mega City,” and Professor Yamashita’s lecture on “Analysis on Japanese Watersheds Using GIS and Lattice Data” followed. Professor Murayama presented the process of Web-GIS spatial analysis in his lecture: first, he mapped millions of Person Trip Surveys in Tokyo every minute and visualized the analysis outcomes based on the attribute data including the purpose of trips, transport, age, and sex. He also analyzed other Asian mega cities such as Jakarta and Hanoi using the same tool and method—by analyzing how people travel in those cities. Professor Yamashita started his lecture by explaining the lattice data system in Japan and then presented the changes in watershed areas and water supply-and-demand results based on a variety of data obtained from the lattice data. In the Q&A session after the lectures, participants actively expressed interests and shared ideas on PT data utilization. About thirty attendees in and outside KRIHS included Sakong Hosang, the director of the host division of the KRIHS, Official Kang Kyehwa of Statistics Korea, Professor Ryu Jungseok of Chungang University, Professor Ku Jayong of Sangmyung University, and Professor Hong Ilyoung of Namseoul University.
