Go to Japanese Homepage
Geospatial Information Authority of Japan(GSI) has established GNSS-based control stations throughout the country. About 1,300 control points have been set up as of today, and are distributed at an interval of about 20km. They are used for surveying, researches for earthquakes and volcanic eruptions. These points enable us to monitor crustal movement in real time.
