Japanese Geodetic Datum 2011 (JGD2011)
In October 2011, GSI released "Japanese Geodetic Datum 2011 (JGD2011)" as the new standard datum of Japan because of the wide area crustal deformation caused by "The 2011 off the Pacific coast of Tohoku Earthquake" which occurred on March 11, 2011. The parameter file and the software for transforming coordinates from JGD2000 to JGD2011 are available from our Public Survey page (in Japanese).
