AB: The geodetic datum of Korea is superseded by the new Korean Geodetic Datum 2002 (KGD2002) which is a world geodetic system compliant with the ITRS from January 1, 2007. Based on the new definition of the geodetic datum, the geodetic network in Korea is re-adjusted to provide the new realization of the datum. The readjustment is carried out under the campaign of KGD2002 which the Korean Geographic Information Institute (KGII) was initiated in 1999. In this study, the summarized whole procedure of the network adjustment to realize KGD2002 is explained and described. Starting from the data arrangement in terms of regions and years, the quality check, the readjustment strategies such as local and nationwide adjustments are described in detail. As the result, the nationwide network of the datum focused on the horizontal one with its accuracy is presented. For general readers, a brief history of Korean geodetic network is also included. In addition, the future plans on the management/development of the Korean network are also described. It is expected that this study contributes in datum changes of other countries by providing the expected problems, strategies, and solutions.
