Title: Computational Maintenance on the Official Coordinates Revision in the Korean Triangulation Stations

But, most of the triangulation points, were destroyed during the Korean War, was re-established or re-arranged. The National Geography Institute(NGI) is now executing primary and secondary precise control survey projects with Electronic Distance Measuring equipments, which have average side lengths of 10 Km/2.5 Km. In this study, the revision method of the official coordinates is proposed that the combination of the primary and secondary precise control network is appropriate to new densification adjustments based on the computational schems of the original triangulation framework. And, the redefinition systems of Korean Datum is are also proposed in future networks.Read More
