Using network-RTK for cadastral reform in Republic of Korea
Jongmin Lee, Byeongun Park & Dekkie Tcha
In 2011, National Assembly of South Korea enacted a law dealing with Cadastral System Reform. It is important changes to existing cadastral system which sustained for 100 years from land management system to surveying technology. And central government established general plans that introducing three-dimensional digital Cadastre system, integrated real estate information books and advanced surveying technologies such as aerial photogrammetry and GNSS RTK positioning. Accuracy of GNSS positioning have improved in the last thirty years using various reinforcement method so that the latest navigation satellites allow users to determine true positions to within a few centimeters in real time. One of the main issues in Cadastral Reform is establishing control point network which is integrated triangulation points and bench marks because height information is essential part of future cadastral system. In this paper, we present new 3D cadastral control points model which is able to use for digital map by surveyor. Moreover, we investigate the possibility to using GNSS surveying technology, especially Network-RTK for cadastral reform project in order to acquire 3D positions and improve productivity of surveying tasks.
