Management and Utilization of National Control Points for Efficiency of Survey

Outline of Management and Utilization of National Control Points for Efficiency of Survey


National control points provide the foundation of accurate positioning. Lack of control points or lack of proper maintenance of them causes discrepancy of positions of any object between the map and the reality, or between different maps.
Recently, GNSS Continuously Operating Reference Stations (CORS) infrastructure is increasingly being introduced throughout the world to provide the geodetic reference frame. GNSS CORS infrastructure enables precise positioning, and thus promotes that geospatial information supports the sustainable development of the society.
Thus, with aim to share its experience on development and management of GNSS CORS, the Geospatial Information Authority of Japan (GSI), which has more than 20-year of experience in operating the infrastructure in Japan, designs to provide the knowledge on managing national geodetic reference frame tailored for the situation in each country.


Measures to improve the services in terms of national control point management and utilization that suits the situation of each country, for the promotion of the development of geospatial information, are formulated in NGIAs.

Participants are expected to achieve the following outputs;
  1. Develop an understanding on the government’s administration on survey issues and the legislative framework in Japan.
  2. Survey methods utilizing positioning satellites, and those utilizing the continuous GNSS observation system can be explained.
  3. Method to develop geospatial information utilizing the continuous GNSS observation system can be explained.
  4. Method to introduce and utilize the world geodetic system can be explained.
  5. Based on the understanding on the situation of national control point management and the situation of infrastructure development in each country, a proposal on adequate control point management and measures on utilization can be proposed.
