Gwangju City to Promote Cadastral Advancement Project by 2025

Gwangju City Hall

[Asia Economy Honam Reporting Headquarters Reporter Park Seon-gang] Gwangju Metropolitan City announced on the 1st that, starting this year, it will promote an advanced project for expanding cadastral control points and improving the management system over five years until 2025, following the full transition of cadastral surveying standards from the regional geodetic system to the global geodetic system.

Until now, in spatial analysis through the fusion of spatial information, the coordinate system of cadastral (land area) data differed, making it difficult to directly overlay and utilize various spatial information such as aerial photographs with cadastral and forest maps.

Once the transition project of cadastral data from the regional geodetic system to the global geodetic system is completed in the first half of this year, it is expected that accurate spatial information fusion will be promptly achieved, laying the foundation for promoting the integrated use of various data containing location information.

Accordingly, Gwangju City will conduct re-surveys of 8,700 cadastral control points that have not been converted to the global geodetic system and newly expand 2,800 points in deficient areas to secure the accuracy of cadastral surveying and protect citizens' property rights.

In addition, to improve the cadastral control point management system, an investigation of all approximately 13,000 points will be conducted, and a cooperative system with related departments such as roads will be established to enable stable maintenance and rapid restoration.

To this end, the functions of the aerial photograph integrated management system have been expanded to build a mobile field survey system, and a working consultative body involving autonomous districts and the Korea Land and Geospatial Informatix Corporation will be formed and operated within this month.

Furthermore, to resolve the side effects where many surveys and maintenance budgets were required annually due to repeated loss and damage of control points caused by road excavation and paving, improvements across the entire management system will be promoted by dividing into three areas: comprehensive investigation, management system, and expansion of the control point network.

Lee Su-won, Director of the Land Information Division of the city, said, “Through this project, we expect to improve the efficiency of cadastral surveying and save about 200 million won annually in management budgets,” and added, “We will continue to expand cadastral control points to provide accurate cadastral surveying services that meet the demands of the digital era.”
