Yongin City Completes Conversion of 310,000 Parcels of Cadastral Records to World Geodetic System

[Suwon Ilbo=Park No-hun] Yongin City announced on the 28th that it has completed the conversion of approximately 310,000 parcels of cadastral records in the city to the 'World Geodetic System,' which is used as a global standard.

Until now, the city had used a local geodetic system based on Japan's Tokyo meridian that has been in use since 1910 during the Japanese colonial period. This system had a discrepancy of approximately 365 meters from the World Geodetic System, making it difficult to integrate with other spatial information.

In response, the city began converting to the World Geodetic System from July 2013 and completed the geodetic coordinate conversion for all parcels in the city after eight years. Specifically, there are 252,640 parcels in Cheoyin-gu, 41,293 parcels in Giheung-gu, and 22,710 parcels in Suji-gu.

The city plans to complete the World Geodetic System conversion for boundary point coordinate areas by the end of this year and apply it to all records.

As a result, topographic maps, nautical charts, and military maps that use the World Geodetic System, which were revised in 2010, will be compatible with various spatial information data.

A city official stated, "Through the World Geodetic System conversion, we have eliminated remnants of Japanese colonial rule and established a foundation for providing high-quality spatial information to citizens."
