Incheon City Conducts Shared Property Survey Using Drones...Improving Accuracy and Reducing Budget

Public Property Drone Survey Case [Provided by Incheon City]

[Asia Economy Reporter Park Hyesook] Incheon City is set to conduct a survey on public property using drones (UAVs).

The survey targets a total of 30,304 parcels of city public property. Initially, a detailed survey using drone surveying will be conducted on 92 parcels of public property under consideration for sale (across 8 districts and counties, covering an area of 6,378㎡).

Drones are one of the core technologies of the 4th Industrial Revolution era and their utilization is increasing in the field of public administration. When public property is surveyed using drones, accuracy comparable to cadastral surveying can be secured.

Until now, cadastral records were created using a regional geodetic system, making it impossible to link or utilize other spatial information such as drone imagery. However, starting this year, a full implementation of the global geodetic system conversion project for cadastral records is planned. Once cadastral maps are converted to the global geodetic system, drone surveying of public property using drones and GPS satellites will become possible.

The global geodetic system conversion means changing the location reference of cadastral records from the 'regional coordinate system' based on Japan's Tokyo Datum to the 'global geodetic system' which is internationally recognized.

Currently, cadastral records have used the regional geodetic system based on Japan's Tokyo Datum since the land survey project in 1910. This system was set to fit Japanese topography, making it difficult to link and utilize with other spatial information.

However, with the upcoming ability to conduct drone surveying in the public property sector, it will be possible to discover omitted public properties, crack down on illegal occupation, precisely calculate leased areas, reduce cadastral surveying, and thereby achieve strengthened property management measures, increased non-tax revenue, and budget savings.

An official from Incheon City stated, "Drone surveying can improve the accuracy of public property surveys and significantly reduce time and costs. Especially since it is highly effective in confirming unauthorized occupation of public property, we plan to gradually expand its use."
