Gwangju City to Promote Digital Terrain Map Renewal Project... Targeting 53.5㎢ in 33 Districts

[Asia Economy Honam Reporting Headquarters Reporter Park Seon-gang] Gwangju Metropolitan City announced on the 23rd that it will promote the ‘2021 1/1000 Digital Topographic Map Revision and Renewal Project’ to upgrade the changed urban terrain and landmark information to the latest data.

The digital topographic map is an electronic map that expresses various spatial information such as locations on the ground, terrain, buildings, and roads using aerial photogrammetry technology, represented by shapes, symbols, and attributes according to a certain scale.

Since 2007, Gwangju City has been jointly conducting the project with the National Geographic Information Institute, dividing the entire area into seven zones based on characteristics such as areas with discrepancies in terrain and landmarks and areas with outdated production years.

So far, a total of 11.4 billion KRW has been invested to update spatial information for a total area of 754.4㎢.

This year, the city will spend 1 billion KRW to renew 53.5㎢ covering 33 neighborhoods in the urban area (Suwan-Sangmu zone), including Suwan-dong, Chipyeong-dong, and Geumho-dong, which have not been updated for a long time since their initial production.

The latest digital topographic maps updated through the annual renewal project are provided free of charge to citizens via the National Land Information Platform website.

Gwangju City widely utilizes spatial information combined with underground facility data such as water supply and sewage, gas, and communication pipelines as basic data for various administrative tasks including urban planning, roads, traffic, regional development, architecture, firefighting, and disaster management.

Lee Su-won, Director of the Land Information Division of the city, said, “We ask for active cooperation when surveyors visit for on-site geographical surveys related to the digital topographic map renewal,” and added, “We plan to provide the latest spatial information services to citizens through continuous annual updates.”
