Ulsan City Selected for High-Precision Electronic Map Construction Project for Third Consecutive Year

Secured 2.7 Billion KRW in National Funding for Urban Data Infrastructure
Digital Twin Ulsan Enters Final Phase of Third-Year Project

Ulsan City has been selected for the third consecutive year for the "2026 National Budget Linked (Matching) High-Precision Electronic Map Construction Challenge Project," organized by the Ministry of Land, Infrastructure and Transport, securing 2.7 billion KRW in national funding.

With this selection, the city expects that the "Digital Twin Ulsan" project, which has been promoted as a three-year plan since 2024, will enter its completion phase.

The core of this project is the production of large-scale (1:1000) digital topographic maps required for data-based administrative tasks and private sector use, as well as the construction of three-dimensional spatial information for urban areas, which is essential for the operation of the digital twin.

In particular, the large-scale (1:1000) digital topographic maps include detailed locations of urban infrastructure elements such as sewage pipes (manholes), streetlights, utility poles, traffic lights, and crosswalks, which were difficult to represent with the existing 1:5000 maps. These maps will be used as key resources for urban planning, social infrastructure design, emergency response, and underground facility management.

Additionally, these maps will be utilized in various location-based services, including domestic and international map portal services, navigation systems, and site analysis, providing citizens with accurate and detailed geographic information.

Ulsan City began the Challenge Project in 2024 with a budget of 3.5 billion KRW, followed by 4 billion KRW in 2025, and 5.4 billion KRW in 2026 (2.7 billion KRW each from national and city funds), investing a total of 12.9 billion KRW over three years to update the electronic maps of the entire Ulsan area through the "Digital Twin Ulsan" project.

In particular, advanced technologies such as aerial and drone photography, LiDAR, Mobile Mapping System (MMS), and hyperspectral imaging are being used in the Banggucheon and Taehwagang areas, as well as development-restricted zones, to build foundational spatial information, including the Taehwagang ecological river topographic map, carbon spatial map, precision road map, and 3D models of buildings and trees.

Based on these efforts, the city plans to establish a data foundation that can be used for urban flood prediction, climate crisis response, autonomous driving and urban air mobility (UAM) route planning, and preparations for the Ulsan International Garden Expo.

An Ulsan City official stated, "We will do our utmost to promote this project so that we can establish a system to scientifically solve various urban problems based on precise spatial information, thereby enhancing citizen convenience and the quality of administrative services."
