Abstract

Remote Sensing and Geographic Information Systems for High-Precision Municipal Digital Twin Mapping in Korea

Gi-Woong Jo*

  Urban digital twin development increasingly depends on authoritative, updateable, and interoperable geospatial data infrastructure. In South Korea, high-precision digital maps have often been discussed in relation to road-centered high-definition maps for autonomous driving. This study shifts the focus toward local government requirements for land administration, urban planning, disaster and safety management, environmental monitoring, public asset management, and service delivery. Using documentary analysis and structured coding of official policy and program documents from the national geographic information institute high-precision digital map challenge program, the study conceptualizes these requirements through four dimensions: 1:1,000 base mapping, three-dimensional expansion, updating systems, and servitization. The 2024 cases show that base mapping remains a common foundation, while local requirements extend toward three-dimensional city models, elevation and surface-height data, change-detection-based updating, geospatial artificial intelligence-supported updating, cloud-based platforms, and public-facing or administrative services. The findings do not demonstrate administrative performance effects; rather, they show how local requirements are structured around operational fitness, timeliness, interoperability, and service readiness. The study proposes evaluation criteria for mapping programs that seek to move from accuracycentered production toward operational geospatial infrastructure for urban digital twins.
