Remote sensing technology, through revolutionary advancements in satellite imagery, is fundamentally transforming North Korean studies. Multi-layered analysis capabilities through optical, thermal band, and radar satellite imagery now enable precise observations of environmental changes, land use transitions, urbanization patterns, economic disparities, and structural transformations. The New Space era, with enhanced commercial satellite capabilities and sophisticated AI-based analytics, has established an unprecedented framework for empirically understanding this closed nation. These breakthroughs yield substantial results across domains, including the surveillance of logistics movements through customs, ports, and railway hubs; scrutiny of developmental patterns in major urban centers such as Pyongyang, Kaesong, and Rason; and evaluation of forest restoration policy efficacy. While technical limitations persist regarding data accuracy and algorithmic reliability, the integration of multi-sensor data and refined analytical techniques offers solutions. With continued technological advancement and international collaboration, remote sensing is poised to serve as a pivotal instrument in enhancing North Korean research, contributing significantly to economic planning, environmental management, and policy formulation.
