Recent analysis of satellite imagery of Wonsan, North Korea, using artificial intelligence reveals rapid progress on large-scale construction projects spanning from the south of Wonsan Airfield to the Kalma Coastal Tourist Zone. Comparing imagery from mid-February, a period of just three weeks, shows that groundwork for the doubling of railway tracks has been completed. Furthermore, new road construction and expansion leading to the entrance of the tourist zones at the southern end of the airfield are actively underway.
