On November 8, the International Mangrove Center (IMC) officially released the 2025 IMC Mangrove Atlas 3m（IMA-3m）at the Aerospace Symposium on Data Technology and Data Curation (DTDC 2026). Developed by the IMC Remote Sensing Working Group, the dataset was also published on a national-level data platform — the National Earth Observation Science Data Center. With a spatial resolution of 3 meters, the dataset provides high-resolution mapping of approximately 2.78 million hectares of mangroves across 16 signatory States, establishing a consistent spatial baseline to support long-term mangrove monitoring, conservation, restoration, and resource management.
