NSUOTRACE is an environmental intelligence platform that detects illegal gold mining (galamsey) in Ghana's Amansie headwaters from satellite imagery. Galamsey devastates rivers, farmland, and community water sources, yet monitoring is manual, sparse, and slow — by the time damage is confirmed on the ground, it has spread. NSUOTRACE gives regulators and community monitors two capabilities in one dark, map-first interface: (1) on-demand AI scanning — draw any area inside the imagery coverage and run the Exp14 UNet++ mining detector or the CVA landscape-change engine, with results as visual intelligence reports (conclusion, stat cards, map outlines, per-region satellite evidence with AI overlays); (2) proactive monitoring — 601 automatically flagged historical anomalies from 2021–2025 surveys, ordered Investigate First with transparent triage criteria. A River Intelligence workspace links land disturbance to 14 real stream measurement points along a 6.75 km reach (satellite-derived turbidity indicators, honest about uncertainty), 36 verification cases carry human verdicts, and an AI Laboratory documents methods and limitations — including a failed self-supervised experiment we report honestly instead of hiding. Every claim is evidence-first: real imagery, real coordinates, no fabricated detections.
