Nickel mining areas in Indonesia and the Philippines

We combined high-resolution satellite observations from NIFCI with deep learning to monitor the spatiotemporal expansion of nickel mining in Indonesia and the Philippines from 2016 to 2025. The mining layer was evaluated with 1,500 randomly selected validation samples. This collection includes:
