Nickel Mining Expansion in Indonesia and Philippines, 2016-2025

Xiaoxin Zhang's dataset maps the spatiotemporal expansion of nickel mining in Indonesia and the Philippines from 2016 to 2025 using high-resolution satellite observations and deep learning. It includes annual mining polygons, 1,500 validation sample locations, and validation matrices. An interactive Google Earth Engine app is provided for visualization.

Use Cases

• Tracking annual changes in mining footprint based on the time-series polygon layers
• Assessing model accuracy for land classification using the 1,500 validation samples
• Visualizing mining expansion patterns via the linked Google Earth Engine application
• Analyzing validation metrics from the provided Excel calculation matrices

Strengths

• Includes a validation set of 1,500 randomly selected samples
• Provides annual data spanning a 10-year time range from 2016 to 2025
• Offers an interactive visualization tool through a Google Earth Engine app

Limitations

• Column names and a precise row count are not provided in the metadata
• The dataset's size is listed but its internal structure is not detailed
