Global Mining Areas, Modernized

21,060 mining polygons covering 57,278 km² worldwide, representing the physical land footprint of mining activity — open-pit/open-cut areas, tailings dams, waste-rock dumps, water ponds, processing infrastructure, and other directly associated mining land use. Modernized from Maus et al. (2020)'s PANGAEA release into NORA's standardized schema. No new footprint delineation or reinterpretation is performed — attributes and geometries are preserved as published; only field names and container format are modernized.

Why This Dataset Matters

Where is the physical footprint of mining activity? (as opposed to a mineral-occurrence dataset, which answers where a deposit has been recorded). That makes it useful for:

—Mining GIS
—Environmental impact assessment
—Land-use analysis
—Mine footprint mapping
—Mine-area statistics
—Remote-sensing validation
—Environmental monitoring
—Mining-region analysis
—Mineral-resource intelligence
—Spatial joins with geology and geophysics
—Geoscience AI/ML workflows

It can also be integrated with NORA's existing geological, tectonic, geophysical, mineral-occurrence, and environmental datasets to build richer spatial relationships.

Important Limitation

This is not a complete global inventory of every mine. The source dataset was constructed around mines reported as active at some point between 2000 and 2017, and the original authors explicitly state that it does not cover all existing mining locations worldwide. Treat this as a footprint map of the sites that were identified and mapped, not an exhaustive census.

—geoparquet/global_mining_areas.parquet — primary format, mining polygons (EPSG:4326)
—other_formats/global_mining_areas.geojson — secondary format
—other_formats/global_mining_areas.gpkg — secondary format
—metadata.json — provenance, citation, schema dictionary, license

Note: The source archive also includes validation points, a country-level area summary (CSV), and grid rasters at 30 arc-second, 5 arc-minute, and 30 arc-minute resolution. This run modernizes only the primary mining-polygons layer per NORA's standardized schema.
