Weighing 600 Million Buildings Reveals Global Urban Material Inequality and Efficiency Paths

Version 4 adds a README file containing detailed guidance on:

• downloading and reconstructing the File Geodatabase;
• opening the data in ArcGIS Pro, QGIS, and Python;
• interpreting the fields, units, and total_weight values;
• appropriate data uses and important limitations;
• licensing, attribution, and citation; and
• troubleshooting common access and memory issues.

No changes were made to the underlying geodatabase data relative to version 3; version 4 adds documentation only. Users should consult the README before analyzing or reusing the dataset.
