Colorado Oil and Gas Lease Sale Parcels for Q3 2025

BLM Colorado's Quarterly Oil and Gas Lease Sale Parcels consist of digital mapping data describing polygon geometry and linked attributes for the state. The data is generated using legal land descriptions and the Geographic Coordinate Data Base survey grid. It was last consolidated from field office inputs and updated in March 2026.

Use Cases

• Analyze parcel polygon geometry to assess the spatial distribution and size of available lease tracts.
• Map lease parcels using the legal land descriptions and GCDB survey grid for land management planning.
• Validate mapped parcel data against official sale notice documents for regulatory compliance.

Strengths

• Data is sourced from the authoritative Bureau of Land Management, part of the Department of the Interior.
• Polygon geometry is generated from the official Geographic Coordinate Data Base (GCDB) survey grid.
• Data was updated on March 3, 2026, indicating recent maintenance.

Limitations

• The dataset lacks explicit row and column counts, making its scale and feature set unclear.
• Data accuracy depends on field office inputs and requires manual verification against legal descriptions.
• The specific attribute fields linked to the polygons are not documented.
