BLM Colorado Oil and Gas Lease Parcels for Q1 2026

BLM Colorado's Quarterly Oil and Gas Lease Sale Parcels consist of digital mapping data for the state. The dataset includes polygon geometry generated from legal land descriptions and the Geographic Coordinate Data Base survey grid. Mapped parcels are consolidated from Field Office inputs.

Use Cases

• Analyze polygon geometry to assess the spatial distribution of deferred oil and gas lease parcels in Colorado.
• Cross-reference mapped parcel data with legal land descriptions from sale notices for validation purposes.
• Use the Geographic Coordinate Data Base (GCDB) survey grid to verify the geospatial accuracy of lease parcel boundaries.

Strengths

• Data is sourced from the authoritative Bureau of Land Management (BLM) under the Department of the Interior.
• Polygon geometry is generated using the standardized Geographic Coordinate Data Base (GCDB) survey grid.
• Data is consolidated from multiple BLM Field Office inputs, providing a unified view.

Limitations

• The dataset may contain error files with polygons that failed automated processing, requiring manual verification.
• Data accuracy is dependent on manual completion by BLM GIS specialists for identified error polygons.
• Sample data and specific row/column counts are unavailable, limiting initial assessment of dataset scale and structure.
