Sentinel-1 InSAR Surface Deformation over the Permian Basin

Sentinel-1 satellite data reveals surface deformation across an 80,000 square kilometer oil-producing region between 2014 and 2019. The dataset provides cumulative line-of-sight deformation maps at 120-meter pixel spacing for three time intervals, with an uncertainty of approximately 1 centimeter. It includes GPS station locations and digital elevation models for validation and further geospatial analysis.

Use Cases

• Monitoring land subsidence and uplift associated with oil and gas production based on cumulative deformation maps.
• Validating InSAR-derived deformation measurements using provided GPS station location data.
• Analyzing temporal patterns of surface change across three distinct time intervals (2014-2017, 2014-2018, 2014-2019).
• Integrating deformation data with digital elevation models for topographic correction and 3D analysis.

Strengths

• Covers a large, 80,000 square kilometer area of the Permian Basin.
• Provides deformation data with high spatial resolution (120-meter pixel spacing) and low uncertainty (~1 cm).
• Includes data from two satellite paths (ascending 78 and descending 85) for multi-perspective analysis.
• Contains validation data with GPS station locations and time series references.

Limitations

• Metadata completeness is medium; specific column names, row counts, and file sizes are not provided.
• The dataset's last known update was in March 2024, but the core observation period ended in January 2019.
• Platform sources list conflicting or incomplete license information (Open Access (green) vs. None).
