SAR2Opt: 600x600 SAR and Optical Image Pairs at 1-Meter Resolution

600x600 pixel image pairs of Synthetic Aperture Radar and optical satellite imagery at a spatial resolution of 1 meter. The dataset was created by researchers from umkc-mcc, with SAR images collected by TerraSAR-X between 2007 and 2013. Corresponding optical images were sourced from Google Earth Engine and coregistered manually.

Use Cases

• Train SAR-to-optical image translation models based on the coregistered image pairs.
• Develop data fusion algorithms for remote sensing applications using the paired SAR and optical data.
• Benchmark coregistration or feature matching techniques on the manually aligned satellite imagery.
• Study urban or geographical features across different sensor modalities (SAR vs. optical).

Strengths

• Provides 1-meter spatial resolution imagery, offering high detail for analysis.
• Contains manually coregistered pairs of SAR and optical images, ensuring spatial alignment.
• Covers ten cities across Asia, North America, Oceania, and Europe, offering geographic diversity.
• Uses TerraSAR-X, a well-known satellite platform, for SAR data collection.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect temporal bias inherent to the 2007-2013 collection period.
