Maxar Open Data: Pre- and Post-Event High-Resolution Satellite Imagery

Maxar's Open Data Program provides analysis-ready, cloud-optimized satellite imagery for disaster events. The imagery is generated using the Maxar ARD pipeline and tiled on an organized grid. It is hosted on AWS Open Data under a CC-BY-NC-4.0 license.

Use Cases

• Emergency planning based on pre-event high-resolution imagery
• Damage assessment based on pre- and post-event imagery comparison
• Monitoring of staging areas and recovery progress based on time-series imagery
• Risk assessment for infrastructure and communities based on geospatial analysis

Strengths

• Imagery is processed through the Maxar ARD pipeline for analysis-ready quality.
• Data is provided in cloud-optimized GeoTIFF (COG) format for efficient access.
• Imagery is high-resolution, suitable for detailed assessment.

Limitations

• Row count and total dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
