MGN V RADAR C3-MIDRs: Magellan Venus Radar Mosaics at 2.025 km Resolution

NASA's Magellan Compressed Thrice Mosaicked Image Data Records (C3-MIDRs) are derived from radar imagery of Venus. The dataset consists of mosaics generated by computing 3x3 pixel arithmetic moving averages from higher-resolution C2-MIDRs, with each mosaic in a sinusoidal equal area projection. Each C1-MIDR source file has 7168 lines and 8192 samples, arranged as 56 1024 x 1024 VICAR2 format files on CD-ROM.

Use Cases

• Planetary surface analysis based on global radar mosaics.
• Signal-to-noise ratio enhancement studies based on the 3x3 pixel averaging process.
• Geospatial projection testing based on the sinusoidal equal area format.
• Comparative planetary geology based on high-resolution global coverage.

Strengths

• Data originates from NASA's authoritative Magellan mission.
• Mosaics are designed for high signal-to-noise ratio and reasonably high resolution with 2.025 km pixel widths.
• Data includes embedded VICAR2 labels, documentation, and summary tabular information.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is stored in a legacy VICAR2 format on CD-ROM, which may require specialized tools for access.
