IKONOS Level 1B: 4-Band Satellite Imagery from 1999 to 2015

IKONOS satellite imagery provides 3.2-meter resolution multispectral data in blue, green, red, and near-infrared wavelengths. The collection spans the global land surface from October 1999 to March 2015, with a revisit time of approximately 3 days. NASA's Commercial Smallsat Data Acquisition Program acquired this sensor-corrected Level 1B imagery from Maxar Technologies.

Use Cases

• Monitor land cover changes over time based on the 15-year global coverage.
• Analyze vegetation health and biomass based on near-infrared wavelength data.
• Perform high-resolution urban planning and infrastructure assessment based on 3.2-meter spatial resolution.
• Conduct environmental impact studies based on multispectral data in visible and near-infrared wavebands.

Strengths

• Spatial resolution of 3.2 meters at nadir provides detailed imagery.
• 15-year temporal coverage from 1999 to 2015 offers a long historical record.
• Data includes four spectral bands (blue, green, red, near-infrared) for multispectral analysis.

Limitations

• Data access is restricted by a National Geospatial-Intelligence Agency license and requires program approval.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
