IKONOS 4-Band Multispectral Satellite Imagery At 3.2-Meter Resolution

IKONOS satellite imagery provides 3.2-meter resolution data across blue, green, red, and near-infrared wavelengths. The collection contains sensor-corrected, unprojected imagery of the global land surface from October 1999 to March 2015. It was acquired by Maxar Technologies for NASA's Commercial Smallsat Data Acquisition Program.

Use Cases

• Land cover classification using the blue, green, red, and near-infrared spectral bands.
• Change detection analysis over time, leveraging the 3-day temporal resolution and 15-year time range.
• Vegetation health assessment via indices calculated from the red and near-infrared wavelength data.
• Urban feature extraction and mapping, supported by the 3.2-meter spatial resolution at nadir.

Strengths

• 15-year temporal coverage from 1999 to 2015.
• 3.2-meter spatial resolution at nadir for detailed analysis.
• Data available in both NITF and GeoTIFF formats.

Limitations

• Data collection ended in March 2015, limiting analysis of recent events.
• Access is restricted by an NGA license and requires program approval.
