IKONOS: High-Resolution Panchromatic Satellite Imagery

Global land surface imagery was collected by the IKONOS satellite from October 1999 to March 2015. The Level 1B product provides panchromatic data with a spatial resolution of 0.82 meters at nadir and a temporal resolution of approximately 3 days. Access to this high-resolution imagery is restricted to approved investigators under a National Geospatial-Intelligence Agency license.

Use Cases

• Land cover change detection based on the 15-year time series.
• High-resolution mapping and feature extraction based on the 0.82m spatial resolution.
• Sensor calibration and validation for other satellite systems based on the Level 1B sensor-corrected product.

Strengths

• Provides a long-term historical archive with a 15-year collection period.
• Offers high spatial detail with a resolution of 0.82 meters at nadir.
• Data is sensor-corrected (Level 1B), providing a consistent raw product.

Limitations

• Access is heavily restricted by an NGA license and requires program approval.
• Metadata completeness is medium; specific column names and dataset size are not provided.
• The most recent data is from 2015, limiting analysis of recent events.
