**IKONOS key parameters — bands and radiometry.** | Band | Wavelength (µm) | Resolution | |---|---|---| | Panchromatic | 0.45 – 0.90 | **1 m** | | 1 — Blue | 0.45 – 0.52 | 4 m | | 2 — Green | 0.52 – 0.60 | 4 m | | 3 — Red | 0.63 – 0.69 | 4 m | | 4 — NIR | 0.76 – 0.90 | 4 m | - **Pan-sharpening:** the 4 m MS can be fused with the 1 m pan to yield an effective **1 m color** image. - **Radiometric resolution:** **11-bit** sensitivity → **2 048 grey levels**. Delivered in **16-bit unsigned** data format (the extra 5 bits are zero-padded). - **Temporal resolution:** **~3 days** revisit at mid-latitudes via ±45° off-nadir pointing.
