IKONOS bands.

• Panchromatic: 0.45–0.90 µm, 1 m resolution.
• Four multispectral bands at 4 m resolution:
  • Blue 0.45–0.52 µm
  • Green 0.51–0.60 µm
  • Red 0.63–0.70 µm
  • NIR 0.76–0.85 µm

• Radiometric resolution: 11 bits → 2 048 grey levels (vs. 8-bit = 256 on SPOT/Landsat TM). This extra bit depth captures subtle contrast in shadows and bright snow/clouds.

• Pan-sharpening of the 4 m MS onto the 1 m pan gives an effective 1 m color image.
