Panchromatic Sensor

The Panchromatic (PAN) Sensor had 5.8 m spatial resolution, as well as stereo capability. Its swath width is 70 m. Revisit time was every five days, with ± 26° off-nadir viewing.

Panchromatic Imagery

A panchromatic imagery uses a single band image. This imagery is extremely useful, as it is a much higher spatial resolution than the multispectral imagery from the same satellite. For example, the QuickBird satellite produces pan imagery having a pixel equivalent to an area 0.6 m × 0.6 m (2 ft × 2 ft), while the multi-spectral pixels represent an area of 2.4 m × 2.4 m (8 ft × 8 ft).

Color Composites With Panchromatic Band

The process of sharpening color composites with the pan band can be performed using 3 most common of them:

  • HSV (Higher Spatial Resolution) Sharpening
  • Gram-Schmidt Pan-Sharpening
  • The Brovey Transformation
