Image Enhancement

Enhancements improve the viewing quality of satellite imagery because the human eye cannot discern as many gray shades as can be displayed in most types of satellite imagery. Enhancements can exaggerate minor shading differences or highlight features of interest. Enhancements available include lightening, darkening, false coloring and contrast stretching the image. For example, infrared (GIF) satellite image, 0030 UTC 28 October 2006:
