1. entomology to encircle a tree stem with a band of any material such as grease or pesticide that protects it against the passage of insects —note occasionally, bandings such as burlap bands are used to create shelters in which insects aggregate and are useful in estimating population density 2. GIS a wavelength interval in the electromagnetic spectrum —note in digital images, the bands designate specific wavelength intervals at which images are acquired, e.g., C band (6 cm) and L band (23 cm) 3. GIS user-specified wavelength values derived by manipulation of original image bands —note 1. a standard color display of multispectral image has three bands, one each for red, green, and blue —note 2. satellite imagery such as Landsat™ and SPOT provide multispectral images of the earth, some containing seven or more bands 4. range management any number of sheep handled as a unit attended by a herder —see band day 5. wildlife to mark wildlife for studying their movement and other behavior This definition last updated 10/24/2008
