Multispectral data

Multispectral data

Multispectral data refers to information collected across multiple specific wavelength bands of the electromagnetic spectrum. Unlike single-band (or monochromatic) data, which captures information in just one part of the spectrum, multispectral data captures information in several distinct bands, each corresponding to a different range of wavelengths. 

Wavelength Bands: 

Multispectral data is collected across several predetermined bands, which can include visible light, near infrared, and shortwave infrared. Each band captures different spectral information that can be used to identify various materials and features. 

Examples of Bands: 

• Visible Bands: Red, green, and blue bands for colour imaging. 

• Near-Infrared (NIR): Useful for assessing vegetation health and water bodies. 

• Shortwave Infrared (SWIR): Useful for distinguishing between different minerals and soil types.
