What Is a Multiband Scanner?
A multi-band scan image is an image acquired by a multi-band scanner (MSS). Obtained by air or space remote sensing. It is an important imaging method for satellite remote sensing.

- A multi-band scan image is an image acquired by a multi-band scanner (MSS). Obtained by air or space remote sensing. It is an important imaging method for satellite remote sensing.
- Its main features are: The image is continuous strip-shaped. The image pixels are continuous on the scan line, and discontinuous between the scan line rows. Image spatial resolution (depending on the instantaneous field of view and altitude) and sharpness are not as good as visible light imaging under the same conditions; The geometric relationship of the image is multi-center projection. Because imaging under dynamic scanning conditions, the geometric fidelity of the image is greatly affected by the attitude change of the remote sensing platform, especially for aerial multi-band scanning images, so the distortion is large and the correction is difficult; with multi-band. The number of bands is up to 24 depending on the number of sensor channels. Visible and near-infrared bands are commonly used. The image is rich in information, and any of 2 to 4 bands can be used for color synthesis to obtain a variety of false color images, which is flexible in application; tape recording for easy playback into analog images or direct use for digital image processing and computer-aided automatic classification. Multi-band scanning image is the main way to acquire multi-band data of ground objects in space remote sensing.
