BSQ  

DEFINITION

  • Band sequential (BSQ) is one of three primary methods for encoding image data for multiband raster images in the geospatial domain, such as images obtained from satellites. BSQ is not in itself an image format, but is a method for encoding the actual pixel values of an image in a file. BSQ format is a very simple format, where each line of the data is followed immediately by the next line in the same spectral band. This format is optimal for spatial (x,y) access of any part of a single spectral band. The BSQ data organization can handle any number of bands, and thus accommodates black and white, grayscale, pseudocolor, true color, and multi-spectral image data. Additional information is needed to interpret the image data, such as the numbers of rows, columns, and bands, and relate the image to geospatial locations. This information may be supplied in a file header (typical on the tapes originally used for satellite image data) or in files associated with a raw image data file.
