FAQ
BSQ to PGM Conversion
What are BSQ files?
BSQ is a raw binary raster format developed by ESRI to store multi-band geospatial data, such as multispectral satellite imagery, aerial photography, and thematic surface classifications. As an uncompressed layout where data is organized sequentially by entire spectral bands—writing the full spatial matrix of the first band before starting the second—a file of this type contains no internal metadata, georeferencing, or projection tags. To function properly within a geographic information system, a BSQ file requires a mandatory plain-text sidecar file with a .hdr extension that explicitly defines structural parameters like row and column counts, band numbers, and data types. This format is typically accompanied by other sibling files, including .bsw for spatial world coordinates and .prj for the map projection.
What are PGM files?
The PGM or Portable Graymap format is part of a package of open source graphics programs called Netpbm. Other Netpbm formats include PPM (Portable Pixmap) and PBM (Portable Bitmap), also known under the collective name of PNM (Portable Anymap). A PGM file includes a grayscale image, can work on a UNIX platform, as well as on Windows or Mac OS X, and can render a scope of up to 255 grayscale colors.
