FAQ
BSQ to FLIF 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 FLIF files?
FLIF (Free Lossless Image Format) is a royalty-free format launched at the end of 2015 as "work in progress" with the aim of offering a better alternative for storing lossless images than the existing PNG, WebP, BPG, JPEG2000 and JPEG XR. FLIF provides similar image quality as the other extensions, but in a file size than can be up to 74% smaller. The new format uses a form of the Adam7 algorithm for compressing images, offering progressive interlacing that allows users to obtain a reasonable encoding of an image even from a partial download.
