What is a .BSQ file?
BSQ is a band-sequential raster, storing each image band one after another.
- Did you know
- BSQ keeps each band of a satellite image as a complete separate layer.
- BSQ is one of three companion layouts - alongside band-interleaved-by-line (BIL) and band-interleaved-by-pixel (BIP) - for multi-band imagery.
- Landsat Thematic Mapper scenes were distributed in BSQ form, with each spectral band stored as a complete separate block.
- What Analyser reads
- Identify and read more GIS and mapping files: OpenStreetMap o5m/o5c binaries, Esri layer files (.lyrx ArcGIS Pro CIM JSON, .lyr ArcMap), QGIS projects (.qgs/.qgz - version, CRS, layer list), shapefile spatial indexes (.sbn/.sbx), GMT/GDAL colour palettes (.cpt) and ENVI band-interleaved rasters (.bil/.bip/.bsq).
- Depth of analysis
- .BSQ is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .BSQ file
- Drag a .BSQ file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
