What is a .BIL file?
BIL is a band-interleaved-by-line raster, common in remote sensing.
- Did you know
- BIL interleaves a satellite image’s colour bands line by line.
- BIL is one of three interleaving schemes - by line, by pixel and band sequential - rather than an image format in its own right.
- It always travels with a matching ASCII .hdr header file that describes the raster’s dimensions and layout.
- 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
- .BIL 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 .BIL file
- Drag a .BIL 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.
