ENVI – ENVI .hdr Labelled Raster

Driver short name


GDAL supports some variations of raw raster files with associated ENVI style .hdr files describing the format. To select an existing ENVI raster file select the binary file containing the data (as opposed to the .hdr file), and GDAL will find the .hdr file by replacing the dataset extension with .hdr.

GDAL should support reading bil, bip and bsq interleaved formats, and most pixel types are supported, including 8bit unsigned, 16 and 32bit signed and unsigned integers, 32bit and 64 bit floating point, and 32bit and 64bit complex floating point. There is limited support for recognising map_info keywords with the coordinate system and georeferencing. In particular, UTM and State Plane should work.

All ENVI header fields are stored in the ENVI metadata domain, and all of these can then be written out to the header file.

Creation Options:

  • INTERLEAVE=BSQ/BIP/BIL: Force the generation specified type of interleaving. BSQ — band sequential (default), BIP — data interleaved by pixel, BIL — data interleaved by line.

  • SUFFIX=REPLACE/ADD: Force adding “.hdr” suffix to supplied filename, e.g. if user selects “file.bin” name for output dataset, “file.bin.hdr” header file will be created. By default header file suffix replaces the binary file suffix, e.g. for “file.bin” name “file.hdr” header file will be created.

NOTE: Implemented as gdal/frmts/raw/envidataset.cpp.
