Binary Interleaved by Line BIL Format

BIL Description: Binary Interleaved by Line or BIL is a image file stored in one format or another to ease manipulations.

BIL basically is a compromise format to easily pull spectral and spatial gis mapping information. 

These files are usually accompanied by a .hdr file which describes the layout and formatting of the file. 

Global Mapper requires this .hdr file in addition to the .bil, .bsq, or .bip file in order to load the file.

Available for free? Sometimes, this is a generic format used by many different data providers, so the cost of the data in these formats varies.
