BIL with mtm-05282e_img.bil Orthoimage data in Band Interleaved by Layer
BIL world mtm-05282e_img.blw format. Stored as 8 bit signed data. There is only
file (blw) and mtm-05282e_img.hdr one layer. Many image viewers can read BIL
a detached format. The world file can be used with many
header file GIS products to geo-locate the image. Projection
information is not included in the file. The
header file (hdr) can be used with software that
understands detached headers to read the BIL
and orthoimage cub file.
