Dear S-PLus news list,
Does anyone know if it is possible to read and write BSQ, BIP or BIL file
formats in S-Plus?
thanks

Description of the file formats as copied from ENVI:
BSQ (Band Sequential Format)
In its simplest form, the data is in BSQ format, with each line of the data
followed immediately by the next line in the same spectral band. This format is
optimal for spatial (X, Y) access of any part of a single spectral band.
BIP (Band Interleaved by Pixel Format)
Images stored in BIP format have the first pixel for all bands in sequential
order, followed by the second pixel for all bands, followed by the third pixel
for all bands, etc., interleaved up to the number of pixels. This format
provides optimum performance for spectral (Z) access of the image data.
BIL (Band Interleaved by Line Format)
Images stored in BIL format have the first line of the first band followed by
the
first line of the second band, followed by the first line of the third band,
interleaved up to the number of bands. Subsequent lines for each band are
interleaved in
similar fashion. This format provides a compromise in performance between
spatial and spectral processing and is the recommended file format for most
ENVI processing tasks.
