How do I use MULTIBAND read to read a BIL file

The raster file in .BIL format can be read using the MULTIBAND function in the Mapping Toolbox. The arguments to the function are all obtained from the corresponding fields of the header file.

filename ='MyFiles\Bil\45765067\45765067.bil';

% From the .hdr file, I obtained the following arguments for the MUTLIBANDREAD function.

size =      [ 1383 1621 1];      % [ NROWS NCOLS NBANDS]

precision = 'int16';                  % from NBITS and PIXEL TYPE = int

offset = 0;                              % since the header is not included in this file

interleave = 'bil';                     % LAYOUT

byteorder = 'ieee-le';              % BYTEORDER = I (refers to Intel order or little endian format)

X_bil = multibandread(filename, size, precision, offset, interleave, byteorder);

figure, imagesc(X_bil)               % Display the image file using IMAGESC

demcmap(X_bil)                        % Changing the colormap
