    77The Eagle data is captured as ENVI format BIL files (a pair of .hdr and .raw), with an associated nav file. The .hdr files are ASCII text files where as the .raw and .nav are binary data files.

    9 The Eagle .raw data files contain 12-bit data (values of 0-4095) stored as 16-bit integer. The first pixel of the first band of each raw file is the frame counter pixel, which is essentially a frame id tag that increments by 1 through out the file. At the end of the raw file, after data capture for this flight line, a number of lines of data are captured with the shutter closed. These lines are refered to as "dark lines" and give sensor ccd values for when no light is present.

    1111The .nav files are a collection of different 'messages'. These contain the real-time position and attitude of the aircraft as well as periodic time stamps marking the start of the flight line capture.
