HDFDUMP and BRFDUMP are  utility programs developed for use with MISR datafiles.  HDFDUMP will extract data from a MISR file in the HDF-EOS grid format(MISR Level 1B2 and Level 2 files) and writes unformatted binary files.  BRFDUMPcalculates radiances and bidirectional reflectance factors (BRF) from MISR Level 1B2files and creates unformatted binary files.These programs are written in Fortran 90 and have been tested on an SGI Origin2000 running IRIX 6.5 with the MIPSpro 7 Fortran 90 compiler.  The pre-compiledexecutables supplied in the package were built in -n32 -mips4 mode on an SGI,suitable for the R8000, R10000 and R12000 cpus normally found in Challenges andOrigins.  In order to build these programs it is necessary to have the HDF and HDF-EOSlibraries for the target computer.  The HDF libraries are available from theNational Center for Supercomputing Applications:	http://hdf.ncsa.uiuc.edu/	and the HDF-EOS libraries are availble from the EOS project at	http://hdfeos.gsfc.nasa.gov/hdfeos/SoftwareDist.html	Two unix script files have been included which will compile these programs,bld.hdfdump and bld.brfdump.  These scripts will need to be modified toreference the installed locations of the HDF include and library files and theHDF-EOS include and libary files on the target computer.
