      The directory TOPO contains the Commission's topographic data
      base and the FORTRAN subroutines that should be called by various
      application programs to read the topo data and calculate 
      height above average terrain ( HAAT ). This directory also contains
      routines needed to convert the raw topo data to the compressed
      format of the production data base. The name of the production
      data base is TOPO.DAT.  There are five files that contain the 
      raw data. They are:
 
                     file name        blocks
                     ---------        ------
                     topo1.dat        37234
                     topo2.dat        38475
                     topo3.dat        22002
                     topo4.dat        36444
                     hawaii.dat        2230
 
      On April 28, 1989 the entire TOPO directory was copied to tape
      and put into the Honeywell tape library. The honeywell tape
      name is BXX001P1TOPO. Two copies were made. One copy is stored
      on site in the tape library, the other copy is stored off site.
      After the tapes were made, the above 5 raw data files were deleted
      in order to recover the disk file space because we are having a 
      shortage of file space to develope new systems and data bases.
