Hi Steve,

I've been working on the conversion of a MM5 operational run to Gempak, also
looking forward it's distribution over IDD-Brazil. DCGRIB2 converted without
errors the original grib, however both nmap2 and gdplot were uncapable of
plotting any requested variable. They've displayed this error message:

 [GEMPLT -16]  NIPBND - Invalid projection bounds.
 [GEMPLT -16]  NIPBND - Invalid projection bounds.
 [DG -37]  No reference grid navigation is set in GPLT.

according to gdinfo, this is the configuration of the grid:

 GRID NAVIGATION:
     PROJECTION:          LCC
     ANGLES:               -20.0   -43.0   -26.0
     GRID SIZE:           50  50
     LL CORNER:             -27.33    -47.96
     UR CORNER:             -20.99    -41.15
 GRID ANALYSIS BLOCK:
      UNKNOWN ANALYSIS TYPE
 Number of grids in file:    13
 Maximum number of grids in file:  29999
  NUM       TIME1              TIME2           LEVL1 LEVL2  VCORD PARM
    3     050525/0000F006                          0         HGHT PRESHAG
 Parameters requested: GDFILE,LSTALL,OUTPUT,GDATTIM,GLEVEL,GVCORD,GFUNC.

The grid is located over Rio de Janeiro, Brazil, and, for testing purposes,
only one level (1000) and one time were used.
I've also generated the conversion tables and, as far as I know, they're
working correctly. Any ideas on where my error might be? 

Best Regards,
