Re: [gembud] GDVINT: [GDVINT -15] Grid size is too large.


Just a guess, but perhaps the input file is the source of your problem.  This 
might be possible if you got the file from someone with a different version of 
Gempak that has larger limits on the number of X/Y points in the configuration.

Have you tried gdinfo, or gdplot to work with just the input file?

Good luck,

Subject: [gembud] GDVINT: [GDVINT -15] Grid size is too large.


I'm trying to use GDVINT to convert a gem file of RAP data from its native 
sigma coordinates to pressure coordinates.  Here is my input:

 GDFILE    Grid file                         
 GDOUTF    Output grid file                  2014012812_presvcord.gem
 GDATTIM   Grid date/time                    f000
 GVCORD    Grid vertical coordinate          sgma:10/pres
 GLEVEL    Grid level                        100-1000-50
 MAXGRD    Maximum number of grids           5000
 GAREA     Graphics area                     30;-100;50;-60
 VCOORD    Vertical coordinate type          none;hght

However, I encounter this error:

 [GDVINT -15]  Grid size is too large.

I'm not really sure what this means, since I've tried reducing the GAREA all 
the way down to a 1x1 lat/lon square, and MAXGRD to 1, and GLEVEL to 
900-1000-50, and even have run with all three of these minimalist settings at 
once, yet encounter this error every time.  Which thing is too large, and how 
do I make that thing smaller?
