This may or may not help but the surface elevation grid should have a GVCORD
= NONE and a GFUNC = HGHT.

Hello all.
I have a set of scripts that was running fine with the older 20km RAP grids,
for the calculation of DCIN. Since the change to the 13km grid delivery in
late June, those scripts no longer work. (Yes, the necessary file naming
strings have been updated.)
The fundamental operation in question seems to be the use of GDVINT to
interpolate to ZAGL, with the dread warning '[GDVINT 4] Warning--no surface
elevation grid exists.' Even so, GDINFO shows:
247 220831/2100F000 0 NONE PRES
25+ years of writing these kinds of scripts, and I am now stumped. Any
thoughts on how to rectify would surely help.
Thanks,
Pat
