Frank,
Wouldn't this apply to the netCDF grids as well? GMT has always made the
distinction on the area vs point representation. The grids created by
GMT hold that information on the global attribute "node_offset". As for
other netCDF CF grids created elsewhere it is also possible to find
which model is used by checking the grid limits vs array size because
for the same limits the PixelIsArea model has one less row and column
than the PixelIsPoint.

Folks,
After 15 years of denial, and bullheadedness it is now time for me to
admit my interpretation of PixelIsPoint in GeoTIFF files is wrong. To
that
end I have prepared a brief RFC discussing how I intend to fix it. I'd
appreciate comment before calling for a vote.

Mmmm, crow - it tastes just like chicken!
Best regards,
