Thanks for the heads up, I've not used GMT versions of NetCDF much, or
recently. The vast majority of NetCDF I've had to work with do not
make this explicit, and this is about the most detailed discussion

Cheers, Mike.
Mike,
Meanwhile I found (should know it by hart, though) how GMT does it. The
info is stored on a global attribute
"node_offset".
0 for grid registration (pixel-is-point) and 1 for pixel registration
(pixel-is-area)
Furthermore, when reading grids created by other programs that do not
store that info GMT guesses the grid type based on the array size and
the coordinates limits.

netCDF grids created by GMT have always (~20 years) made that distinction
