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.
