Steve,
I have finished the projection part of NetCDF with the same approach. It is
not checked in yet, but I am planning to do so today. I have created and
computed the following metadata.
Attributes:
Northernmost_Northing (These attributes are used only if there is no
GeoTransform array.)
Southernmost_Northing
Easternmost_Easting
Westernmost_Easting
GeoTransform (this is the GDAL adfGeoTransform array )
spatial_ref (this is the WKT you called esri_pe_string );

Denis,
After discussions with John last year, this is the same approach we have
taken with ArcGIS when exporting to netCDF, and so far it is working well
for us.
When we export to a netCDF file we write projection information as an
attribute of a variable. We call the attribute "esri_pe_string". Of course
we are reading and writing the CF standard projection information when it is
a coordinate system supported by CF.
