Re: [netcdf-java] problem getting axistype

the coordinate systems look ok to me. the lat and lon axis types dont get recognized because they use degrees as units instead of degrees_north and degrees_east, respectively, as CF requires. thats why you will get a null in your code.
the grid display looks wrong, however, probably because X has "100 km" units, and y has nothing, so km is assumed.
using the CoordSys tab of ToolsUI is one way to look for these kinds of issues.

Hi John,

The dataset is available here:

Cheers,

Hi John,

The underlying question is, why doesn't java-netcdf recognize the axis
type?  Previously (with the same dataset) the axis was recognized as
GeoX/GeoY, but now something has changed and it isn't.  I think
something has changed with the remote dataset but I can't see from the
metadata (Adit provided an ncdump) what is wrong.  The dataset is in
polar stereographic projection - is the metadata set up incorrectly or
is there a bug in java-netcdf?

Cheers, Jon

Hi Adit:

The AxisType is optional, so you need to check for null.

ok, thats a clearer question. Adit, can you send me the actual file?
