[geotk] Status on reading and displaying netCDF-files

[Westgård Trond]

Hi Martin,
It is about this file:

ftp://ftp.imr.no/geomatys/herring.nc

The file should follow the CF-convention for netCDF files according to one of my colleagues. I really need an example of a working netCDF-example to show to my colleagues.

A small working file as an example would do ! Do you have one ?

I  use the geotoolkit SNAPSHOT both for the geotoolkit and geotoolkit-pending libraries.

The error message when trying to render the file is (so I really never get to the point where the time-slider comes into use .....):

java.lang.AssertionError

Hello Trond

I didn't expected the time- and depth- sliders to be affected... The work on NetCDF files is rather about Coordinate Reference System supports. Could you tell which widget is affected?

    Thanks,

        Martin

In earlier versions of geotoolkit it was possible to render netCDF-files and also to use a time- and depth-slider in the swing display-widget when displaying the netCDF-files.

I know that there is considerable work going on "under the hood" at the moment to rewrite modules that works with netCDF-files.

Is there anyone that knows the timeframe for this work as we need the functionality in one of our projects and must know if we have to go for alternative solutions.
