Re: Netcdf CDM and ragged arrays

Hi all:
you are seeing some issues with CDM version being behind the CD spec, The next CDM 4.3 release will fix these, possibly this week.

Andy -

I got this working by adding the "standard_name = station_id" attribute to the 
"station_name" variable.

Use this (change path to NetCDF file as needed):

<?xml version="1.0" encoding="UTF-8"?>
<netcdf xmlns="http://www.unidata.ucar.edu/namespaces/netcdf/ncml-2.2"; 
location="C:/Users/kwilcox/Desktop/watlev_NOAA.F.C_IKE_VIMS_3D_WITHWAVE.nc">
   <variable name="station_name">
     <attribute name="standard_name" value="station_id" />
        </variable>
</netcdf>

Hi Ethan,

Thank you for getting back to me. Please find attached a small example of an 
IMEDS file netcdf ragged array. I can provide many more links via opendap if 
required.

The data is typically multi station time series data. Alex can provide the 
detailed information on the netcdf construction and outline if needed.

Best,

Andy

Hi Andy,

Yes, a sample would be great. What type of data are you working with?
Point data, soundings, etc?

I'm CCing John Caron who wrote the FeatureDataset code. I believe there are 
some fixes in 4.3 but I'll let John speak to that in more detail.

Thanks,

Ethan

Can you send along the NetCDF file you are working with?

Hi Ethan,



I was wondering if you could help with a small problem we are having,
we are trying to update one of our THREDDS services to work with
ragged arrays but are having some issues with the
FeatureDatasetFactoryManager.wrap command returning a null object when
parsing the netcdf feature type information. We are using version 4.2
of the netcdf tools. Kyle's thoughts were that some of the issues we
were having might be fixed in version 4.3??



Happy to provide more information if needed.



Andy Bird
