RE: [las_users] how can I join multiple netcdf files to generate a big animation?

["Serra, Mr. Efren, Contractor, Code 7542" <efren.serra.ctr@xxxxxxxxxxxxxxx>]

Folks,

 

Never mind my previous email; this is what I needed to do to get it just like I needed it:

 

<netcdf xmlns="http://www.unidata.ucar.edu/namespaces/netcdf/ncml-2.2">

      <aggregation dimName="time" type="joinNew">

        <variableAgg name="salinity" />

        <netcdf location="file:/godae/home/ftp/pub/outgoing/static/ocn/gdem/sgdemv3s01.nc"/>

        <netcdf location="file:/godae/home/ftp/pub/outgoing/static/ocn/gdem/sgdemv3s02.nc"/>

…

 

        <netcdf location="file:/godae/home/ftp/pub/outgoing/static/ocn/gdem/sgdemv3s11.nc"/>

        <netcdf location="file:/godae/home/ftp/pub/outgoing/static/ocn/gdem/sgdemv3s12.nc"/>

      </aggregation>

</netcdf>

The way we recommend to accomplish this is to create an aggregation using the THREDDS data server.  Since you likely already have a TDS installed along with your LAS you can create a "join existing aggregation" in that server and use the resulting URL as input into LAS.

You can probably piece together how to do this by studying the TDS tutorial here: http://www.unidata.ucar.edu/Projects/THREDDS/tech/tutorial/NcML.htm

I'll make a note to our group to create some documentation for how to do this since it's what we recommend and is an FAQ for us.

Hi guys!

 

Hi have files containing information from a prediction model, something like this:

 

1_NATL3-JREF2.3_y2004m01_gridT.nc

1_NATL3-JREF2.3_y2004m02_gridT.nc

1_NATL3-JREF2.3_y2004m03_gridT.nc

1_NATL3-JREF2.3_y2004m04_gridT.nc

1_NATL3-JREF2.3_y2004m05_gridT.nc

1_NATL3-JREF2.3_y2004m06_gridT.nc

…

..

.

 

Each file contains information from one month, so right now I’m being able to see animations from one month, but what I want is to make animations from the whole year, I don’t know exactly how to do this, maybe making a xml in threads, or modifying the xml that describes each dataset.

 

I would appreciate if any of you guys can give me a guide to do this!

 

Regards
