IOOS COMT-funded project to enable ugrid as a first class citizen in netcdf-java and thredds
For more information, please see the project wiki
A draft of the project transition plan is due by the end of the first year. More details to be added as we get them.
As mentioned at the meeting today, we should clarify what is meant by supporting UGRID.
Triangle, quad, hex, meshes? Full 3D unstructured topology?
For sure, support output from FVCOM , ADCIRC, SCHISM. Anything else? Please add pointers to samples here.
Submit abstract for AGU 2019 to showcase the new UGRID capabilities of the TDS.
We will need to update the issue labels (e.g. "good first issue" is not particularly useful for this project, should probably add "Deliverable" as a tag, etc.)
Expose one or more UGRID datasets via FMRC on the Unidata test TDS (thredds-test.unidata.ucar.edu) for wider testing. Use this system for #10.
Should we enable the wiki on this repo? I think it would be useful, so +1 here
The NOAA CO-OPS operational forecast model for San Francisco Bay is not currently UGRID compliant.
The THREDDS catalog is here:
https://opendap.co-ops.nos.noaa.gov/thredds/catalog/NOAA/SFBOFS/MODELS/catalog.html
And if you look for the data with fields
in the name, these are output from the unstructured triangular grid FVCOM model.
They only keep a few weeks of data on the thredds server, so in a few weeks the dates in this URL will need to be modified to work:
@kwilcox, do you have some NcML for them to add to their THREDDS catalog to make this UGRID compliant?
Expand Coverage FeatureType
, or create a new UGRID FeatureType
, to support the use of UGRID in TDS FMRCs. Scope of work to be based on results of #7.
Identify areas in which Coverage FeatureType
falls short of supporting unstructured grids. Produce a summary document (blog post?)
Use this ticket to point to UGRID datasets to be used for development and testing.
triangle mesh
hex mesh:
hybrid mesh:
Create basic maps, charts, etc. of various fields within UGRID datasets as exposed by the TDS via FMRC.
edit: these should, at the very lest, be driven by the functionality tested in issue #6
With some CI pipelines so we can update THREDDS configs/dataset here in GitHub and they can be deployed to the server automatically.
Create unit and integration tests based on the unstructured grids represented by the sample collection.
