Selfe File Schema

[alireza.rm]

 
Dear All,

Does any one know the schema of selfe files? I could not find any resource which clarify this.
I looked at here but it is hard to figure out the details of each format. In particular I am
interested in "DataFormat v5.0 " schema. Please if you know the schema or you know
some resources which discuss it let me know.

Thanks,
Best,
Alireza

Binary DataFormat v5.0 files are documented at http://www.stccmop.org/CORIE/modeling/selfe/input.html#Global%20output2

NetCDF output files from SELFE have been produced a number of ways, using the combine_output* scripts from http://www.stccmop.org/knowledge_transfer/software/selfe/utilities, or from the the SVN archive. I've made a number of them converting from the binary DataFormat v5.0 directly to netcdf.

The earlier files mostly conform to an earlier HydronetCDF scheme ( http://ches.communitymodeling.org/models/POMches/netcdf.html ) while more recently generated ones have been more ugrid compliant. With the SURA/testbed/comt projects, we've mostly added metadata with NCML to make the files more compliant.

If you look here:

https://github.com/pyugrid/pyugrid/tree/master/test_bed

There is some same code (not written by me) that reads SELFE files -
not sure what version, but maybe helpful.

Note that that code is Not integrated with py_ugrid.

Also, while not designed for this, py_ugrid can help serve as a
compliance checker for ugrid netcdf files.

Hi Dave and Chris,

Thanks for your replies.

Perhaps I was not very clear on my demand. I know there tools to convert selfe to netcdf and other formats and also
reading it. What I am looking  is to make a schema of the file which for instance says: the header contains
these fields with this order, then it comes the hgrid which contains x,y,z,b and then it comes the time varying part, etc.

Currently I am able to read the header and the hgird correctly. My actual problem is to figure out the schema of the time varying part.

The documentation here http://www.stccmop.org/CORIE/modeling/selfe/input.html#Global%20output2  is not very clear about the schema.

Please if you know how figure this out help me.

Thanks,
Best,
Alireza

It seems this discussion would be better suited to a SELFE discussion forum or an offline discussion since it deals with SELFE custom binary format, not UGRID conventions

Hi Rich,

Could you please give me the name of the SELFE discussion forum?
I have googled but could not find it.

Thanks,
Best,
Alireza

I was assuming you wanted the schema so that you could write a reader. But in any case, reading the source code of functional readers should give you the schema.

Hi Chris,

By functional reader, are you referring to the code in here https://github.com/pyugrid/pyugrid/tree/master/test_bed  ?
