Hi CJ:
We are recommending that new netCDF data follow the CF "discrete
sampling" data proposal at:
https://cf-pcmdi.llnl.gov/trac/wiki/PointObservationConventions
Unfortunately, it is not a final standard yet, and has changed a bit in
the last week. However, Im hopeful its very close. See section 9.4 for
trajectory data. Any comments on that proposal would be appreciated, in
particular if it meets your needs. If you'd like to try putting it
into that format and sending us a sample file, we may be able to the
process .
You can use any software to write netCDF, Java is not needed. The IDV
will be able to read that format (not the current release, but soon
after).
Regards,
John
Hello Ben,
I've been talking with Tiffany Vance and Steve Hankin about our data
and visualization needs for the incident. I'm one of the trajectory
modelers with NOAA Office of Response and Restoration / Emergency
Response Division, and working on making new kinds of displays for
information. We have the lead for modeling for the incident, and are
putting out the daily trajectory forecasts. We are moving quickly to
3D forecasting. I have questions along two lines.
netCDF - we are pushing for using netCDF for all the information
management for the modeling team. The two data streams are to move
things into GIS for the spatial folks, and netCDF for those of us doing
modeling and obs analysis. We have some issues that Unidata may be
able to help with. For example,
-we use the C libraries that always seem to be behind the java
libraries in development
-are their standards now for trajectory, cruise profiles, glider data,
etc? We will have a large number of observational platforms, and want
to be able to leverage all the data in modeling and forecasting.
Visualization - IDV. I'm an IDV novice, but a big fan. Working on the
HabitatSpace project with Tiffany, we ran into some little bugs that
caused headaches. In looking at how to do 4D visualization for obs and
models, I'd really like to use IDV. Is there help available to make
sure that it works for what we need?
If you need more background on our needs, or what we do, let me know.
Best regards,
CJ
