A web interface for PyGnome #28

Open dkobashi opened 7 years ago

dkobashi commented 7 years ago

Dear all,

As far as I checked, it seems that PyGNOME is capable of porting it on the web so that PyGNOME can be run with a custom setting (e.g. particle location (lon,lat,depth), type of oils to be tracked and the amount) selected by users.

I am interested in setting up a web interface like the following websites so that users can run PyGNOME and track particles (e.g. crude oil) with our model output (based on ROMS). http://omgsrv1.meas.ncsu.edu:8080/ocean-circulation-useast2/trajectory.jsp http://www.csiro.au/connie2/ https://ourocean.jpl.nasa.gov/SCB/scbmangen.jsp

I found a few tools NOAA-ORR-ERD provides. However, it's a bit confusing as to how I use each (or all) of the available tools. For example, PyGNOME has a directory called web/gnome. Yet, there are tools called WebGnomeClient and WebGnomeAPI. I wonder if anyone has some tutorial that I can follow to use those tools and to set up a web interface.

Thanks in advance.

Sorry for the confusion -- the "web" dir in the PyGNOME project is an early start that hasn't been touched in years -- we need to remove it.

But we have a pretty full featured Web front end to GNOME -- all in the other repositories you have seen:

WebGnomeAPI is a Python application that provides an JSON http API to drive PyGNOME

WebGnomeClient is a Javascript "Rich Client, Single Page" app that provides the full browser interface -- it is designed to talk to the WEbGNOMEAPI.

You will also need the OilLibrary and OilLibraryAPI projects if you want to run "real" oils.

I'm afraid the documentation on how to install the entire stack is pretty sparse -- I'll see if I can find more.

You can see a test version of the Web Interface live here:

Thanks for your reply, Chris.

WebGNOME is close to what I am envisioning. What I am interested in is that we (our research group) provide forecast model output daily based on ROMS and would like potential users (in particular non-tech users) to use the model output with the oil spill setting (location, amount etc) of their own.

I took a look at the test version of the interface live you mentioned. It looks great and thanks for the efforts from your group to make this work. One thing I would like to know is whether we can use OPenDAP address to load current and wind data. It looks like we can include gridded current and wind in NetCDF format; however, if we need to include actual netcdf files, we need to ask users to download the data first from our THREDDS server before loading the file into WebGNOME. That's not necessaily efficient given that the file size of our forecast model output is ~25 GB (full 3-D data). Our preferred method is to use OPeNDAP. I tested PyGNOME with loading current/wind files via OPeNDAP and it seems to be working fine so far. I wonder if you can add the function to WebGnome (or do you have the function in place already?). I believe it would be a very useful function to WebGnome.

Thanks,

DJ

Yes, that will be possible -- hopefully soon.

As you have seen, the functionality is in place in PyGnome -- so we just need to hook up the UI for it.

We are also planning on making "Locations" that are pre-connected to particular operational forecast models-- like yours, for instance.

Thanks, I look forward to the function. Additing the "Locations" connected to operational forecast models sounds great. We run two forecast models daily: one for the Texas-Louisiana Shelf (full 3D) and the other for the Gulf of Mexico (barotropic). Bests, DJ@TAMU
