This is a very interesting idea.
In the IDV, we use a table (xml file) to store all radar stations
information. There are a few APIs in the TDSRadarDatasetCollection class
you can use to get a list of stations. You need to write an API to find
the nearest radar station with the input of lat/lon. This probably the
big hurdle for you. After that, there are APIs already that can be used
to parse the server catalog and communicate with the server. You can
reference the TDSRadarChooser and TDSRadarDatasetCollection classes.
The benefit of using Jython is that you can invoke many Java class
directly, so I think this project is very interesting. Let us know if
you need more help.
