Hi Stuart, In hindsight, contours were not a good example of what I am wanting. What I am wanting is to be able to interpolate gridded data sets, so I can put in a lat/lon and obtain a field value, preferably using a Jython method. It would be good if IDV has a Jython method that could do this. Paul Graham On 3 January 2013 10:42, Stuart Wier <wier@xxxxxxxxxx> wrote: > Paul, > > Given: > > > Thanks for your reply.
