Much of what we do now with the metapps code is done in the
context of the Integrated Data Viewer (IDV) and in that case
we use the ucar.visad.ShapefileAdapter to create VisAD Data
objects from the shapefiles.  This gives us sets of the points
of the polygons.  We then pass that to a ucar.visad.display.MapLines
object which then gets added to a DisplayMaster.  The latest
release of the IDV allows you to load a shapefile and display
it in the main display.

What class are you using to display sounding data?  Are you
doing plan view plots or skew-Ts?  Which class do you want
to use to view your lines?
