Re: Map Display

Hi John,
 
You'd have to construct your river system or circle as VisAD
Sets with domain dimension = 2 and manifold dimension = 1.
There are constructors for Gridded2DSet that do this.  For a
set of line segments, you'll need to construct a UnionSet of
a bunch of Gridded2DSets, each with manifold dimension =1.
Please let me know if you have further questions or problems.
 
Cheers,
Bill
