You could theoretically draw coastlines as VisADLineStripArrays
using ScalarMaps to Shape (see Test47.java and Test46.java in
visad/examples), but its much easier to draw them as a UnionSet
of Gridded2DSets with manifold dimension = 2. This is what
visad.data.mcidas.MapForm does for displaying coastlines from
McIDAS map files. See the Rivers.java program in visad/examples
for an example. Note the Sets have MathType:

  Set(RealType.Latitude, RealType.Longitude)

Good luck,
Bill
