Unidata has developed classes for reading map files in ESRI
Shapefile format which can be used with VisAD. We have a
ucar.visad.ShapefileAdapter class that will create a UnionSet of
SampledSets representing the Shapefile. I notice that OpenMap has their
own classes for reading Shapefiles, but have not investigated OpenMap
very much. You might be able to do something similar by creating a
DCWAdapter that adapts the DCW data in OpenMap to a VisAD Data object.
I'm not familiar with the DCW format. You can access our code from the
link off the VisAD homepage or directly at:
