While such data could fit in the VisAD data model,
we have not implemented the necessary classes. We
would need Set classes defining appropriate
interpolation (constant values over cell polygons),
probably a new extension of Field or Function to
alter assumptions in some methods of point samples,
and probably a new extension of DataRenderer. This
would be a lot of work.
You may be able to improve the quality of approximation
to your data by using a higher resolution grid, but of
course at the cost of performance.
