Faster

Hi everybody:

I am working on an application that plots radar data. The radar data is
a 512x512 matrix (262144 pixels), using a Integer2DSet  and I haven't
had any problems about speed (just the usual Java speed). But now I`ve
been tried to plot a contour map over the radar image, the map
coordinates are composed by some polylines in a text file (.MIF). I made
a class that reads the file and store each polyline in a float[][]  and
then I do just like the rivers.java example: Create an array of
Gridded2DSet and then an UnionSet and into a DataReference.

But after that the application speed became very slow (the map is not
that big aprox. 10000 points). I've seem some other application that use
maps and Visad, and they are fast.

I don't know what the problem is. Any help is welcome.

Thanks alredy:
