Hi All,
I am trying to create a spatial index on my shapefile polygon data, 
unhomogenously distributed over space (read only) for a point in polygon 
type of queries, and I have two options - either use a qix (that's a 
quadree, right?) or use

final SpatialIndex index = new STRtree();   

I like the second option, but am wondering how I could save the results of the 
indexing for future use. In other words, I need to introduce persistence.
Alternatively, I guess I could just generate a qix index and use that, but I 
wanted to try the STRtree, as I think it is better suited for my data.
Cheers
Martin
