Hola,


Touché! :-)

The processing is now very fast.

2.- Use the same renderer as shape files. (Faster). The only thing you

ho la la la la !!!!!

Ok.  The aim is to optimize spatial partitioning. No ? I don't understand
when I must use BoundedShapes.
Could you explain me?

Muchas gracias.

R1.

I didn't tryed it, but with this two modifications, it should go faster.
