[geos-devel] Indexing question from a newbie

[Sudipta Sarkar]

Hi All,
I am trying to use GEOS to create envelope geometries for a bunch of 
different tiles and create a spatial index based on these geometries. 
The purpose is to select features lying within a particular tile based 
on an initial query on the spatial index of these different tiles. I am 
a complete newbie to GEOS so was hoping if anyone can suggest as to 
which index amidst Quadtree and SRTree will work best for my purpose. It 
will also be helpful if anyone can point me to any example script in 
C/C++ that uses GEOS to build indexes and query them.

Any help is appreciated.
Thanks
